| # TeamCity should use a newly created branches that matches the pattern `UTC-<YYYY-MM-DD>` and is the only branch matching that pattern. We rename past nightly test branches to avoid there being more than one `UTC-<YYYY-MM-DD>` branch (i.e. only one branch that matches the filter (+:UTC-*,-:UTC-nightly-tests*)). This workflow also removes renamed branches once they get past a certain age. | |
