Angular 20 stops getting security fixes on 28 November 2026, according to Angular's release page, where version 20's long-term support is listed as ending that day.

What is still supported

After 28 November, a fix for a security issue ships for versions 21 and 22 only. Version 21 is covered until June 2027 and version 22 until June 2028.

What to do this sprint

Run ng version to see where each app stands. ng update moves one major version at a time, so going from 20 to 22 means two steps. Plan them now rather than in the week support ends.

I post short notes like this on LinkedIn.

Cream card: "Angular 20 support ends in two weeks." Still on 20? Plan the upgrade for this sprint.
