Changes
- No major feature changes -- this is primarily a maintenance release.
- Experimental: the command line flags
-experimental_read_build_files_dirand-experimental_write_build_files_dirmay be used to read and write build files from alternate directories, which may be outside the repository root. If a file is read from a different directory, build files in the source tree are ignored. If a file is written to an alternate directory, build files in the source tree are not modified. These flags may change in the future.
