Details may be read in the release notes:

You can run "gpg --verify ccache-3.2.2.tar.*.asc" to check the source

integrity after download.

New features and improvements:

- Added support for "CCACHE_COMPILERCHECK=string:<value>". This is a faster
  alternative to "CCACHE_COMPILERCHECK=<command>" if the command's output
can
  be precalculated by the build system.

- Add support for caching code coverage results (compiling for gcov).

Bug fixes:

- Fixed bug which could result in false cache hits when source code contains
  '"' followed by " /*" or " //" (with variations).

- Made hash of cached result created with and without "CCACHE_CPP2"
different.
  This makes it possible to rebuild with "CCACHE_CPP2" set without having to
  clear the cache to get new results.

- Don't try to reset a non-existing stats file. This avoids "No such file or
  directory" messages in the ccache log when the cache directory doesn't
exist.

- Fixed a bug where ccache deleted clang diagnostics after compiler
failures.

- Avoid performing an unnecessary copy of the object file on a cache miss.

- Bail out on too hard compiler option "-fmodules".

- Bail out on too hard compiler option "-fplugin=libcc1plugin" (interaction
  with GDB).

- Fixed build error when compiling ccache with recent clang versions.

- Removed signal-unsafe code from signal handler.

- Corrected logic for when to output cached stderr.

- Wipe the whole cached result on failure retrieving a cached file.

- Fixed build error when compiling ccache with recent clang versions.
