-- `SliceValue` can now correctly be checked for equality: `SliceValue.equals()` and `SliceValue.hashCode()` are overwritten.
-- `TemporalValue.hashCode()` was overwritten, thus `equals` and `hashCode()` are in sync now.

 ### Added
 
 - Temporal Literal shows an error if two slices use the same point in time. The check can handle date literals and (nested) references to constants with a date literal. (See [PR 707](https://github.com/IETS3/iets3.opensource/pull/707))
 - Temporal Literal shows a warning if the point in time of a slice cannot be unwrapped to a date literal, rendering the duplicates-check mentioned above ineffective. (See [PR 707](https://github.com/IETS3/iets3.opensource/pull/707))
 
+### New language org.iets3.core.expr.typetags.bindingtime
+
+The language extends typetags with support for different binding times of values. Consistency checks ensure that information is passed on at appropriate levels.
+
 ### Fixed
 
 - Unit comparisons for the **same** unit defined in **different** packages now lead to an error message for compatibility

-- `IETS3ExprEvalHelper` methods no longer log exceptions that they re-throw. Some callers may ignore exceptions thrown by the interpreter, and having them logged unnecessarily clutters the logs. It is now the caller's responsibility to log exceptions where needed.
