   - All fixed done in version 2.3.8
   - CPPCHECK updated to 1.85
 
+## Version 2.4.5 (to be released)
+
+For users:
+  - Fixed an inconsistency in parsing of braces.
+    It is now possible to pass individual options
+    including spaces (e.g. with `FILE={/path with space/file}`). Notice 
+    that this invalidates syntax such as `ATOMS={1}{2}{3}{4}`. See more
