Hi,
I'm pleased to announce ccache version 3.0pre1. I expect this prerelease
(or call it beta release if you want) to be very close to the upcoming
3.0 release functionality-wise, so I encourage everyone to try it out.
And please report any bugs or misbehaviours you find to this mailing
list or the bug tracker.
The source archive can be found here:
http://samba.org/ftp/ccache/ccache-3.0pre1.tar.bz2

To find out what has changed since the previous stable version (2.4),
please see the NEWS file:

Here's a list of changes between 3.0pre0 and 3.0pre1:
Major changes:
- ccache is now GPLv3+ instead of GPLv2+.
- Compression of object files in the cache is now off by default.
Enable by setting CCACHE_COMPRESSION.
- CCACHE_BASEDIR is now off by default since it affects the compiler
semantics too much.
- The way the hash sums are calculated has changed again. Sorry about
that.
New features and improvements:
- Added CCACHE_VERBOSE option.
- Added CCACHE_EXTRAFILES option.
- Improved debug logging.
- The compiler options -imultilib, -iquote, -isysroot, -nostdinc,
-nostdinc++ and -U are no longer hashed in preprocessor mode.
Bug fixes:
- Fixed caching of empty source files in direct mode.
- Avoid storing file hash in manifest in read-only mode.
- Don't compile the preprocessed source code when using -g3 (bug
#7190).
- The compiler option -finput-charset is now handled correctly (bug
#7292).
- umask is now set earlier since ccache_main() may create
files/directories.
- Corrected implementation of strndup() replacement.
- Improved handling of -Wp,* compiler options.
- Various code cleanups.
- The compiler options -Xassembler, -b, -G and -V are now correctly
recognized as taking an argument.
- Computation of the hash sum has been improved to decrease the risk
of collisions.
- Code that uses (or rather: potentially uses) __{DATE,FILE,TIME}__
macros is handled correctly in direct mode.
- Bail out early on the compiler option -arch since it's too hard to
handle.
- Include hostname in temporary file names to avoid potential NFS
race.
- The temporary object file is now renamed (instead of copy+delete) if
possible.
- Improved error checking when reading compressed files from the
cache.
- Improved detection of recursive invocation (bug #7411).
Other:
- Rewrote the manual and other documents into AsciiDoc format.
- Documented that the ".incbin" inline assembler directive causes
problems.
- Improved documentation of how the direct mode works.
- Added "Compiling in different directories" section in the manual.
- Added "Sharing a cache on NFS" section in the manual.
- Improved benchmarking script.
