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`. (#​21960)
