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.

General

• Improve continuous integration (#1180, #1182), move from Travis CI to Github Actions (#1086, #1097, #1098, #1161)
• Modernizations: remove Mutex (#1095, #1127, #1128), typing system (#1172, #1176)
• Allow building with newer compilers (#1134, #1137, #1145, #1206, #1208, #1210, #1211)
• Build python3 by default, not python2 (#1209)
