+===============================
+
+2.1.0
+-----
+
+### Fixed issues and related features
+* You can find issues and feature requests related to this release on our
+  [roadmap](https://github.com/Icinga/icingaweb2-module-businessprocess/milestone/4?closed=1)
+
+### Usability and visualization
+* Missing nodes are now shown in a generic error notice
+* `Unbound nodes` (nodes not being shown at top level and not in use as a sub
+  node) are now reachable through a fake node
+* A bug with the Chrome browser showing messed up checkboxes has been fixed
+
+### State calculation
+* Missing nodes are now considered being `UNKNOWN` (or `UNREACHABLE` when
+  being a host node). The former behaviour comes from Icinga 1.x, as a reload
+  there had the potential to trigger false alarms. This is no longer an issue
+  with Icinga 2.x, allowing us to be strict once again when it goes to missing
+  nodes
+* Linking nodes from other process configuration files (still an undocumented
+  feature) has been broken shortly before 2.0.0, this has now been fixed
+
+### Permissions
+* Permissions have not been enforced as they should have been in 2.0.0, some
+  links and operations have been accessible to roles that haven't been granted
+  such. This has now been fixed
+* While we allow for granular permissions that can be persisted in every process
+  configuration file (still an undocumented feature), there is now also a pretty
+  simple but effective way of restricting access to your business processes based
+  on process name prefixes.
+
+2.0.0
+-----
+
+* First officially stable version
