ccache news
===========
+ccache 3.7.10
+------------
+Release date: 2020-06-22
+
+Bug fixes
+~~~~~~~~~
+
+- Improved handling of profiling options. ccache should now work correctly for
+ profiling options like `-fprofile-{generate,use}[=path]` for GCC ≥ 9 and
+ Clang as well as `-fauto-profile[=path]` and the Clang-specific
+ `-fprofile-instr-{generate,use}[=path]` and `-fprofile-sample-{use,accurate}`
+ options.
+
+- ccache now copies files directly from the cache to the destination file
+ instead of via a temporary file. This avoids problems when using filenames
+ long enough to be near the file system's filename max limit.
+
+- When the hard-link mode is enabled, ccache now only uses hard links for
+ object files, not other files like dependency files. This is because
+ compilers unlink object files before writing to them but they don't do that
+ for dependency files, so the latter can become overwritten and therefore
+ corrupted in the cache.
+
+- Fixed a glitch related to hard-link mode and an empty cache.
+
+- ccache now supports the ccache.conf file to be a symlink.
+
+- Temporary files are now deleted immediately on signals like SIGTERM and
+ SIGINT instead of some time later in a cleanup phase.
+
+- Fixed a bug that affected ccache's `-o/--set-config` option for the
+ `base_dir` and `cache_dir_levels` keys.
+
