# Changelog

All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [2.11.0] - 2026-05-19

### Important

- **.NET 10 upgrade** — Dashboard, Lite, Installer, and Installer.Core now target `net10.0` (Windows projects target `net10.0-windows`). Building from source now requires the .NET 10 SDK; CI is pinned to 10.0.204 via `global.json` for reproducible builds. End users running prebuilt Velopack installers do not need to install anything separately — runtime is bundled ([#958])
- **Setup.exe is now the recommended install path** for Dashboard and Lite — the README steers users to the Velopack `Setup.exe`, which installs to `%LocalAppData%`, registers the apps under Apps & Features, creates Start Menu and Desktop shortcuts, and wires up auto-update. Portable ZIPs are still produced for both apps (CI release pipeline and local build scripts) as a fallback for advanced or air-gapped users. The Installer ZIP (CLI installer + SQL scripts) is unchanged
- **Shared `servers.json` location** — Dashboard and Lite now store `servers.json` under `%ProgramData%\PerformanceMonitor{Dashboard,Lite}\` so every Windows user on the same machine shares one server list. First run migrates an existing per-user `servers.json` to the new location and grants Authenticated Users Modify on the directory. SQL credentials remain per-user in Windows Credential Manager — each DBA re-enters SQL passwords on first connect; Windows Auth works with no re-entry

### Added

- **One-click snooze from the alert tray popup** in Lite — snooze an alert directly from the tray notification balloon without opening the main window ([#944])
- **Snooze hint in email and Teams/Slack alert payloads** — alert messages now show the snooze duration / scheduled wake time when an alert is fired while a snooze is active ([#944])
- **Process memory logging per collection cycle** in Lite — the collector now logs working set and private bytes at the end of each cycle, making it easier to track memory growth in long-running sessions

### Changed

- **Lite compaction memory tuning** ([#933]) — multiple changes to make parquet compaction robust on wide-row tables and large datasets:
    - Cap the main collector connection's `memory_limit` and raise it transiently only for the `COPY` step
    - Detect compaction `EXCLUDE` columns per merge step instead of once up front
    - Raise the compaction `memory_limit` floor to 4 GB
    - Set DuckDB `temp_directory` explicitly so spill files don't blow the OS temp drive
    - Compact parquet in size-budgeted batches instead of one mega-batch
- **Trace collectors honor `config.collector_database_exclusions`** ([#887] follow-up) — the trace-file based collectors now filter against the exclusions table, matching the behavior of the eight DMV-based per-database collectors shipped in v2.9.0
- **InstallerGui project directory removed** — the WPF InstallerGui was retired in v2.9.0 in favor of the Dashboard's integrated Add Server dialog. The project directory has now been deleted from the repo
- **Build warnings cleaned up** across Lite, Dashboard, and Installer ([#945])
- **GitHub Actions runners bumped** to Node 24-compatible major versions to silence deprecation warnings

### Fixed

- **Re-run `installation_history` column widening** for servers that crossed v2.4.0 → v2.5.0 before PR #828's fix shipped in v2.7.0. Those servers ran the original widen script as a no-op against `master`, then advanced their installer_version past 2.5, so the now-fixed script never reapplied. Adds an idempotent ALTER under an `IF EXISTS` guard checking `max_length = 510` ([#828])
- **Mute rules preserved across size-triggered DuckDB reset** in Lite — when the local DuckDB exceeded the configured size budget and was reset, mute rules were being lost. They now survive the reset ([#938])
- **Chart tooltips break after tab switch** — root-cause fix for the popup-wedge issue first patched in v2.10.0. Both the Memory tab handlers and `CorrelatedCrosshairManager` are now resilient to tab churn ([#916], [#937])
- **Stale `Monitor_LongQueries_*.trc` files cleaned up** by `config.data_retention` — the trace-file cleanup step previously left old `.trc` files behind on disk ([#951])
- **Nullability guards** added to the remaining comparison overlay tasks that were producing CS86xx warnings

## [2.10.0] - 2026-05-04

### Fixed

- **Memory tab tooltip** stops working after switching away and returning to the tab. Both Dashboard and Lite Memory tab crosshair tooltip handlers now reattach correctly on tab re-entry; the same popup-wedge fix is also applied to `CorrelatedCrosshairManager` ([#916])
- **FinOps memory recommendation** now bases sizing on a 7-day P95 of memory samples instead of a single snapshot, so recommendations no longer swing based on instantaneous workload state. Applied in both Dashboard and Lite ([#917])

### Changed

- **Per-database grants for FinOps Index Analysis** documented in the README — sp_IndexCleanup-backed Index Analysis requires per-database `EXECUTE` grants on each user database you want to analyze ([#915])

## [2.9.0] - 2026-04-29

### Important

- **Breaking change to `config.data_retention`** — the `@truncate_all` parameter has been removed. Pass `@retention_days = 0` for the same behavior. `@retention_days = NULL` (default) respects per-collector retention from `config.collection_schedule` with a 30-day fallback for unscheduled tables; `@retention_days = N > 0` overrides every table to N days. Any existing Agent jobs or scripts calling `data_retention @truncate_all = 1` need to be updated ([#900])
- **New `config.collector_database_exclusions` table** for per-database collector exclusions. Eight per-database collectors filter against this table; system databases remain hard-skipped by the collectors themselves. Existing installs get the table on the next upgrade — `install/01_install_database.sql` and `config.ensure_config_tables` both create it under an `IF OBJECT_ID … IS NULL` guard ([#887])

