No, there is no overlap, 9.1.0 will be the next 9.0.x in the (mostly) monthly release schedule. So let's say March 2027 sees the release of 9.0.128 (give or take a few increments). 9.1.0 would then be released in April, and 9.0 would then be EOLed according to the plan. > 2. > > *Upgrade considerations (9.0 → 9.1)* > - Are there any *major behavioral, compatibility, or configuration > changes* that users currently on Tomcat 9.0.x should be aware of when > planning a move to 9.1.x?

The only change is listed: removal of the APR connector and move to tomcat-native 2.0. Tomcat 9.0 is the only branch still with APR and sometimes we do get very complex bug reports on it. 9.1 will support the same EE APIs as Tomcat 9.0, and no other breaking changes are expected. Initially we had more ambitious plans like upgrading the Java versions and such, but the feedback on that was negative, with some pointing that the move off Java 8 would mean as much work/trouble/expense as the move to Jakarta EE. > 3. > > *Support and lifecycle changes* > - Are there any *changes in support terms, maintenance policies, or > lifecycle expectations* between 9.0.x and 9.1.x that users should > factor into long‑term planning? > - Any guidance on recommended upgrade windows or best practices would > be helpful. It is possible the eventual EOL for Tomcat 9.1, which has not been announced yet and may still change, may be aligned with the Java 8 EOL from "normal" community sources (for example, for Temurin that I use for building, it is announced as "December 2030 for Eclipse Temurin"). Nothing has been announced and this is only a personal consideration. > For our context, *Tomcat 10.x involves a Jakarta EE–based namespace and > significant structural changes*, which requires notable application‑level > work.
