We are happy to announce the release of coreboot 4.5

The 4.5 release covers commit 80a3df260767 to commit 0bc12abc2b26.

This release is the first since the project switched from doing quarterly releases to doing biannual releases. The next release will be in April of 2017.

Since the last release in April, the coreboot project has had 1889 commits by 119 authors.

The release tarballs and gpg signatures are available in the usual place at https://www.coreboot.org/downloads

There is a 4.5 tag in the git repository, and a branch will be created as needed.
