Migrating from one GTK+ 3 release to another: GTK+ 3 Reference Manual

## Migrating from one GTK+ 3 release to another

GTK+ 3 has seen considerable development over multiple stable releases. While we try to maintain compatibility as far as possible, some minor adjustments may be necessary when moving an application from one release of GTK+ 3 to the next.

The following sections list noteworthy changes in GTK+ 3.x release that may or may not require applications to be updated.
