+```
+
+Incompatible changes:
+
+ - Bazel releases that include a bundled JDK now use the system
+ trust store for certificates by default. Set
+ `-Djavax.net.ssl.trustStore` and `-Djavax.net.ssl.trustStoreType`
+ via `--host_jvm_args` to override the default location.
+
+New features:
+
+ - The `--experimental_cancel_concurrent_tests` option now accepts
+ the values `on_passed`, `on_failed` and `never` and cancels
+ concurrent test runs on the first matching result. If enabled,
+ it's now effective by default and no longer requires
+ `--test_strategy=standalone` to be passed explicitly.

+ 8aecefa932e8064daa performance regression.
+```
+
+Important changes:
+
+ - Tool paths specified in `cc_toolchain` action configs are now
+ normalized based on the current execution platform's OS rather
+ than the host OS. In particular, Windows-style absolute paths are
+ now treated as absolute paths when building on a Windows executor
+ from a non-Windows host.

+```
+
+New features:
+
+ - The new `--*_env==NAME` syntax can be used with any of
+ `--action_env`, `--host_action_env`, `--repo_env`, `--run_env`,
+ and `--test_env` to undo any previous occurrences of the
+ respective flags for that environment variable name. For
+ `--repo_env` and `--run_env`, this also results in the variable
+ being unset if it is set in the environment of the Bazel client.

+## Release 9.0.0-pre.20250716.1 (2025-07-23)
+
+```
+Baseline: 3e62cbbd9410e2a52d551cc7c00b9e2984d7ec02
+```
+
+Important changes:
+
+ - `ctx.actions.write` now supports path mapping when passed an
+ `Args` object. Use the `mnemonics` attribute to assign it a
+ dedicated mnemonic, which can then be used with
+ `--modify_execution_info` to opt in to path mapping (see
+ https://github.com/bazelbuild/bazel/discussions/22658 for details
+ on path mapping).

+
+## Release 9.0.0-pre.20250714.1 (2025-07-18)
+
+```
+Baseline: e08faa5de8095fe27223b6af84b41fd135aa9b4a
+```
+
+Incompatible changes:
+
+ - `linking_context.linkstamps` has been removed.
+
+Important changes:
+
+ - If a cc toolchain feature named `shorten_virtual_includes` is
+ enabled, virtual include header files are linked under
+ `bin/_virtual_includes/<hash of target path>` instead of
+ `bin/<target package path>/_virtual_includes/<target name>`. This
+ shortens the virtual include paths which is critical for
+ mitigating long path issue with MSVC on Windows.

+## Release 9.0.0-pre.20250710.1 (2025-07-16)
+
+```
+Baseline: ed358a15be98fe048494fa2e834ebad66b393515
+```
+
+New features:
+
+ - The mnemonic of a file write action can now be set via the
+ `mnemonic` parameter of `ctx.actions.write`.
+
+Important changes:
+
+ - Symbolic macros which use inherit_attrs now correctly inherit the
+ aspect_hints attribute.

+Baseline: 07bd9661b56710aac7670738e81338715946785e
+```
+
+Important changes:
+
+ - Branches will always be merged as best as possible based on
+ branch and
+ block numbers during coverage report generation.
+ - `--experimental_worker_for_repo_fetching` is removed.
+ - Modules backed by `http_archive` or `git_repository` no longer
+ require a MODULE.bazel file to be contained in the source archive.

+Baseline: c3198249288246211a2e7d5e9f28c4837a37f3b0
+```
+
+Important changes:
+
+ - Added `--incompatible_compact_repo_mapping_manifest`, which
+ causes the repo mapping manifest file for runfiles to use a more
+ compat format when necessary.

+ - `--combined_report` now defaults to `lcov` (was: `none`).
+
+New features:
+
+ - `repository_ctx.download_and_extract` now supports the `.whl`
+ file extension for Python wheel files, treating them as ZIP
+ archives under PEP 427.
+
+Important changes:
+
+ - Rules can now register their own baseline coverage files in LCOV
+ format via the new `baseline_coverage_files` parameter of
+ `ctx.instrumented_files_info`. If the target matches the
+ instrumentation filter, Bazel will merge the data into the
+ combined coverage report generated with `--combined_report`.

+
+Important changes:
+
+ - Added the `load_wasm` and `execute_wasm` methods to
+ `repository_ctx` and `module_ctx` that allow repo rules and

+ only available if `--experimental_repository_ctx_execute_wasm` is
