+
+## Upcoming changes for server owners
+
+We are currently in the process of preparing a config merge, so that almost all of the config options currently split across the various Bukkit, Spigot, and Paper files finally go together. Our current plan is for this to land in the next major release, aka 26.4. You can track the current progress and changes here: https://github.com/PaperMC/Paper/issues/14304

+
+## Faster CI build times and deployment
+
+[Namespace](https://namespace.so/) are now sponsoring our CI runners! A lot of waiting time on Minecraft releases and commits in general came down to slow CI, and TeamCity configuration editing was also a fairly slow process whenever we moved or created version branches.
+With the switch, deployment of builds, API, and dev bundles has become significantly faster, and with our own efforts in parallel, has simplified internal processes around updating to new Minecraft versions.
+
+In the future, we also plan on making produced JAR files more tamper-proof, e.g. by signing them. The pull request workflows will also be made faster later.
+
+Next to the above, we have also decreased the distributed JAR file size by about 10mb!
+

+
+## For developers
+
+A lot of API that was previous marked as experimental, including most of the data component API, have had their experimental annotations removed!
+
+### Events for working with cushions
+
+We introduced [EntityBreakEvent](https://jd.papermc.io/paper/26.3/io/papermc/paper/event/entity/EntityBreakEvent.html) and [EntityBreakByEntityEvent](https://jd.papermc.io/paper/26.3/io/papermc/paper/event/entity/EntityBreakByEntityEvent.html), similar to the existing hanging break events. Next to that, you can use the pre-existing [EntityPlaceEvent](https://jd.papermc.io/paper/26.3/org/bukkit/event/entity/EntityPlaceEvent.html).
