Release 10.0.0-pre.20260801.1 (2026-08-10)

Baseline: 14498c82d1af1ee127ac2140f0bfdf0f62d36c60

Cherry picks:

   + 909985a3b9a1f71106e7cba31eb862078e5bdebe:
     Automated rollback of commit
     2558ffede4c29cc41c7080eadd3118cb12509517.

Incompatible changes:

  - The Windows shell launcher now again prepends rather than appends
    the directory containing the shell binary, restoring the behavior
    of Bazel 8.x. This is technically an incompatible change, but
    deemed necessary due to the unexpected and widespread
    implications of the change in 9.0.0. See
    https://github.com/bazelbuild/bazel/issues/29637 for more context.

New features:

  - The `BAZEL_LLVM_PROFILE_FILE` environment variable can now
    be used to customize the LLVM profile filename pattern for C++
    coverage
    collection (e.g. `--test_env=BAZEL_LLVM_PROFILE_FILE=%p.profraw`).
    Defaults to `%h-%p-%m.profraw` when unset.

Important changes:

  - --experimental_split_coverage_processing and
    --experimental_fetch_all_coverage_outputs default to true.
  - Retry 408 and 429 status codes with HTTP remote caching.
  - Fixed a bug that could cause `ignore_directories()` to not ignore
    directories.

+
+```
+Baseline: b66e78bad319b5107a5d1be67343a5705360e87a
+```
+
+New features:
+
+  - Added `--experimental_remote_cache_chunking_function` to select
+    the content-defined chunking function used by
+    `--experimental_remote_cache_chunking`. Supported values are
+    `auto` (the default, which negotiates the function from the
+    server capabilities, preferring FastCDC 2020), `fast_cdc_2020`
+    and `rep_max_cdc`.
+
+Important changes:
+
+  - Fixed `repository_ctx.download_and_extract` failing with an
+    "Expected a file with a ... suffix" error when
+    `--downloader_config` blocks all URLs and the archive is served
+    from the repository cache.
+  - `--incompatible_modify_execution_info_additive` is now deprecated
+    and a no-op. When `--modify_execution_info` is specified multiple
+    times, all values are always applied in order.
