+### Changed
+
+- Upgrade to QUDT 3.1.4
+  - Calculation of scalings and factor units now happens in QUDT (see PR [1129](https://github.com/qudt/qudt-public-repo/pull/1129))
+    However, a few things have changed:
+    - rename `qudt:isScalingOf` to `qudt:scalingOf`
+    - rename `qudt:factorUnit/qudt:unit` to `qudt:hasFactorUnit/qudt:hasUnit`
+  - Currency units have changed:
+    - they were moved back into the graph 'http://qudt.org/vocab/unit/'
+    - their localnames have received the prefix `CCY_`
+    - both changes are 'soft', ie, the old way is still available, but deprecated
+    - for example: `http://qudt.org/vocab/currency/EUR` is now `http://qudt.org/vocab/unit/CCY_EUR`.
+    - QUDTLib makes the change now instead of adopting the deprecation, as there are other breaking changes as well, so upgrading will require work anyway.
+    - for QUDTLib constants, this means that the pattern `${CurrencyName}_Currency` is dropped in favor of the QUDT style `CCY_${CurrencyName}`, e.g. `Qudt.Units.EUR_Currency` becomes `Qudt.Units.CCY_EUR`
+  - Many conversion multipliers were changed in QUDT. They now consistently have at most 34 significant digits (ie, BigDecimal's precision of 34). This fixes problems such as the one reported in [Conversion error from MilliSV**PER**HR to MicroSV**PER**HR](https://github.com/qudtlib/qudtlib-java/issues/109).
+  - scalings of `unit:GM` deserve special mention:
+    - in the upcoming QUDT release we have `unit:GM qudt:scalingOf unit:KiloGM`, making `qudt:scalingOf` and `qudt:conversionMultiplier` consistent in all cases
+    - QUDTLib makes the change as well, with the effect that unit factorization does not use `Units.GM` (which probably surprised a few people) for the mass dimension but `Units.KiloGM` (which is what one would expect)
+
