coreboot 4.2 release notes
|
||
==========================
|
||
|
||
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
