The Git project makes no formal guarantee for any +older maintenance tracks to receive updates. In practice, +though, critical vulnerability fixes are applied not only to the +most recent track, but to at least a couple more maintenance +tracks. + +This is typically done by making the fix on the oldest and still +relevant maintenance track, and merging it upwards to newer and +newer maintenance tracks. + +For example, v2.24.1 was released to address a couple of +[CVEs](https://cve.mitre.org/), and at the same time v2.14.6, +v2.15.4, v2.16.6, v2.17.3, v2.18.2, v2.19.3, v2.20.2, v2.21.1, +v2.22.2 and v2.23.1 were released. |
