Release Notes: Configurability: + aquery: `//foo:bar` now means "all configured targets with label `//foo:bar`" instead of "choose an arbitrary configured target with label `//foo:bar`". This is in line with cquery behavior. (#22135) + Added a new flag `--incompatible_disable_native_repo_rules` to disable native repo rule usage in WORKSPACE. All native repo rules now have a Starlark counterpart that can be used in both WORKSPACE and Bzlmod; see #22080 for more details. (#22203) + Starlark command-line flags can now be referred to through `alias` targets. (#22212) ExternalDeps: + bzlmod `git_repository` now accepts the `strip_prefix` arg and passes it to the underlying `git_repository` call. (#22137) + Added a new `include()` directive to `MODULE.bazel` files, which allows the root module file to be divided into multiple segments. (#22204) + Fixed certain deadlocks in repo fetching with worker threads (`--experimental_worker_for_repo_fetching=auto`). (#22261) + `print` statements in module files are now only executed for the root module and modules subject to non-registry overrides (e.g. `local_path_override`). (#22263) + The new `refresh` value for `--lockfile_mode` behaves like the `update` mode, but additionally forces a refresh of mutable registry content (yanked versions and missing module versions) when switched to or from time to time while enabled. (#22371) + `Label` instances passed to `print` or `fail` as positional arguments are now formatted with apparent repository names (optimized for human readability). (#22460) + Changes to environment variables read via `getenv` now correctly invalidate module extensions. (#22541) + Git merge conflicts in `MODULE.bazel.lock` files can be resolved automatically. See https://bazel.build/external/lockfile#automatic-resolution for the required setup. (#22650) OSS: + Bazel on Linux and BSD now respects the XDG_CACHE_HOME environment variable instead of assuming that ~/.cache/bazel is writable. (#21817) Performance: + Paths in the Linux sandbox are now again identical to those outside the sandbox, even with `--incompatible_sandbox_hermetic_tmp`. (#22407) Remote-Exec: + The combined coverage report produced via `--combined_report=lcov` is now announced on the BES via the new `CoverageReport` event. (#22327) + The compact and full execution logs now contain start times for spawns (if available). (#22341) Rules-CPP: + The default Unix C++ toolchain now supports the `parse_headers` feature to validate header files with `--process_headers_in_dependencies`. (#22369) Starlark-Interpreter: + Starlark `min` and `max` buitins now allow a `key` callback, similarly to `sorted`.
