# Omnigraph v0.3.1

Omnigraph v0.3.1 is a performance and operability point release.

## Highlights

- **Parallel per-type load writes**: the bulk loader writes to each node/edge table concurrently rather than serially, materially reducing wall-clock time on multi-table loads.
- **`omnigraph optimize` and `omnigraph cleanup` CLI commands**: previously only available via the engine API. `optimize` runs Lance `compact_files()` across every node/edge table; `cleanup` runs Lance `cleanup_old_versions()` with a `--keep`/`--older-than` policy and requires `--confirm` for the destructive form.
- **Dst-id deduplication during edge expand hydration**: avoids redundant lookups when the same destination id appears multiple times in an `Expand` step (#45).

## Included Changes

- Parallel per-type load writes (#46)
- `omnigraph optimize` / `cleanup` CLI commands and runtime APIs (#46)
- Dedupe dst ids before hydrating nodes in `execute_expand` (#45)

## Upgrade Notes

No breaking changes. Existing v0.3.0 repos can be opened directly with v0.3.1.