### Added

- **Per-database collector exclusions** — exclude noisy or unimportant databases from per-database collectors. Dashboard side adds `config.collector_database_exclusions` and filters 8 collectors (`query_stats`, `query_store`, `procedure_stats`, `file_io_stats`, `waiting_tasks`, `database_configuration`, `database_size_stats`, `server_properties`). Lite side adds an `ExcludedDatabases` list per server in `servers.json` and filters 9 collectors ([#887])
- **`Off` collection preset** — `EXECUTE config.apply_collection_preset @preset_name = N'Off'` disables every collector in one call. Pair with a second Agent job that applies a non-`Off` preset at the start of your active window for overnight / quiet-hours scoping. Non-`Off` presets now also set `enabled = 1` across the board so the switch from `Off → Balanced` reliably resumes collection ([#888])
- **Purge Now action** in Manage Servers — confirm dialog with a mode picker (Use configured / 1 / 3 / 7 / Custom / All) drives `config.data_retention`; right-click menu on the Manage Servers grid mirrors every per-row action (Edit, Toggle Favorite, Check Server Version, Purge Now, Remove) ([#900])
- **Total non-idle CPU on Lite Overview** — headline value shows total CPU with the SQL-only value alongside (e.g. `64% (SQL 60%)`); new `CpuAlertMode` dropdown in Settings → Alerts (Total / SqlOnly) drives both the alert evaluator and headline color; tray notifications and email alerts label the value as "Total CPU" or "SQL CPU" ([#899])
- **Resume gap detection** — `query_stats`, `procedure_stats`, and `query_store` collectors skip the historical sweep on first run after an Off preset, Agent stoppage, or server reboot. When the last successful run is older than 5× the configured `frequency_minutes` (floored at 30 minutes), the cutoff clamps to `SYSDATETIME()` so only forward-going data is collected on resume — preventing the tempdb blowout that hit the original reporter ([#892])
- **Right-click View Plan** on Dashboard Blocked Process Reports (View Blocked Plan + View Blocking Plan), Dashboard Deadlocks, and Lite Deadlocks grids. Plan lookup hits `sys.dm_exec_query_stats` + `sys.dm_exec_text_query_plan` on the monitored server, falling back to `executionStack/frame` entries when the process-level `sql_handle` is empty or evicted ([#880])
- **Open Log Folder** sidebar button in Lite — opens `%LocalAppData%\PerformanceMonitorLite\logs\` in Explorer for grabbing historical logs to attach to bug reports. Sits below View Log, which retains its existing behavior of opening today's log file ([#873])
- **Installed Version column** in the Manage Servers grid for both Dashboard and Lite. Dashboard shows the PerformanceMonitor database version on each server (probed in parallel via `GetInstalledVersionAsync`, with `Not installed` / `Unavailable` fallbacks). Lite shows the running app's own version on every row, mirroring Full's column header for consistency.
- **Lite-style server card indicators in Full** — back-ported the Ellipse-with-DataTriggers status dot (Online/Offline/Warning/Unknown) and the right-aligned favorite star from Lite to the Full Dashboard's server list, matching Lite's visual treatment.
- **Architecture overview** at `docs/how-collection-works.md` covering the minute loop, dispatcher, collector shape, `config.collection_schedule`, retention, and the Dashboard read path

### Changed

- **PlanIconMapper synced** with PerformanceStudio v1.9.0 improvements — columnstore storage type on scan/delete/insert/update/merge operators routes to `columnstore_index_*` icons (covers CCI and NCCI); `Parallelism` operator subtypes (Repartition Streams, Distribute Streams, Gather Streams) get their own icons
- **`Microsoft.Data.SqlClient` 6.1.4 → 7.0.1** — major-version bump. Azure/Entra dependencies were split out of the core package in 7.0; `Microsoft.Data.SqlClient.Extensions.Azure 1.0.0` added to Dashboard, Lite, and Installer.Core for `ActiveDirectoryInteractive` connections
- **`ModelContextProtocol` 0.7.0-preview.1 → 1.2.0** — off the preview tag and onto stable 1.x in Dashboard and Lite
- **`DuckDB.NET` 1.5.0 → 1.5.2** in Lite — fixes unbounded row group growth on indexed tables under repeated load+insert cycles, memory leaks and race conditions in prepared statements, WAL checkpoint marking, and Windows UTF-8/UTF-16 handling
- **`Microsoft.Extensions.*` 10.0.5 → 10.0.7**, **`System.Text.Json` 10.0.5 → 10.0.7**, **`ScottPlot.WPF` 5.1.57 → 5.1.58** — patch-level bumps with no expected behavioral change
- **Theme polish** on grids and plan viewer in Dashboard and Lite — thanks [@ClaudioESSilva](https://github.com/ClaudioESSilva) ([#889])

### Fixed

- **Install loop timeout** raised from 5 minutes to 1 hour. `install/98_validate_installation.sql` runs every enabled collector with `@debug = 1` in a single batch; on large databases (reporter had 7.2M rows in `collect.query_stats`, 4.4M in `collect.query_store_data`) this took ~9 minutes and was blowing the 5-minute timeout, failing the install or upgrade ([#884])

## [2.8.0] - 2026-04-22

### Important

- **New nonclustered indexes** on `collect.query_stats`, `collect.procedure_stats`, and `collect.query_store_data` to eliminate Eager Index Spools in Dashboard grid queries. On large installations these indexes may take several minutes to build; the upgrade script uses `ONLINE = ON` on Enterprise/Developer/Azure editions and falls back to offline on Standard/Web ([#835])

### Added

- **Memory Pressure Events in Lite** — the collector, chart, and `get_memory_pressure_events` MCP tool previously only in the Full Edition are now available in Lite ([#865])
- **Grid auto-scrolling** in Lite and Dashboard ([#843]) — thanks [@ClaudioESSilva](https://github.com/ClaudioESSilva)

