1 coreboot 4.2 release notes
2 ==========================
4 Halloween 2015 release - just as scary as that sounds
6 Dear coreboot community,
7 today marks the release of coreboot 4.2, the second release on our time
8 based release schedule. Since 4.1 there were 936 commits by 90 authors,
9 increasing the code base by approximately 17000 lines of code. We saw 35
10 new contributors - welcome to coreboot! More than 34 developers were
11 active as reviewers in that period. Thanks go to all contributors who
12 helped shape this release.
14 As with 4.1, the release tarballs are available at
15 http://www.coreboot.org/releases/. There's also a 4.2 tag and branch in
18 This marks the first release that features a changelog comparing it to
19 the previous release. There was some limited testing to make sure that
20 the code is usable, and it boots on some devices. A structured test plan
21 will only become part of the release procedure of future versions. I'm
22 grateful to Martin for assembling this release's changelog.
24 This is also the first release that will be followed by the removal of
25 old, unused code. There will be a policy on how to announce deprecation
26 and removal of mainboard and chipset code for future releases.
