  "message": "{r,m}ctx.download*: report size of downloaded file (https://github.com/bazelbuild/bazel/pull/29463)\n\n### Description\n\nAdds a new structure field `size_bytes` in the return value of `rctx.download` (and friends) containing the file size of the downloaded file.\n\n### Motivation\n\nThis is a useful piece of metadata Bazel provides to repository rules and module extensions. Motivation for adding this: I need the ability to annotate BUILD files with sizes of downloaded files in rules_runfiles_group (https://github.com/hermeticbuild/rules_runfiles_group). This makes it possible to merge runfiles groups based on their \"weight\", which may include actual file sizes of *_import targets (java_import, cc_import, ...).\n\n### Build API Changes\n\nIt does affect the Build API, but is backwards compatible (adding a new field).\nExisting users will not be impacted.\n\n### Checklist\n\n- [x] I have added tests for the new use cases (if any).\n- [x] I have updated the documentation (if applicable).\n\n### Release Notes\n\nRELNOTES[NEW]: {r,m}ctx.download* report the size of downloaded files\nRELNOTES: Addition to the user-facing Build API\n\nCloses #29463.\n\nPiperOrigin-RevId: 910706646\nChange-Id: I980cdee803810e1fb6222f69782fcad2648af68d\n",
