+### Highlights
+
+- Skeleton and volume tracings will be more unified, resulting in hybrid tracings that can contain both structures:
+  - Hybrid tracings are now enabled by default. They allow to combine the functionality of skeleton and volume annotations in one tracing. [#3399](https://github.com/scalableminds/webknossos/pull/3399)
+  - Old volume tracing versions now also can be restored. Access it through the dropdown next to the Save button. [#3349](https://github.com/scalableminds/webknossos/pull/3349)
+- The tracing view was improved:
+  - The info tab in tracing views now displays the extent of the current dataset. [#3371](https://github.com/scalableminds/webknossos/pull/3371).
+  - A User can now have multiple layouts for tracing views. [#3299](https://github.com/scalableminds/webknossos/pull/3299)
+  - More layouting improvements: [#3256](https://github.com/scalableminds/webknossos/pull/3256) [#3256](https://github.com/scalableminds/webknossos/pull/3256) [#3272](https://github.com/scalableminds/webknossos/pull/3272)

 - Some config keys have changed, if you overwrite them in your setup, please adapt: the `oxalis` prefix is renamed to `webKnossos` so the new keys are `webKnossos.user.time.tracingPauseInSeconds`, `webKnossos.tasks.maxOpenPerUser`, `webKnossos.newOrganizationMailingList` as well as `datastore.webKnossos.uri`, `datastore.webKnossos.secured`, `datastore.webKnossos.pingIntervalMinutes` for the data store.
 - There is now a separate module for the tracingstore, the datastore is no longer responsible for saving tracings. This module can run as a standalone application, or as a module of webKnossos locally. It is recommended that you choose the option that was previously also in place for datastores. In case of a standalone datastore, the local one needs to be disabled in application.conf: `tracingstore.enabled = false` and `play.modules.disabled += "com.scalableminds.braingames.datastore.TracingStoreModule` – and in either case, the adress of the tracingstore (localhost or remote) needs to be inserted in the db in `webknossos.tracingStores`.
 - The FossilDB version has changed from `0.1.10` to `0.1.14`.
