+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [0.3.0b0] - 2026-02-23
+
+### Breaking Changes
+
+- **`fastapi`, `uvicorn`, and `jinjax` are no longer installed by default.**
+  These packages have been moved from mandatory core dependencies to the optional
+  `[fastapi]` extras group. Existing FastAPI users must update their install command:
+
+  ```bash
+  # Before (0.2.x)
+  pip install component-framework
+
+  # After (0.3.0+)
+  pip install "component-framework[fastapi]"
+  ```
+
+  **CI pipelines** that install the bare package without specifying an extras group
+  will break silently after this upgrade. Update all install commands in CI
+  configuration files (GitHub Actions, Dockerfile, tox.ini, Makefile, etc.).
+
+  **Transitive dependents** — downstream projects that relied on `fastapi` or
+  `jinjax` being pulled in transitively through this library will also be affected.
+  Audit your dependency tree if you see unexpected ImportError messages after upgrading.
+
+### Added
+
+- `[fastapi]` optional extras group — installs `fastapi>=0.109.0`,
+  `uvicorn[standard]>=0.27.0`, and `jinjax>=0.41`.
+- `[dev-base]` optional extras group — test tooling without adapter extras,
+  used by the CI isolation matrix.
+- `[all]` convenience extras group — installs all runtime extras
+  (`[fastapi,django,websockets]`).
+- Actionable `ImportError` messages on all adapter modules — attempting to import
+  an adapter without its extras group now raises a clear error naming the missing
+  package and the install command needed to resolve it. Example:
+
+  ```
+  ImportError: 'fastapi' is not installed.
+  Install the 'fastapi' extra: pip install 'component-framework[fastapi]'
+  ```
+
+- CI extras isolation matrix — each extras group (`base`, `fastapi`, `django`,
+  `all`) is now tested in isolation to prevent cross-adapter contamination.
+- `pytest.importorskip` guards on all adapter test modules — adapter tests skip
+  cleanly instead of failing with `ImportError` when the relevant extras group is
+  not installed.
+
+### Changed
+
+- `[dev]` extras group now self-references all runtime extras via
+  `component-framework[dev-base,fastapi,django,websockets]`. Installing `.[dev]`
+  continues to provide the full development environment.
+- `pydantic>=2.0` is now the only mandatory runtime dependency.

 ## Development Status
 
-**Current Version:** 0.2.0-beta
+**Current Version:** 0.3.0-beta
 **API Documentation:** [fsecada01.github.io/component-framework](https://fsecada01.github.io/component-framework/)
 
 The framework has a complete, tested feature set covering the full Beta roadmap. APIs are solidifying — the core lifecycle, permissions, composition, and testing utilities are stable. We welcome feedback before the 1.0 release.

+## Adapter Support
+
+| Framework | Status | Install extra | Notes |
+|-----------|--------|---------------|-------|
+| **FastAPI** | ✅ Supported | `[fastapi]` | Includes JinjaX renderer and WebSocket adapter |
+| **Django** | ✅ Supported | `[django]` | Includes Channels, Cotton, and template renderer |
+| **Flask** | 🗓 Planned | — | [Tracking issue #5](https://github.com/fsecada01/component-framework/issues/5) |
+| **Litestar** | 🗓 Planned | — | [Tracking issue #6](https://github.com/fsecada01/component-framework/issues/6) |

+
+## Installation
+
+Install only what you need — `pydantic` is the only mandatory dependency:
+
+```bash
+# Django projects
+pip install "component-framework[django]"
+
+# FastAPI projects
+pip install "component-framework[fastapi]"
+
+# Both adapters
+pip install "component-framework[fastapi,django]"
+
+# Everything
+pip install "component-framework[all]"
+```
+
+### Migrating from 0.2.x
+
+> ⚠️ **Breaking change in 0.3.0**: `fastapi`, `uvicorn`, and `jinjax` are no longer
+> installed by default.
+
+If you were using the FastAPI adapter, add `[fastapi]` to your install command:
+
+```bash
+# Before
+pip install component-framework
+
+# After
+pip install "component-framework[fastapi]"
+```
+
+**CI pipelines** — any workflow step that installs `component-framework` without
+specifying an extras group will stop receiving FastAPI automatically. Update all
+install commands in your GitHub Actions, Dockerfile, tox.ini, Makefile, or other
+CI configuration files.
+
+See [CHANGELOG.md](CHANGELOG.md) for the full list of changes.