### Changed

- **PlanAnalyzer and BenefitScorer** synced with PerformanceStudio's Apr 9–16 improvements
- **Query/Procedure/Query Store stats** refactored to a phased DECOMPRESS approach; removed unhelpful `WAITFOR DECOMPRESS` filters
- **Query/Procedure/Query Store grids** capped to TOP 500 to prevent UI freezes on large datasets
- **Server tabs lazy-load** — only the visible server tab loads on startup; remaining tabs load on first visit
- **Webhook URLs (Dashboard)** encrypted with DPAPI via Windows Credential Manager — Lite webhook URLs remain in plaintext settings for now
- **DuckDB queries hardened** — parameterized values, escaped paths, fixed `IsArchiving` race
- **Lite chart axes and sub-tab styling** polished, then ported to Dashboard

### Fixed

- **Memory Pressure Events chart filter** was dropping valid rows; added MCP interpretation guidance ([#865])
- **FinOps recommendation severity sort order** in Lite and Dashboard ([#872])
- **Overview crosshair** disappearing after tab switches or layout passes
- **Blocked process report plan lookup** returning the wrong plan ([#867])
- **FinOps TDE recommendation** flagging Standard edition on SQL Server 2019+ where TDE is free ([#854])
- **Azure SQL DB collector** falls back to single-database mode when `master` is inaccessible ([#857])
- **Azure SQL DB query snapshots** scoped to the current database ([#857])
- **Azure SQL DB query snapshot prefilter** — request set is narrowed into `#temp` before joining DMVs to avoid Azure-specific execution plan issues ([#857])
- **Azure SQL DB live query plans** — now skipped gracefully instead of erroring ([#857])
- **Azure SQL DB memory_stats collector** — dropped `sys.dm_os_schedulers` which is blocked on elastic-pool contained users regardless of DB-scoped grants ([#857])
- **Non-transient permission denials** now stop collector retries instead of looping forever ([#857])

## [2.7.0] - 2026-04-13

### Added

- **Host OS column** in Server Inventory for both Dashboard and Lite ([#748], [#823])
- **Offline community script support** via `community/` directory for user-contributed scripts ([#814], [#822])
- **MultiSubnetFailover connection option** in Dashboard and Lite for Always On availability groups ([#813], [#821])

### Changed

- **PlanAnalyzer and ShowPlanParser** synced from PerformanceStudio with latest improvements ([#816])
- **MCP query tools** optimized for large databases ([#826])
- **Add Server dialog UX** improved with inline connection status and full-height window
- **"CPUs" renamed to "Logical CPUs"** for clarity in Lite ([#825])

### Fixed

- **Dashboard auto-refresh stalling under load** — replaced DispatcherTimer with async Task.Delay loop to prevent priority starvation during heavy chart rendering ([#833], [#834])
- **Lite auto-refresh silently skipping** every tick ([#824])
- **Deadlock count not resetting** between collections ([#803], [#820])
- **Upgrade filter skipping patch versions** during version comparison ([#817], [#819])
- **Upgrade script executing against master** instead of PerformanceMonitor database ([#828])
- **Duplicate release builds** triggering on both created and published events

## [2.6.0] - 2026-04-08

### Added

- **Correlated timeline lanes** on Lite Overview and Dashboard — synchronized CPU, memory, waits, and TempDB trend lanes for at-a-glance correlation ([#688])
- **Dynamic baselines and anomaly detection** in Lite and Dashboard — automatic baseline calculation with anomaly highlighting on key metrics ([#692], [#693])
- **Query grid comparison** — before/after comparison mode for query grids in Lite and Dashboard with global Compare dropdown ([#687])
- **Nonclustered index count badge** on modification operators in plan viewer ([#788])
- **Upgrade detection in Edit Server** dialog — see pending upgrades without adding a new server ([#772])
- **CLI installer interactive mode** prompts for trust-cert and encryption settings ([#784])
- **SignPath code signing** — release binaries are now digitally signed via the [SignPath FOSS](https://signpath.io) program

### Changed

- **PlanAnalyzer Rule 3 (Serial Plan)** comprehensively refined — severity demotion for TRIVIAL and 0ms plans, `CouldNotGenerateValidParallelPlan` treated as actionable, all 25 `NonParallelPlanReason` values now covered
- **PlanAnalyzer warning rules** ported from PerformanceStudio improvements
- **Text readability** — replaced all muted/dim text colors with full foreground colors for readability

### Fixed

- **Embedded resource upgrade discovery** broken — upgrades silently returned zero results for Dashboard installs ([#772])
- **Archive compaction OOM** on large parquet groups
- **CLI installer argument parsing** treating flags as positional args ([#786])
- **Lite long-running query alerts** firing on stale DuckDB snapshots
- **FinOps Enterprise feature detection** now queries all databases and filters to TDE only ([#780])
- **Second launch error** — now brings existing window to foreground instead ([#769])
- **Overview tab Memory Grant** showing 0 for all timestamps ([#776])
- **Lite FinOps Enterprise features** query error on servers without `database_id` column ([#777])
- **Collector health status** incorrect for on-load collectors
- **CSV and clipboard exports** writing `System.Windows.Controls.StackPanel` as column headers instead of actual header text ([#805])

## [2.5.0] - 2026-03-30

### Important

- **InstallerGui retired**: The standalone GUI installer has been removed. Installation, upgrade, and uninstall are now handled directly from the Dashboard's Add Server dialog, powered by the new Installer.Core shared library. The CLI installer continues to work as before. ([#755])

