# Coder Studio v0.4.0

## Why this release matters

`v0.4.0` is a substantial workflow and platform update. It gives Coder Studio more control over how language-server support runs, removes the remaining SQLite-era runtime persistence path in favor of the newer file-backed model, and tightens supervisor restore and editing flows across desktop and mobile.

In practice, this release means:

- language-server runtime behavior is now configurable, including managed installation flows for supported runtimes
- workspace, terminal, auth, settings, provider config, and supervisor persistence no longer depend on the retired SQLite compatibility layer
- supervisor sessions restore more reliably after reconnects or restarts, with clearer edit and recovery flows
- UI foundations for overlays, spacing, typography, and session-state visibility are more consistent across desktop and mobile

## Included in v0.4.0

- add configurable LSP runtime behavior and managed language-server installation support
- remove the remaining SQLite runtime compatibility chain and move persistence onto the newer file-backed repositories
- improve supervisor restore, edit, decomposition, and details-first workflows across desktop and mobile
- tighten running-session visibility and session-state feedback in the workspace shell
- unify overlay, drawer, and modal foundations so shared surfaces behave more consistently
- ship a broad pass of web polish and regression fixes around diagnostics, settings, mobile session flows, and supervisor layout

## Who benefits most

- users relying on Monaco + LSP support inside the browser workspace
- developers reopening long-lived workspaces and expecting supervisor state to restore cleanly
- teams evaluating Coder Studio for steadier day-to-day use beyond early prototype flows
- contributors who need the runtime and persistence model to be easier to reason about and maintain

## Install or upgrade
