ccache 3.2.1
------------
Release date: 2014-12-10
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.
