  ccache news
  ===========
  
 +ccache 3.5
 +----------
 +Release date: unknown
 +
 +Changes
 +~~~~~~~
 +
 +- Renamed `CCACHE_CC` to `CCACHE_COMPILER` (keeping the former as a deprecated
 +  alias).
 +
 +- It is now possible to let ccache hash a precomputed checksum file instead of
 +  the full content of a precompiled header. This can save time for large
 +  precompiled headers. Note that the build system needs to keep the checksum
 +  file in sync with the precompiled header for this to work.
 +
 +- Improved performance substantially when using `hash_dir = false` on platforms
 +  like macOS where `getcwd()` is slow.
 +
 +- Added ``stats updated'' timestamp in `ccache -s` output. This can be useful
 +  if you wonder whether ccache actually was used for your last build.
 +
 +- Renamed ``stats zero time'' to ``stats zeroed'' and documented it. The
 +  counter is also now only present in `ccache -s` output when `ccache -z`
 +  actually has been called.
 +
 +- The content of the `-fsanitize-blacklist` file is now included in the hash,
 +  so updates to the file will now correctly result in separate cache entries.
 +
 +- It's now possible to opt out of building and installing man pages when
 +  running `make install` in the source repository.
 +
 +- If the compiler type can't be detected (e.g. if it is named *cc*), use safer
 +  defaults that won't trip up clang.
 +
 +- Made the ccache test suite work on FreeBSD.
