+ccache 3.1.notyetreleased
+-------------------------
+Release date: unknown
+
+
+New features and improvements
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+- Added support for `-Xclang` compiler option.
+
+- Improved handling of exit code of internally executed processes.
+
+- Zero length object files in the cache are now rejected as invalid.
+
+- Bail out on option `-gsplit-dwarf` (since it produces multiple output files).
+
+- Compiler option `-fdebug-prefix-map` is now ignored (not part of the hash).
+  (The `-fdebug-prefix-map` option may be used in combination with
+  `CCACHE_BASEDIR` to reuse results across different directories.)
+
+- Added note in documentation that `--ccache-skip` currently does not mean
+  ``don't hash the following option''.
+
+- To enable support for precompiled headers (PCH), `CCACHE_SLOPPINESS` now also
+  needs to include the new `pch_defines` sloppiness. This is because ccache
+  can't detect changes in the source code when only `#define`s have been
+  changed.
+
+- Stale files in the internal temporary directory (`<ccache_dir>/tmp`) are now
+  cleaned up if they are older than one hour.
+
+
+Bug fixes
+~~~~~~~~~
+
+- Fixed path canonicalization in `make_relative_path()` when path doesn't
+  exist.
+
+- Fixed bug in `common_dir_prefix_length()`. This fixes a bug in the
+  `CCACHE_BASEDIR` behavior.
+
+- ccache no longer tries to create the cache directory when `CCACHE_DISABLE` is
+  set.
+
+- Fixed bug when reading manifests with a very large number of file info
+  entries.
+
+- Fixed problem with logging of current working directory.
+
+
