-[Ubuntu releases annually in April](https://wiki.ubuntu.com/Releases). In 2020 the GitHub Actions team [supported the new version by mid June](https://github.com/actions/virtual-environments/issues/228#issuecomment-644065532), so we have an annual reminder for 1st July each year to see if we can upgrade. We can find out [here](https://docs.github.com/en/actions/reference/virtual-environments-for-github-hosted-runners#supported-runners-and-hardware-resources). When we do upgrade to the new version it involves e.g. for 2021, simply replacing every case of `ubuntu-20.04` with `ubuntu-21.04`.
