+# 3.5.0
+
+## Highlights
+
+Apart from many bug fixes and modernizations, a few new features were introduced:
+
+ - TaQL now supports copying columns to new columns (e.g. to make a backup of the `FLAG` column)
+ - Non-zero coordinates in JPL frames, e.g. the `SUN` frame, are now interpreted as an offset in right ascension and declination. Previously, coordinates in a  JPL coordinate frame were ignored.
+ - The Dysco storage manager is now built by default as part of casacore.
