 ## [Unreleased]
 
+## [0.2.0] - 2026-07-12
+
+### Added
+
+- **Contribution history store (SQLite)** — `ContributionStore` persists each provider's daily counts in `var/data/contributions.db`; `ContributionAggregator` now fetches only the window since each provider's last stored date (plus a 3-day trailing overlap for late corrections), merges the result into the store, and prunes rows older than `CONTRIBUTIONS_RETENTION_DAYS`
+- **`graph:contributions:refetch` console command** — forces a full or explicit-range re-fetch of contribution history, chunked into ≤365-day windows, for one, several, or all configured providers
+- **Concurrent, non-blocking provider fetches** — `ProviderInterface::fetch()` split into `startFetch()`/`resolveFetch()` so GitHub, GitLab, and Gitea requests are in flight simultaneously instead of one after another
+- **Bounded fetch windows** — `startFetch()`/`resolveFetch()` accept optional `$since`/`$until` bounds, used by both the incremental aggregator and the refetch command
+- **PHPStan static analysis** — level 8 over `src/` and `tests/`, run via `composer phpstan`
+- `Contribution` and `ContributionCollection` typed entities
+- `CONTRIBUTIONS_RETENTION_DAYS` environment variable
+
+### Changed
+
+- **Namespace renamed from `App` to `GitContributionGraph`** across the codebase, Composer autoloading, and routing config
+- Removed the Guzzle and GraphQL client bundles — GitHub requests now go through Symfony's `HttpClientInterface` directly, the same as GitLab and Gitea
+- HTTP client requests are capped (10s connect/first-byte timeout, 15s max duration) so a slow provider can no longer stall the render path
+- `docker-compose.yml` and `docker-compose.prod.yml` mount a `data` volume for the SQLite store and pass through `CONTRIBUTIONS_RETENTION_DAYS`
+- Dev Docker Compose override targets the `dev` build stage explicitly and mounts `vendor` read-write instead of as an anonymous volume
+
+### Fixed
+
+- `ContributionCollection`'s variadic constructor now re-indexes its arguments with `array_values()`, avoiding non-sequential keys that didn't match its declared property type
+- `SvgRenderer` coerces `strtotime()` results to `int` before formatting dates
+- `docker-compose.prod.yml` was missing the `data` volume and `CONTRIBUTIONS_RETENTION_DAYS` env var present in `docker-compose.yml`, so contribution history would not survive a container recreate on that deployment path
+- `composer phpstan` no longer crashes with an out-of-memory error under the default 128M limit
+
+### Documentation
+
+- README and `CLAUDE.md` updated to describe the SQLite store, incremental fetch, refetch command, and PHPStan setup; corrected several stale examples (test path, `/health` sample response, Docker volume mounts)
+- Added PHPDoc to the remaining public methods across `src/`
+
+### Tests
+
+- Added tests for `ContributionStore`, `Contribution`, `ContributionCollection`, and `RefetchContributionsCommand`
+- Extended provider and aggregator tests to cover `$since`/`$until` windowing, concurrent-fetch failure modes, and store interactions
+
