Release 8.1.0 (2025-02-13)
Bazel 8.1.0 is a minor LTS release. It is fully backward compatible with Bazel 8.0 and contains selected changes by the Bazel community and Google engineers.
General
- On Linux, the default limit on the number of --watchfs file events per directory has been raised to 10,000 (from 500). If needed, it can be increased further via --host_jvm_args=-Djdk.nio.file.WatchService.maxEventsPerPoll=<limit>. (#24872)
C++ / Objective-C
- Added conlyopts and cxxopts to objc_library. (#25022)
Configurability
- Changing any part of --run_under that isn't the label (such as the shell command) no longer invalidates the analysis cache. (#25023)
- The new no_match_error attribute on toolchain_type can be used to show a custom message when no matching toolchain is found for that type, but one is required. (#25178)
External Dependencies
- --experimental_downloader_config now supports the ~ character for the home directory. (#24978)
- Added repository_ctx.original_name, which contains the original value of the name attribute as specified at the repo rule call site. (#25191)
Remote Execution
- CAS requests made when Bazel downloads a blob with Build without the Bytes enabled now provide metadata with an action ID of input if the blob is downloaded as the input to a local action and output if it is a requested action output. (#25058)
Starlark / Build Language
- Add a set data type to Starlark. (#25111)