### Added

- **Dashboard integrated installer** — Add Server dialog now installs, upgrades, and uninstalls PerformanceMonitor directly, replacing the standalone InstallerGui ([#755])
- **Installer.Core shared library** — shared installation logic used by both the CLI installer and Dashboard ([#755])
- **Overview tab** for Lite with 2x2 resource chart grid (CPU, Memory, Wait Stats, TempDB) ([#689])
- **Chart drill-down** on CPU, Memory, TempDB, Blocking, and Deadlock charts in both Dashboard and Lite — right-click any chart point to jump to Active Queries for that time window ([#682])
- **Grid-to-slicer overlay** for Query Stats, Procedure Stats, and Query Store tabs — click a row to overlay its trend on the slicer chart ([#683])
- **Query heatmap** tab in both Dashboard and Lite — visual heat map of query activity over time ([#739], [#743])
- **Webhook notifications** for alerts — configurable webhook endpoint for alert delivery ([#725])
- **Per-server collector schedule intervals** — customize collection frequency per server ([#703])
- **Investigate button** in Critical Issues grid — jump directly to relevant tab from an alert ([#684])
- **Dismiss Selected** context menu and View Log sidebar button for alert management ([#718], [#740])
- **Alert archival awareness** — dismissed_archive_alerts sidecar table, source column for live vs archived alerts, stale-data indicator, structured telemetry ([#718])
- **Dashboard read-only connection intent** — connections use `ApplicationIntent=ReadOnly` where supported ([#728])
- FUNDING.yml for GitHub Sponsors ([#752])

### Changed

- **Installer architecture** refactored: CLI installer is now a thin wrapper over Installer.Core ([#755])
- **DuckDB memory capped** at 2 GB during parquet compaction to prevent out-of-memory on large archives ([#758])
- **Text rendering** improved with `TextOptions.TextFormattingMode="Display"` for sharper text ([#710])
- **installation_history version columns** widened from nvarchar(255) to nvarchar(512) to handle long @@VERSION strings ([#712])

### Fixed

- **Memory leaks in Lite** — delta cache, event handlers, and chart helpers properly disposed ([#758])
- **Doomed transaction errors** in delta framework and ensure_collection_table — ROLLBACK now occurs before error logging ([#756])
- **XACT_STATE check** added after third-party stored procedure calls (sp_HumanEventsBlockViewer, sp_BlitzLock) to prevent doomed transaction errors ([#695])
- **CREATE DATABASE failure** when model database has large default file sizes ([#676])
- **CPU metrics mixed** for different Azure SQL databases on the same logical server ([#680])
- **Azure SQL DB vCore** FinOps calculations incorrect for serverless/vCore tiers ([#736])
- **Webhook alert recording** not persisting correctly ([#726])
- **Drill-down timezone** misalignment between chart and detail view ([#747], [#750])
- **Drill-down refresh** losing context on auto-refresh ([#744])
- **Drill-down target** incorrectly routing Memory to Memory Grants instead of Active Queries ([#706])
- **Heatmap colorbar stacking** when switching between servers ([#746])
- **Display mode pickers** not reflecting current state on tab switch ([#751])
- **Slicer custom range** handling and sub-hour display issues ([#704])
- **Overlay selection** lost on Dashboard auto-refresh ([#683])
- **Numeric values** in alert details treated as strings instead of numbers ([#732])
- **FinOps VM right-sizing** query error — `PERCENTILE_CONT` missing required `OVER()` clause
- **FinOps Enterprise features** query error on AWS RDS — `database_id` column not present in `sys.dm_db_persisted_sku_features` on RDS
- **FinOps right-click copy** broken on all Dashboard FinOps grids — context menu walked to row instead of grid
- **FinOps recommendation error logs** now include server name for easier troubleshooting

### Deprecated

- **InstallerGui** — removed from the solution and build pipeline. Use the Dashboard or CLI installer instead. ([#755])

## [2.4.0] - 2026-03-23

### Important

- **Lite data directory moved**: Lite now stores all data (config, DuckDB, archives, logs) in `%LOCALAPPDATA%\PerformanceMonitorLite\` instead of alongside the executable. This enables auto-update support. Existing users upgrading from the zip should use **Import Settings** and **Import Data** to bring over their configuration and historical data from the old install folder.
- **Auto-update (Windows)**: Both Dashboard and Lite now include Velopack auto-update. Users who install via the new Setup.exe will receive update notifications and can download + apply updates from within the app. Existing zip distribution continues to work as before.

### Added

- **Velopack auto-update** for Dashboard and Lite — check on startup, download + apply from About window with confirmation dialog before restart ([#635])
- **Per-tab time range slicers** on Dashboard and Lite query tabs — filter data directly on each tab without changing global time range ([#655], [#662])
- **Time display picker** (Local/UTC/Server) in Dashboard and Lite toolbars ([#646])
- **Import Settings** — renamed from "Import Connections", now also copies `settings.json`, `collection_schedule.json`, `ignored_wait_types.json`, and `alert_state.json` from a previous install
- **Alert muting improvements** — pre-fill context fields (database, query, wait type, job name) from alert detail text, configurable default expiration for new mute rules, tooltip on query text field ([#642])
- **Missing date columns** on Query Stats and Procedure Stats tabs (`creation_time`, `last_execution_time`) ([#649], [#651], [#654])
- **Trace pattern drill-down** now includes `CollectionTime` and `NtUserName` columns ([#663])
- **DataGrid sort preservation** across auto-refresh — sort order no longer resets when data refreshes ([#659])
- **CLI installer**: colored output (green/red/yellow) and version check on startup ([#639])
- **GUI installer**: version check on startup
- **Growth rate and VLF count** columns in Database Sizes (from v2.3.0 nightly, now in upgrade path) ([#567])
- `llms.txt` and `CITATION.cff` for project discoverability ([#630])

