Bazel 4.0 is a major release and Bazel’s first LTS release. It contains new features and backwards incompatible changes.
After significant investment in understanding how best to build the Android Platform correctly and quickly, we are pleased to announce that the Android Platform is migrating from its current build systems (Soong and Make) to Bazel. While components of Bazel have been already checked into the Android Open Source Project (AOSP) source tree, this will be a phased migration over the next few Android releases which includes many concrete and digestible milestones to make the transformation as seamless and easy as possible. There will be no immediate impact to the Android Platform build workflow or the existing supported Android Platform Build tools in 2020 or 2021. Some of the changes to support Android Platform builds are already in Bazel, such as Bazel’s ability to parse and execute Ninja files to support a gradual migration.
You asked, we answered -- JSON support for persistent workers is here!
With only 24 hours to go, BazelCon 2020 is shaping up to be a much anticipated gathering for the Bazel community and broader Build ecosystem. With over 1000 attendees, presentations by Googlers, as well as talks from industry Build leaders from Twitter, Dropbox, Uber, Pinterest, GrabTaxi, and more, we hope BazelCon 2020 will provide an opportunity for knowledge sharing, networking, and community building.
tl;dr Bazel will now provide Long Term Support (LTS) Releases as well as regular rolling releases.
