Upgrading glean_parser
To upgrade the version of glean_parser used by the Glean SDK, run the bin/update-glean-parser-version.sh script, providing the version as a command line parameter:
bin/update-glean-parser-version.sh 1.28.3
This will update the version in all of the required places. Commit those changes to git and submit a pull request.
No further steps are required to use the new version of glean_parser for code generation: all of the build integrations automatically update glean_parser to the correct version.
For testing the Glean Python bindings, the virtual environment needs to be deleted to force an upgrade of glean_parser:
rm -rf glean-core/python/.venv*