### Changed

- **Lite data directory** moved to `%LOCALAPPDATA%\PerformanceMonitorLite\` for Velopack compatibility
- **Delta gap detection** added to all cumulative-counter collectors (file I/O, wait stats, query stats, procedure stats, memory grants) — prevents inflated spikes after app restart ([#633])
- **File I/O NULL fallbacks** improved when `sys.master_files` is inaccessible — falls back to `DB_NAME()` and `File_{id}` instead of generic "Unknown" ([#633])
- **Running jobs collector** skipped gracefully when login lacks msdb access ([#656])
- NuGet packages updated to latest minor versions ([#653])

### Fixed

- **Installer writing SUCCESS when files fail** — CLI tolerated 1 failure in automated mode, GUI had a similar workaround. Now any failure = not success.
- **Query stats collector causing SQL dumps** on passive mirror servers — removed `dm_exec_plan_attributes` CROSS APPLY, uses temp table of ONLINE database IDs instead ([#632])
- **Trigger name extraction** fails when comment before `CREATE TRIGGER` contains " ON " ([#666])
- **FinOps expensive queries** DuckDB error — query referenced `statement_start_offset` column that doesn't exist in schema
- **Imported parquet files** not recognized by archive compaction — added regex patterns for `imported_` prefix
- **Auto-refresh after Import Data** — views now refresh immediately after import completes

## [2.3.0] - 2026-03-18

### Important

- **Schema upgrade**: Six columns widened across three tables (`query_stats`, `cpu_scheduler_stats`, `waiting_tasks`, `database_size_stats`) to match DMV documentation types. These are in-place ALTER COLUMN operations — fast on any table size, no data migration. Upgrade scripts run automatically via the CLI/GUI installer.
- **SQL Server version check**: Both installers now reject SQL Server 2014 and earlier before running any scripts, with a clear error message. Azure MI (EngineEdition 8) is always accepted. ([#543])
- **Installer adversarial tests**: 35 automated tests covering upgrade failures, data survival, idempotency, version detection fallback, file filtering, restricted permissions, and more. These run as part of pre-release validation. ([#543])

### Added

- **ErikAI analysis engine** — rule-based inference engine for Lite that scores server health across wait stats, CPU, memory, I/O, blocking, tempdb, and query performance. Surfaces actionable findings with severity, detail, and recommended actions. Includes anomaly detection (baseline comparison for acute deviations), bad actor detection (per-query scoring for consistently terrible queries), and CPU spike detection for bursty workloads. ([#589], [#593])
- **ErikAI Dashboard port** — full analysis engine ported to Dashboard with SQL Server backend ([#590])
- **FinOps cost optimization recommendations** — Phase 1-4 checks: enterprise feature audit, CPU/memory right-sizing, compression savings estimator, unused index cost quantification, dormant database detection, dev/test workload detection, VM right-sizing, storage tier optimization, reserved capacity candidates ([#564])
- **FinOps High Impact Queries** — 80/20 analysis showing which queries consume the most resources across all dimensions ([#564])
- **FinOps dollar-denominated cost attribution** — per-server monthly cost setting with proportional database-level breakdown ([#564])
- **On-demand plan fetch** for bad actor and analysis findings — click to retrieve execution plans for flagged queries ([#604])
- **Plan analysis integration** — findings include execution plan analysis when plans are available ([#594])
- **Server unreachable email alerts** — Dashboard sends email (not just tray notification) when a monitored server goes offline or comes back online ([#529])
- **Column filters on all FinOps DataGrids** — filter funnel icons on every column header across all 7 FinOps grids in Lite and Dashboard ([#562])
- **Column filters on Dashboard** IdleDatabases, TempDB, and Index Analysis grids
- **Lite data import** — "Import Data" button brings in monitoring history from a previous Lite install via parquet files, preserving trend data across version upgrades ([#566])
- **Per-server Utility Database setting** — Lite can call community stored procedures (sp_IndexCleanup) from a database other than master ([#555])
- **SQL Server version check** in both CLI and GUI installers — rejects 2014 and earlier with a clear message ([#543])
- **Execution plan analysis MCP tools** for both Dashboard and Lite
- **Full MCP tool coverage** — Dashboard expanded from 28 to 57 tools, Lite from 32 to 51 tools ([#576], [#577])
- **Self-sufficient analyze_server drill-down** — MCP tool returns complete analysis, not breadcrumb trail ([#578])
- **NuGet package dependency licenses** in THIRD_PARTY_NOTICES.md

### Changed

- **Azure SQL DB FinOps** — all collectors (database sizes, query stats, file I/O) now connect to each database individually instead of only querying master. Server Inventory uses dynamic SQL to avoid `sys.master_files` dependency. ([#557])
- **Index Analysis scroll fix** — both summary and detail grids now use proportional heights instead of Auto, so they scroll independently with large result sets ([#554])
- **Dashboard Add Server dialog** — increased MaxHeight from 700 to 850px so buttons are visible when SQL auth fields are shown
- **GUI installer** — Uninstall button now correctly enables after a successful install
- **GUI installer** — fixed encryption mapping and history logging ([#612])
- **Dashboard visible sub-tab only refresh** on auto-refresh ticks ([#528])
- Analysis engine decouples data maturity check from analysis window

