+## Version 1.3.0
+Released on 20.12.2022
+
+### Breaking Changes
+None
+
 ### Bugfixes
 - NULL bytes in log messages are handled now and no longer lead to crashes of qudi. They are 
 replaced by the corresponding hex literal "\x00".
 - Rubberband selection of utility plot widgets now works for `pyqtgraph != 0.12.4`. This specific 
 version is broken in that regard and a comprehensive error is thrown if it is detected.
 - Adjusted 2D gaussian fit arguments to be compatible with the datafitting toolchain.
+
 ### New Features
 - Multiple qudi sessions can now be run in parallel locally. However, the user must ensure 
 non-conflicting socket server settings for namespace server and remote module server in the 
 configs to load.
 
 ### Other
 - Bumped minimum package requirement `pyqtgraph >= 0.13.0`.
+- Introduced properties to make `qudi.util.constraints.ScalarConstraint` mostly backwards 
+compatible with the deprecated `qudi.core.interface.ScalarConstraint`. Only exception is `unit`
+which should not be supported anymore.
