Ardour 5.10 released

We are pleased to announce the availability of Ardour 5.10. This is primarily a bug-fix release, with several important fixes for recent selection/cut/copy/paste regressions along with fixes for many long standing issues large and small.

This release also sees the arrival of VCA slave automation, along with improvements in overall VCA master/slave behaviour. There are also significant extensions to Ardour's OSC support.