### Fixed

- **Installer dropping database on every upgrade** — `00_uninstall.sql` excluded from install file list, installer aborts on upgrade failure, version detection fallback returns "1.0.0" instead of null ([#538], [#539])
- **SQL dumps on mirroring passive servers** from FinOps collectors ([#535])
- **RetrievedFromCache** always showing False ([#536])
- **Arithmetic overflow** in query_stats collector for dop/thread columns ([#547])
- **Lite perfmon chart bugs** and Dashboard ScottPlot crash handling ([#544], [#545])
- **PLE=0 scoring bug** — was scored as harmless, now correctly flagged ([#543])
- **PercentRank >1.0** bug in HealthCalculator
- **6 verified Lite bugs** from code review ([#611])
- **Enterprise feature audit text** — partitioning is not Enterprise-only
- **FinOps collector scheduling**, server switch, and utilization bugs
- **Dashboard drill-down** Unicode arrow in story path split
- **Empty DataGrid scrollbar artifacts** — hide grids when empty across all FinOps tabs
- **Query preview** — truncated in row, full text in tooltip

## [2.2.0] - 2026-03-11

**Contributors:** [@HannahVernon](https://github.com/HannahVernon), [@ClaudioESSilva](https://github.com/ClaudioESSilva), [@dphugo](https://github.com/dphugo), [@Orestes](https://github.com/Orestes) — thank you!

### Important

- **Schema upgrade**: Three large collection tables (`query_stats`, `procedure_stats`, `query_store_data`) are migrated to use `COMPRESS()` for query text and plan columns. The upgrade performs a table swap (create new → migrate data → rename) which may take several minutes on large tables. A `row_hash` column is added for deduplication. Three new tracking tables are also created. Volume stats columns are added to `database_size_stats`. Upgrade scripts run automatically via the CLI/GUI installer and use idempotent checks.

  Compression results measured on a production instance:

  | Table | Compressed | Uncompressed | Ratio |
  |---|---|---|---|
  | query_stats | 18.0 MB | 339.0 MB | 18.8x |
  | query_store_data | 13.5 MB | 258.0 MB | 19.1x |
  | **Total** | **31.5 MB** | **597 MB** | **~19x** |

### Added

- **FinOps monitoring tab** — database size tracking, server properties, storage growth analysis (7d/30d), index analysis with unused/duplicate/compressible detection, utilization efficiency, idle database identification, and estate-level resource views ([#474])
- **Named collection presets** — Aggressive, Balanced, and Low-Impact schedule profiles via `config.apply_collection_preset` ([#454])
- **Entra ID interactive MFA authentication** in both CLI and GUI installers for Azure SQL MI connections ([#481])
- **MCP port validation** — TCP port conflict detection, range validation (1024+), Auto port button, and auto-restart on settings change ([#453])
- **Alert database exclusion filters** — filter blocking and deadlock alerts by database in both Dashboard and Lite ([#410], [#412])
- **Configurable alert cooldown periods** for tray notifications and email alerts
- **Wait stats query drill-down** — click a wait type to see the queries causing it ([#372])
- **Configurable long-running query settings** — max results, WAITFOR/backup/diagnostics exclusions ([#415])
- **Uninstall option** in both CLI and GUI installers ([#431])
- **Session stats collector** for active session tracking ([#474])
- **LOB compression and deduplication** for query stats tables to reduce storage ([#419])
- **Volume-level drive space** enrichment in database size stats via `dm_os_volume_stats`
- **GUI installer installation history** logging to `config.installation_history` ([#414])
- **ReadOnlyIntent connection option** — Lite connections can set `ApplicationIntent=ReadOnly` for automatic read routing to Always On AG readable secondaries ([#515])
- **Alert muting** — mute individual alerts or create pattern-based mute rules by server, metric, database, or application. Manage Mute Rules window with enable/disable toggle. Alert history detail view with double-click drill-down and context-sensitive detail text. Poison wait type documentation links. ([#512])
- **SignPath code signing** — all release binaries (Dashboard, Lite, Installers) are digitally signed, eliminating Windows SmartScreen warnings ([#511])
- CI version bump check on PRs to main
- Permissions section in README with least-privilege setup ([#421])

### Changed

- **Utilization tab redesigned** — ported to Dashboard with aligned metrics between apps ([#478])
- PlanAnalyzer rules synced from PerformanceStudio — Rule 5 message format, seek predicate parsing, spool labels, unmatched index detail ([#416], [#475], [#480])
- Data retention now purges processed XE staging rows
- GeneratedRegex conversion for compile-time regex patterns ([#346], [#420])
- Server health card width increased from 260 to 300 for less text truncation ([#489])
- User's locale used for date/time formatting in WPF bindings ([#459])
- XML processing instructions stripped from sql_command/sql_text display
- Parameterized queries in blocking/deadlock alert filtering
- **DuckDB 1.5.0 upgrade** — non-blocking checkpointing eliminates read stalls during WAL flushes, free block reuse stabilizes database file size without archive-and-reset cycles ([#516])
- **Automatic parquet compaction** — archive files are merged into monthly files after each archive cycle, reducing file count from 2,600+ to ~75 and eliminating per-file metadata overhead on glob scans ([#516])

  Combined with the UI responsiveness overhaul (#510), Lite's refresh cycle improved 13-26x:

  | Metric | Before | After |
  |---|---|---|
  | Lite `RefreshAllDataAsync` | 6-13s | < 500ms |
  | Parquet files scanned per query | 233 | 19 |
  | Archive-and-reset frequency | 21/day | ~0 |
  | `v_wait_stats` query time | 1,700ms | 27ms |

- **Monthly archive retention** — switched from 90-day file-age deletion to 3-month calendar-month rolling window, aligned with compacted monthly filenames ([#516])
- **Lite status bar** shows used data size vs file size (e.g., "Database: 175.5 / 423.8 MB") via DuckDB `pragma_database_size()` ([#517])
- **Query Store collector diagnostics** — reader/append/flush timing breakdown logged when collection exceeds 2 seconds, for identifying SQL Server DMV contention under heavy workloads ([#518])
- SSMS-parity edge tooltips on plan viewer operator connections and ManyToMany indicator always shown for merge join operators ([#504])
- **Lite UI responsiveness overhaul** — visible-tab-only refresh, sub-tab awareness, Query Store collector optimization (NULL plan XML + LOOP JOIN hint), and DuckDB write reduction ([#510])

