Nice job all. Patrick, I'm looking forward t the next release detailing how many files and lines were removed :-)
include, oh sad, the 440lx :-)

(Halloween 2015 release - just as scary as that sounds)
Dear coreboot community,
today marks the release of coreboot 4.2, the second release on our time based release schedule. Since 4.1 there were 936 commits by 90 authors, increasing the code base by approximately 17000 lines of code. We saw 35 new contributors
- welcome to coreboot! More than 34 developers were active as
reviewers in that period. Thanks go to all contributors who helped shape this release.
As with 4.1, the release tarballs are available at http://www.coreboot.org/releases/. There's also a 4.2 tag and branch in the git repository.
This marks the first release that features a changelog comparing it to the previous release. There was some limited testing to make sure that the code is usable, and it boots on some devices. A structured test plan will only become part of the release procedure of future versions. I'm grateful to Martin for assembling this release's changelog.
This is also the first release that will be followed by the removal of old, unused code. There will be a policy on how to announce deprecation and removal of mainboard and chipset code for future releases.
Regards, Patrick

Build system:
- Store a minimized coreboot config file in cbfs instead of the full config
- Store the payload config and revision in CBFS when that info is available
- Add -compression option for cbfs-files-y. Valid entries are now -file,
-type, -align, and -compression
- Change Microcode inclusion method from building .h files to pre-built
binaries
- Update Builder tests for each commit to test utilities and run lint tools
- Many other small makefile and build changes and fixes
- Remove expert mode as a Kconfig option
Utilities:
- Many fixes and updates to many utilities (158 total commits)
- ifdtool: Update for skylake, handle region masks correctly
- crossgcc: Update to gcc 5.2.0

adding them
- Decompress stage files on extraction and turn them into ELF binaries
- Header sizes are now variable, containing extended attributes
- Add compression tags to all cbfs headers so all cbfs files can be
compressed
- Add and align CBFS components in one pass instead of two
