+:version: 0.12.4
+:milestone-name: 0.12.4
+:milestone: 107
+:prev-version: 0.12.3
+
+* Mill now supports https://mill-build.org/mill/large/selective-execution.html[Selective Execution],
+  allowing you to run tests and other tasks only if they are downstream of a code change.
+  This can be used to greatly speed up pull-request validation and other CI workflows
+  by skipping unrelated tests that cannot possibly be broken by the code change in question
+
+* Mill now generates https://mill-build.org/mill/fundamentals/out-dir.html#_mill_dependency_tree_json[dependency-tree.json]
+  and https://mill-build.org/mill/main-branch/fundamentals/out-dir.html#_mill_invalidation_tree_json[invalidation-tree.json]
+  metadata for every run, which should help make it easier for a user to figure out why a task
+  is being selected and run.
+
+* Support for Bill-Of-Materials/Dependency-Management when downloading third-party JVM dependencies
+  (https://mill-build.org/mill/main-branch/javalib/dependencies.html#_dependency_management[Documentation])
+
+* Built-in support for `mill.bat` launcher to run Mill natively on a Windows environment
+  https://github.com/com-lihaoyi/mill/pull/4052[#4052]
+
+* Added documentation for https://mill-build.org/mill/migrating/migrating.html[Migrating to Mill],
+  to try and help people who may be trying to move their existing codebase onto Mill from other build tools
+
+* Significant speedups for task resolution logic https://github.com/com-lihaoyi/mill/pull/4132[#4132],
+  which should speed up cached-build workflows in particular
+
+* Improve precise of code signature task invalidation, reducing the amount of spurious
+  task invalidations in the presence of multi-file builds https://github.com/com-lihaoyi/mill/pull/4113[#4113]
+  https://github.com/com-lihaoyi/mill/pull/4116[#4116]
+
+* Reduced overhead of terminal prompt UI https://github.com/com-lihaoyi/mill/pull/4095[#4095]
+  https://github.com/com-lihaoyi/mill/pull/4110[#4110]