  Timer tick improvements measured under TPC-C load on SQL2022:

  | Scenario | Before | After | Improvement |
  |---|---|---|---|
  | Lite idle | 6-13s | 546-750ms | ~90% |
  | Lite under TPC-C | 6-13s | ~3s | ~70% |
  | Dashboard idle | 5.6s | 0.6-0.8s | 86% |
  | Dashboard under TPC-C | 5.6s | 1.8-2.0s | 64% |

  Query Store collector specifically:

  | Metric | Before | After |
  |---|---|---|
  | query_store collector total | 6-18s | ~600ms |
  | query_store SQL time | 374-1,104ms | ~300ms (LOOP JOIN hint) |
  | query_store DuckDB write | 6-16s | ~75-230ms (NULL plan XML) |

### Fixed

- **UI hang** when opening Dashboard tab for offline server — replaced synchronous `.GetAwaiter().GetResult()` with proper `await` ([#477])
- **First-collection spike** skewing PerfMon, wait stats, file I/O, memory grant, query stats, and procedure stats charts — first cumulative value now treated as baseline ([#482])
- **Wait type filter TextBox** too small to read ([#488])
- **Poison wait false positives** and alert log parsing ([#445], [#448])
- **RID Lookup** analyzer rule matching new PhysicalOp label ([#429])
- **procedure_stats** plan query using DECOMPRESS after compression migration
- **database_size_stats** InvalidCastException on compatibility_level
- **Deadlock filter** using wrong column reference in `GetFilteredDeadlockCountAsync`
- **RESTORING database** filter added to waiting_tasks collector ([#430])
- Custom TrayToolTip crash — replaced with plain ToolTipText ([#422])
- **Lite tab switch freeze** — added `_isRefreshing` guard to prevent tab switch handler from competing with timer ticks for DuckDB connection, eliminating "not responding" hangs ([#510])
- DuckDB read lock acquisition resilience
- Formatted duration columns sorting alphabetically instead of numerically
- Settings window staying open on validation errors
- Deserialization clamping and validation abort issues
- **sp_IndexCleanup** summary grid column mapping off-by-one, expanded both grids to show all columns from both result sets ([#503])
- **Rule 22 table variable** false positive on modification operators — INSERT/UPDATE/DELETE on table variables is expected ([#513])
- **ComboBox focus steal** in plan viewer stealing keyboard focus from other controls ([#508])
- **DOP 2 skew** false positive — parallel skew rule no longer fires at DOP 2 ([#508])
- **ReadOnlyIntent connections** sharing server_id in DuckDB when the same server was added with and without ReadOnlyIntent ([#521])

[2.2.0]: https://github.com/erikdarlingdata/PerformanceMonitor/compare/v2.1.0...v2.2.0

## [2.1.0] - 2026-03-04

### Important

- **Schema upgrade**: The `config.collection_schedule` table gains two new columns (`collect_query`, `collect_plan`) for optional query text and execution plan collection. Both default to enabled to preserve existing behavior. Upgrade scripts run automatically via the CLI/GUI installer and use idempotent checks.

### Added

- **Light theme and "Cool Breeze" theme** — full light mode support for both Dashboard and Lite with live preview in settings ([#347])
- **Standalone Plan Viewer** — open, paste (Ctrl+V), or drag & drop `.sqlplan` files independent of any server connection, with tabbed multi-plan support ([#359])
- **Time display mode toggle** — show timestamps in Server Time, Local Time, or UTC with timezone labels across all grids and tooltips ([#17])
- **30 PlanAnalyzer rules** — expanded from 12 to 30 rules covering implicit conversions, GetRangeThroughConvert, lazy spools, OR expansion, exchange spills, RID lookups, and more ([#327], [#349], [#356], [#379])
- **Wait stats banner** in plan viewer showing top waits for the query ([#373])
- **UDF runtime details** — CPU and elapsed time shown in Runtime Summary pane when UDFs are present ([#382])
- **Sortable statement grid** and canvas panning in plan viewer ([#331])
- **Comma-separated column filters** — enter multiple values separated by commas in text filters ([#348])
- **Optional query text and plan collection** — per-collector flags in `config.collection_schedule` to disable query text or plan capture ([#337])
- **`--preserve-jobs` installer flag** — keep existing SQL Agent job schedules during upgrade ([#326])
- **Copy Query Text** context menu on Dashboard statements grid ([#367])
- **Server list sorting** by display name in both Dashboard and Lite ([#30])
- **Warning status icon** in server health indicators ([#355])
- Reserved threads and 10 missing ShowPlan XML attributes in plan viewer ([#378])
- Nightly build workflow for CI ([#332])

### Changed

- PlanAnalyzer warning messages rewritten to be actionable with expert-guided per-rule advice ([#370], [#371])
- PlanAnalyzer rule tuning: time-based spill analysis (Rule 7), lowered parallel skew thresholds (Rule 8), memory grant floor raised to 1GB/4GB (Rule 9), skip PROBE-only bitmap predicates (Rule 11) ([#341], [#342], [#343], [#358])
- First-run collector lookback reduced from 3-7 days to 1 hour for faster initial data ([#335])
- Plan canvas aligns top-left and resets scroll on statement switch ([#366])
- Plan viewer polish: index suggestions, property panel improvements, muted brush audit ([#365])
- Add Server dialog visual parity between Dashboard and Lite with theme-driven PasswordBox styling ([#289])

