For the GitHub release itself, I was planning to make these the release notes:

	Apache Grails (incubating) 7.0.0-M4 is the first release for Grails under the Apache Software Foundation (ASF).  This release focuses first on meeting the requirements of the ASF & improving the developer experience of Grails itself & Grails Applications.  As part of this transition, the developers moved to a mono repository, reworked the way the various Grails CLIs work, modernized its build system, modernized the various Grails Gradle Tasks, modernized the various Grails Gradle Plugins, worked towards reproducible builds, added license headers to our source code, and changed the maven coordinates of all Grails Artifacts.  

	Here is the detailed list since 7.0.0-M3:
	* PR #14750 - support non-persistent super classes for @Autotimestamp
	* Issue #14745 - remove deprecated doc method on Grails Plugins
	* Issue #14745 - remove duplicate grails.factories & grails-plugin.xml files now that AST generation is working correctly

	* Issue #14706 - rework both grailsw & grails-shell-cli to be testable outside of releases
	* Issue #14679 - generate reproducible groovydoc jars
	* Issue #14679 - fix profile compilation to generate reproducible jars

	* PR #14709 - switch to Gradle 8.14
	* PR #14678 - add support for external config locations
	* Refactor grails into a mono repo (grails-views, gsp, data mapping, geb, etc are all merged into core now)
	* As part of the mono repo transition, several Deprecated classes were removed from the views project; see the upgrade guide for the details.
	* Issue #14679 - refactor grails build to be parallel & lazy
	* Issue #14679 - change all Grails gradle tasks to support Caching where appropriate and support lazy style configuration
	* Issue #14679 - Redesign the Grails Data TCK to support modern versions of Java
	* Issue #14679 - Support consistent property dates in generated property files when SOURCE_DATE_EPOCH is set
	* Issue #14679 - Make grails.factories generation reproducible
	* Issue #14679 - Refactor Grails AST Transformations to take advantage of Groovy's TransformWithPriority and enforce transforms always run in the order defined by the class `GroovyTransformOrder`
	* Issue #14679 - Remove manifest attributes that could vary on the Grails jars (Built-By, Created-By etc)
	* Issue #14679 - Fix sourcejar creation to not contain duplicates
	* Issue #14679 - Fix javadoc jars to be generated based on groovydoc & to not contain duplicates
	* Issue #14679 - Change AST transforms to be reproducible by adopting determined ordering collections

	* Issue #13850 - introduce `grails-common` to share common code between Grails Data Mapping & Grails-Core
	* Issue #14679 - add scripts to confirm reproducibility of Grails; currently 14 of 290 jars are reproducible
	* Issue #14679 - make TagLib lookups reproducible
	* PR# 14671 - switch to webjars for test css/js assets instead of checked in files
	* The Grails Gradle plugin had a bug that caused plugin resolution issues that was fixed after the last milestone.
	* Rework the grails bom to generate valid Gradle modules, be easier to maintain, and valid pom files.  Enhance the documentation process to parse the bom & generate the published versions in the grails doc.


	And in addition to all of this: 
	* We changed all coordinates of Grails to be org.apache.grails based. See https://github.com/apache/grails-core/blob/7.0.x/RENAME.md for how we mapped these libraries.  There is also a script documented in the upgrade guide to assist in upgrading.
	* Significant test fixes
	* Significant documentation updates & changes
	* Addition of license headers to Grails Source
	* Addition of NOTICE to Grails Source
	* Created https://repo.grails.org/grails/restricted/ to replace https://repo.grails.org/grails/core longer term.  This virtual repo's scope is significantly reduced to help reduce the chance of using outdated libraries.

	Upgrade instructions are available in the documentation.
