+## Release v2.19.0a0 (2024-09-05)
+
+
+### Breaking Changes
+
+- `pre_install` and `post_install` signals now receive the list of packages to be installed, instead of a candidate mapping. ([#3144](https://github.com/pdm-project/pdm/issues/3144))
+
+### Features & Improvements
+
+- Deprecate `Core.synchronizer_class` attribute. To get the synchronizer class, use `Project.get_synchronizer` method instead.
+  Deprecate `Core.resolver_class` attribute. To get the resolver class, use `Project.get_resolver` method instead. ([#3144](https://github.com/pdm-project/pdm/issues/3144))
+- Add experimental support for `uv` as the resolver and installer. One can opt in by setting `use_uv` to `true` using `pdm config` command. ([#3144](https://github.com/pdm-project/pdm/issues/3144))
+
+### Bug Fixes
+
+- Respect the `excludes` and `overrides` settings when installing packages. ([#3113](https://github.com/pdm-project/pdm/issues/3113))
+- Fix a bug of export command that packages with extras are included twice. ([#3123](https://github.com/pdm-project/pdm/issues/3123))
+- Remove empty groups when removing packages with `pdm remove`. ([#3133](https://github.com/pdm-project/pdm/issues/3133))
+- When running `pdm venv purge`, if the current project's python version had been referencing the removed venv then clear it out. ([#3137](https://github.com/pdm-project/pdm/issues/3137))
