+### [5.0.1-alpha.0](https://github.com/plone/mockup/compare/5.0.0-alpha.0...5.0.1-alpha.0) (2022-05-17)
+
+
+### Features
+
+
+* **Build:** Use dynamic module federation. ([6aefc4b](https://github.com/plone/mockup/commit/6aefc4bd108b37aa2c292f6243e60a1005c8517f))
+
+
+
+### Bug Fixes
+
+
+* **relateditems:** Move Select2 out of init. ([0a7c631](https://github.com/plone/mockup/commit/0a7c631d30553a43a43d616f3947ac0bc6232113))
+If it wasn't already registered, it would register and scan the document now.
+If there were previous relateditems already modifying the DOM structure
+and placing pat-select2 classes to some items, the import here would try
+to initialize them.
+But those pat-select2 items were meant to be initialized via the
+Patternslib API and not automatically and are missing some configuration
+needed by select2 (query attribute...).
+By moving the Select2 out of the init and importing it early fixes this
+problem.
+
+Note: This happened in plone.app.mosaic with module federation.
+pat-select2 was already directly imported by the main Mockup bundle.
+But since we didn't have a global pattern registry, the pattern was
+re-initialized where it wouldn't have to.
+Since the change in Patternslib 8.0.0 with a global pattern registry
+this fix might become obsolete.
+
+However, we should have an eye on dynamic pattern imports immediately
+registering and scanning the docment and possibly prevent that in some
+way.
+
+See: https://github.com/Patternslib/Patterns/issues/961
+
+
+### Maintenance
+
+
+* **Build:** Add build:webpack:dev:plone as package.json script to allow for a Plone development build. ([acf9839](https://github.com/plone/mockup/commit/acf9839ddf5b29c34068085ce3ac8a4d8a90f0c7))
+
+
+* **Build:** Add prerelease target in Makefile. ([ea8d4e4](https://github.com/plone/mockup/commit/ea8d4e4fc2f87f1757ffd984be00926080f8795b))
+
+
+* **Build:** Upgrade dependencies. ([2312ee5](https://github.com/plone/mockup/commit/2312ee55eb90340bc8fb35db102f7befd71b81d4))
+
+
+* **Cleanup:** Cleanup unused parameter in webpack config. ([f749505](https://github.com/plone/mockup/commit/f7495052f02f9fcbed0e56308359d9ad64b7a679))
+
+
+* **Cleanup:** Remove pat-content-browser. ([abd58f7](https://github.com/plone/mockup/commit/abd58f77e0a8cc7ff5807ce6ea322a38fa7c5b28))
+This can be provided by an external bundle.
+
+* **Makefile:** Add watch-plone and bundle-plone targets to Makefile. ([62332d1](https://github.com/plone/mockup/commit/62332d1914de6ea57829f2cf4e5f908cd7f69d98))
+
+
+* **pat querystring:** Cleanup - direct import of Select2 is not necessary. ([13d0e0d](https://github.com/plone/mockup/commit/13d0e0d9535c958eaf662308477b985d1a6c9225))
