Version branches

If you plan to work on a specific issue within Jetty, make sure to target the correct branch for your pull request.

Table 1. Active Jetty branches
jetty-12.0.x	Development (default branch)	Servlet 6.0	Java 17+
jetty-11.0.x	Maintenance	Servlet 5.0	Java 11+
jetty-10.0.x	Maintenance	Servlet 4.0	Java 11+
jetty-9.4.x	End of Community Support	Servlet 3.1	Java 8+

Maintenance branches are periodically merged into active development branches.

Older branches are only updated if they get specifically targeted by a pull request. Also, changes to older branches aren’t regularly merged forward — although an individual change may be cherry-picked forward, depending on the nature of the fix.
