  ccache news
  ===========
  
 +ccache 3.6
 +----------
 +Unreleased
 +
 +Changes
 +~~~~~~~
 +
 +- Added support for GCC's `-ffile-prefix-map` option. The `-fmacro-prefix-map`
 +  option is now also skipped from the hash.
 +
 +- Added support for multiple `-fsanitize-blacklist` arguments, thus preventing
 +  ccache from
 +
 +- Fixed a problem due to Clang overwriting the output file when compiling an
 +  assembler file.
 +
 +- Clarified the manual to explain the reasoning behind the “file_macro”
 +  sloppiness setting in a better way.
 +
 +- ccache now handles several levels of nonexistent directories when rewriting
 +  absolute paths to relative.
 +
 +- A new ``sloppiness'' setting *clang_index_store* makes ccache skip the Clang
 +  compiler option *-index-store-path* and its argument when computing the
 +  manifest hash. This is useful if you use Xcode, which uses an index store
 +  path derived from the local project path. Note that the index store won't be
 +  updated correctly on cache hits if you enable this option.
 +
