+### Changed
+
+- Variability: The performance of opening big variant configurations in editor has been improved (by switching off editor hints which are not needed).
+- Variability: The class hierarchy implementing `IRenamer` has been improved and documented. This interface is being used for tailoring the renaming behavior of the variability filtering algorithms.
+- Variability: Remove deprecated concepts `FeatureModelConfiguration_old`, and all related concepts. These concepts have been introduced when one proto-language for variability has been split into two languages, one for feature models and one for configurations. This happened end of 2024, and the deprecation window is now closing.
+
+### Fixed
+- Add missing deps. to SBOM
+- Add missing dependencies to build scripts

- The precision of number types with prefixed units (e.g. `mW` or `km`) was always set to `infinite` by the typesystem. Now, the precision is as precise as possible.
- Variability: Viewer for skeleton trees has been improved (better error reporting, more stable, does not break on nodes which are string literals).
- ShortLambda Interpreter: Fixed a bug which resulted in a `RuntimeErrorType` when interpreting ShortLambdas.
+- InterpreterCoverageAssResult: fix unique ID calculation ([#1617](https://github.com/IETS3/iets3.opensource/issues/1617))
