Support pattern

How GitHub Actions Runner Images has behaved across the cycles tracked here, rather than what its policy documents state. Useful for judging how much runway a version is likely to have before you commit to it.

Support windows are getting shorter: the most recent cycles run about 25 months less than the earlier ones.

Computed from release and end-of-life dates tracked for GitHub Actions Runner Images. Medians are used rather than averages so one unusually short or long release does not skew the figure. Cycles with no recorded end-of-life date are excluded from the support window.
