The changes were, for the most part, all over +the place, touching every part of the repository: chipsets, mainboards, +tools, build system, documentation. +In that time we also had 70 authors made their first commit to coreboot: +Welcome and to many more! +Finally, a big Thank You to all contributors who helped shape the +coreboot project, community and code with their effort, no matter if +through development, review, testing, documentation or by helping people +asking questions on our venues like IRC or our mailing list. + +Clean up +-------- +If there's any topic to give to this release, "clean up" might be the +most appropriate: There was lots of effort to bring the codebase into +compliance with our coding style, to remove old idioms that we'd like +to retire like the overloaded `device_t` data type, and to let features +percolate through the entire tree to bring more uniformity to its parts. + +For example, during the coreboot 4.4 cycle, coreboot gained the notion +of mainboard variants to avoid duplication of code in rather similar +mainboards. + +Back then, this feature was developed and used mostly for the benefit +of Chrome OS devices, but more recently the code for various Lenovo +Thinkpads was deduplicated in the same way. + +Another part of cleaning up our tree is improving our tools that help +developers follow coding style and avoid mistakes, as well as the +infrastructure we have for automated build tests and we've seen quite +some activity in that space as well. + +Documentation +------------- +Since the last release we also moved the documentation into the +repository. No need for a special wiki account to edit the documentation, +and by colocating sources and documentation, it's easier to keep the +latter in sync with the code, too. + +This effort is still under way, which is why we still host the old wiki (now +read-only) in parallel to the [new documentation +site](https://doc.coreboot.org) that is rendered from coreboot.git's +Documentation/ directory. + +Blobs handling +-------------- +Another big change is in our blobs handling: Given that Intel now +provides a reasonably licensed repository with FSP binaries, we were +able to mirror it to coreboot.org and integrate it in the build system. +This makes it easier to have working images out of the box for devices +that depend on Intel's proprietary init code. + +As usual the blobs aren't part of the coreboot tree and only downloaded +with the `USE_BLOBS` options. + +Deprecations +------------ +One of the first changes to coreboot after the 4.8 release was to remove +boards that didn't support certain new features and were apparently +unmaintained, as discussed in the release notes of coreboot 4.6. + +We didn't follow up on all plans made back then to deprecate boards more +aggressively: The board status reporting mechanism is still rather raw +and therefore places quite a burden on otherwise sympathetic contributors +of build results. + +Also, there will be no deprecations after 4.10: Due to its slipping +schedule, coreboot 4.9 is released rather late, and as a result 4.10 +will only see about 4 months of development. We considered that a rather +short timeframe in which to bring old boards up to new standards, and +so the next deprecation cycle may be announced with 4.10 to occur after +4.11 is released, in late 2019.
