 ## [Unreleased/Snapshot]
 
 ### Added
-- Added implicit classes for `loactiontec.jts` Geometries that represent geographical geometries with functionality before located in `GeoUtils` [#163] (https://github.com/ie3-institute/PowerSystemUtils/issues/163)
+- Added implicit classes for `loactiontec.jts` Geometries that represent geographical geometries with functionality before located in `GeoUtils` [#163](https://github.com/ie3-institute/PowerSystemUtils/issues/163)
 - `OsmEntity` and `OsmContainer` to provide a simple, lightweight representation of openstreetmap data
-- QuantityUtils previously implemented in SIMONA [#288] (https://github.com/ie3-institute/PowerSystemUtils/issues/288)
+- QuantityUtils previously implemented in SIMONA [#288](https://github.com/ie3-institute/PowerSystemUtils/issues/288)
 
 ### Changed
-- Refactored `GeoUtils`, moved them to the scala package and tailored them toward the `loactiontec.jts` Geometries used in the `OsmContainer` [#163] (https://github.com/ie3-institute/PowerSystemUtils/issues/163)
-- Changed unit symbols according to DIN 1301-1 for apparent and reactive power [#278] (https://github.com/ie3-institute/PowerSystemUtils/issues/278)

+- Rounding for quantities is now part of the `RichQuantity` [#314](https://github.com/ie3-institute/PowerSystemUtils/issues/314)
 
 ### Fixed
 - Fix tests in CI [#206](https://github.com/ie3-institute/PowerSystemUtils/issues/206)
