    to true. See bazelbuild#16654 for
    details.
  - `cquery --output=files` also outputs source files.

    Closes bazelbuild#16602.
  - `--incompatible_strict_conflict_checks` is flipped to true. See
    bazelbuild#16729 for details.
  - This changes the behavior of Python version in exec/host
    configuration. Mitigation is to set Python version on the targets.
  - `--features` only applies to targets built in the target
    configuration, and `--host_features` is used for the host / exec
    configuration (gated behind `--incompatible_use_host_features`)

    Fixes bazelbuild#13839

    Closes bazelbuild#16626.

New features:

  - The aquery and cquery commands now respect the --query_file flag
    just like the query command.

Important changes:

  - The new path variable `$(rlocationpath ...)` and its plural form
    `$(rlocationpaths ...)` can be used to expand labels to the paths
    accepted by the `Rlocation` function of runfiles libraries. This
    is the preferred way to access data dependencies at runtime and
    works on all platforms, even when runfiles are not enabled (e.g.,
    on Windows by default).

    Work towards bazelbuild#16124
    Fixes bazelbuild#10923

    Closes bazelbuild#16428.
  - Starlark `print()` statements are now emitted iff the line of
    code is executed. They are no longer replayed on subsequent
    invocations unless the Starlark code is re-executed.
    Additionally, multiple identical `print()` statements (same
    string from the same line of code, e.g. from a loop) are all
    emitted and no longer deduplicated.
  - Fixes a bug where some compilation flags would not be applied to
    a cc_test
  - Added a `native.package_relative_label()` function, which
    converts a label string to a Label object in the context of the
    calling package, in contrast to `Label()`, which does so in the
    context of the current .bzl file. Both functions now also accept
    relative labels such as `:foo`, and are idempotent.
  - Adds coverage metric support to android_local_test
  - Fixed an issue where WORKSPACE and WORKSPACE-loaded .bzl files
    couldn't see the Bzlmod root module's mappings when Bzlmod is
    enabled.
  - Added `native.module_name()` and `native.module_version()` to
    allow BUILD macro authors to acquire information about which
    Bazel module the current repo is associated with.
  - `@foo` labels can now be used on the command line as the
    top-level target (that is, `bazel build @foo` now works).
    Double-dot syntax is now forbidden (`bazel build ../foo` will no
    longer work).
  - Added preliminary support for a lockfile for Bzlmod. It's
    disabled by default; use `--lockfile_mode=update` to enable it.
    This lockfile contains only Bazel module information; it does not
    involve module extensions.
  - Added a new `max_compatibility_level` attribute to the
    `bazel_dep` directive, which allows version selection to upgrade
    a dependency up to the specified compatibility level.

  - `--experimental_remote_grpc_log` has been renamed to
    `--remote_grpc_log`

    Closes bazelbuild#18180.
