+## [CMake 3.24][CMake master]: WIP

+The next release is shaping up to be a fantastic release. Package writers are
+getting integration between `find_package` and `FetchContent` that will allow
+"download if missing" workflows, and is configurable by packagers. Similarly,
+warnings as errors can be set by a package and removed by packagers, as well
+(still make sure not to do this unless you are being build as the main
+project!).
+
+
+* `--fresh` option removes the old cache when running.
+* `find_package` and `FetchContent` now have integration - you have options to download missing dependencies.
+* `find_package` has a new `GLOBAL` option.
+* `CMAKE_PROJECT_TOP_LEVEL_INCLUDES` allows a user (like packagers) to inject pre-project code.
+* `PATH` management for generator expressions.
+* `CMAKE_COLOR_DIAGNOSTICS` env var & variable added, replacing `CMAKE_COLOR_MAKEFILE`.
+* You can disable `find_*` searching the install prefix.
+* `COMPILE_WARNING_AS_ERROR` property and `CMAKE_` variable, and `--compile-no-warning-as-error` to disable it.
+* CUDA supports `native` to compile for the current GPUs detected.
+* `SYSTEM` includes now are respected on MSVC generators.
+* Better support for MSVC, XCode, and others.
+* `LLVMFlang` compiler support.
