See [documentation](https://github.com/googleapis/release-please#release-please). <!-- CURSOR_SUMMARY --> --- > [!NOTE] > **Medium Risk** > Primarily a release/version bump, but it publishes **breaking API changes** (move to unified `Runner.run()`/`RunnerResult` and removal of `invoke_*` methods), which can break downstream integrations. > > **Overview** > Cuts a new release across the core SDK and provider packages: `launchdarkly-server-sdk-ai` to `0.19.0`, LangChain provider to `0.6.0`, and OpenAI provider to `0.5.0`, updating the release manifest and package metadata accordingly. > > Changelogs document the shipped breaking API surface changes (notably removing `invoke_model()`/`invoke_structured_model()` in favor of `run(...)` and standardizing returns on `RunnerResult`) plus accompanying feature/fix entries; the core package version constants/docs (`__version__`, `PROVENANCE.md`) are updated to match. > > <sup>Reviewed by [Cursor Bugbot](https://cursor.com/bugbot) for commit a20d7a5.
