I'm happy to announce ccache version 3.2.1, which is a bug fix release.

Details may be read in the release notes:

You can run "gpg --verify ccache-3.2.1.tar.*.asc" to check the source
archive integrity after download.

Bug fixes:

- Fixed regression in temporary file handling, which lead to incorrect
  permissions for stats, manifest and ccache.conf files in the cache.

- `CACHEDIR.TAG` files are now created in the [0-9a-f] subdirectories so
that
  ccache.conf is not lost in backups.

- Made the default cache size suffix `G`, as previously documented.

- `-fdiagnostics-color=auto` is now passed to the compiler even if stderr is
  redirected. This fixes a problem when, for instance, a configure test
probes
  if the compiler (wrapped via ccache) supports `-fdiagnostics-color=auto`.

- Added missing documentation for `max_files` and `max_size` configuration
  options.