### Fixed

- **OverflowException** on wait stats page with large decimal values — SQL Server `decimal(38,24)` exceeding .NET precision ([#395])
- **SQL dumps** on mirroring passive servers with RESTORING databases ([#384])
- **UI hang** when adding first server to Dashboard ([#387])
- **UTC/local timezone mismatch** in blocked process XML processor ([#383])

- UDF timing units corrected: microseconds to milliseconds ([#338])
- DuckDB migration ordering after archive-and-reset ([#314])
- Int16 cast error in long-running query alerts ([#313])
- Missing dark mode on 19 SystemEventsContent charts ([#321])
- Missing tooltips on charts after theme changes ([#319])
- Operator time per-thread calculation synced across all plan viewers ([#392])
- Theme StaticResource/DynamicResource binding fix for runtime theme switching
- Memory grant MB display, missing index quality scoring, wildcard LIKE detection ([#393])
- **Installer validation** reporting historical collection errors as current failures — now filters to current run only ([#400])

- **Missing upgrade script** for `default_trace_events` columns (`duration_us`, `end_time`) on 2.0.0→2.1.0 upgrade path ([#400])

## [2.0.0] - 2026-02-25

### Important

- **Schema upgrade**: The `collect.memory_grant_stats` table gains new delta columns and drops unused warning columns. The `collect.session_wait_stats` table, its collector procedure, reporting view, and schedule entry are removed (zero UI coverage). Upgrade scripts run automatically via the CLI/GUI installer and use idempotent checks.

### Added

- **Graphical query plan viewer** — native ShowPlan rendering in both Dashboard and Lite with SSMS-parity operator icons, properties panel, tooltips, warning/parallelism badges, and tabbed plan display ([#220])
- **Actual execution plan support** — execute queries with SET STATISTICS XML ON to capture actual plans, with loading indicator and confirmation dialog ([#233])

- **Current Active Queries live snapshot** — real-time view of running queries with estimated/live plan download ([#149])
- **Memory clerks tab** in Lite with picker-driven chart ([#145])
- **Current Waits charts** in Blocking tab for both Dashboard and Lite ([#280])
- **File I/O throughput charts** — read/write throughput trends, file-level latency breakdown, queued I/O overlay ([#281])
- **Memory grant stats charts** — standardized collection with delta framework integration and trend visualization ([#281])
- **CPU scheduler pressure status** — real-time scheduler, worker, runnable task counts with color-coded pressure level below CPU chart
- **Collection log drill-down** and daily summary in Lite ([#138])
- **Collector duration trends chart** in Dashboard Collection Health ([#138])
- **Themed perfmon counter packs** — 14 new counters with organized themed groups ([#255])
- **User-configurable connection timeout** setting ([#236])
- **Per-collector retention** — uses per-collector retention from `config.collection_schedule` in data retention ([#237])
- **Query identifiers** in drill-down windows — query hash, plan hash, SQL handle visible for identification ([#268])
- **Trace pattern drill-down** with missing columns and query text tooltips ([#273])
- **Query Store Regressions drill-down** with TVF rewrite for performance ([#274])
- **CLI `--help` flag** for installer ([#111])
- Sort arrows, right-aligned numerics, and initial sort indicators across all grids ([#110])
- Copyable plan viewer properties ([#269])
- Standardized chart save/export filenames between Dashboard and Lite ([#284])
- Full Dashboard column parity for query_stats, procedure_stats, and query_store_stats
- Min/max extremes surfaced in both apps — physical reads, rows, grant KB, spills, CLR time, log bytes ([#281])

### Changed

- Query Store detection uses `sys.database_query_store_options` instead of `sys.databases.is_query_store_on` for Azure SQL DB compatibility ([#287])
- Config tab consolidation, DB drop on server remove, DuckDB-first plan lookups, procedure stats parity
- Collector health status now detects consecutive recent failures — 5+ consecutive errors = FAILING, 3+ = WARNING
- Plan buttons now show a MessageBox when no plan is available instead of silently doing nothing
- CSV export uses locale-appropriate separators for non-US locales ([#240])
- Query Store Regressions and Query Trace Patterns migrated to popup grid filtering ([#260])
- NuGet packages updated; xUnit v3 migration

### Fixed

- **DuckDB file corruption** during maintenance — ReaderWriterLockSlim coordination, archive-all-and-reset at 512MB replaces compaction ([#218])
- Archive view column mismatch, wait_stats thread-safety, and percent_complete type cast ([#234])
- Collector health status bar text color ([#234])
- View Plan for Query Store and Query Store Regressions tabs ([#261])
- Query Store drill-down time filter alignment with main view ([#263])
- Execution count mismatches between main views and drill-downs
- Drill-down chart UX — sparse data markers, hover tooltips, window sizing ([#271])
- Truncated status text in Add Server dialog ([#257])
- Scrollbar visibility, self-filtering artifacts, missing columns, and context menus ([#245], [#246], [#247], [#248])
- query_stats and procedure_stats collectors ignoring recent queries
- Blank tooltips on warning and parallel badge icons
- Missing chart context menu on File I/O Throughput charts in Lite

### Removed

- `collect.session_wait_stats` table, `collect.session_wait_stats_collector` procedure, `report.session_wait_analysis` view, and schedule entry — zero UI coverage, never surfaced in Dashboard or Lite ([#281])

## [1.3.0] - 2026-02-20

### Important

- **Schema upgrade**: The `collect.memory_stats` table gains two new columns (`total_physical_memory_mb`, `committed_target_memory_mb`). The upgrade script runs automatically via the CLI/GUI installer and uses `IF NOT EXISTS` checks, so it is safe to re-run. On servers with very large `memory_stats` tables this ALTER may take a moment.

### Added
