Qtractor 0.6.1 发布了，改进记录：
A new user preference option has been added on whether to hold auto-scrolling while making edits.
Color chooser dialogs were missing their proper titles.
Audio peak file re-generation and clean-up has been hopefully fixed and cache-optimized for drawing audio clip wave-forms.
The initial session snap-per-beat setting on the main toolbar has been fixed.
Exported clip files are now made persistent.
A Portuguese (pt) translation is added
