We're pleased to announce the release of Bazel 9.0! This LTS release is the culmination of some multi-year efforts to lay the groundwork for a healthier Bazel ecosystem, and we're excited to see these efforts finally land. Read the full release notes for Bazel 9.0.
On 2025-12-26, at 07:35 UTC, the SSL certificates for many *.bazel.build domains expired. This resulted in widespread build breakages for many Bazel users, as several crucial domains serve essential functionality used by nearly all Bazel builds. It was reported by users on GitHub, Slack, and the bazel-discuss mailing list. The outage lasted for approximately 13 hours before being resolved.
Autumn is BazelCon season, and this year was no different: Last month we hosted BazelCon 2025 together with the Linux Foundation and our sponsors.
