+## [0.5.0b0] - 2026-06-24
+
+### Added
+
+- **Flask adapter** (`[flask]` optional extras group) — adds a `FlaskRenderer`
+  (Jinja2-backed; share the app's `jinja_env` for consistent filters, globals,
+  and extensions) and a synchronous component endpoint exposed as a Flask
+  blueprint (`POST /components/<name>` via `register_component_routes(app)` or
+  `create_component_blueprint()`). Parses JSON and HTMX form-encoded bodies and
+  returns JSON `404`/`400`/`500` errors. The `[flask]` extra pulls only
+  `flask>=3.0` — no FastAPI/Django/JinjaX. See `examples/flask_example.py`.
+- **Optimistic UI patching in the client** — `component-client.js` now applies
+  an optimistic patch synchronously before the request completes, reading
+  `data-optimistic` JSON / `data-optimistic-toggle` from the trigger element and
+  rolling back when the server response arrives. Ships an accompanying
+  `component-framework.css` with `[data-loading]` / `[data-optimistic]` hooks
+  (reduced-motion aware) and updated `component-client.d.ts` typings.
+- **Sharing an existing JinjaX catalog** — documented and clarified that
+  `JinjaxRenderer` should be constructed with the application's existing
+  `Catalog` so component templates inherit host globals and filters, rather than
+  a fresh, empty catalog.
+
+### Changed
+
+- `[all]` and `[dev]` extras groups now include the `flask` extra.
+
+## [0.4.1b0] - 2026-06-23
+
+### Fixed
+
+- FastAPI and Litestar adapters now accept form-encoded (HTMX default)
+  `POST` bodies in addition to JSON.
+- CI: `ty`'s `invalid-method-override` diagnostic is treated as a warning to
+  accommodate Django's CBV/consumer signature narrowing.
+
+## [0.4.0b0] - 2026-03-01
+
+### Added
+
+- **Litestar adapter** (`[litestar]` optional extras group) — HTTP, WebSocket,
+  and SSE support.
+- **Async event handlers** — `async_dispatch()` / `async_handle_event()` for
+  adapters running in an async context.
+- **SSE streaming** — `StreamingComponent` with async-generator handlers for
+  progressive rendering.
+- **State size guard** — configurable warning at 64 KB and a hard limit at
+  512 KB on serialised component state.
+
+### Fixed
+
+- JS double-serialisation fix in `component-client.js`.
+
