Changes Since Previous Version Bug fixes Keyboard Preferences: Shortcuts for Generators, Effects and Analyzers were not exported. All imported shortcut changes were discarded. Equalization curves were corrupted in Graphic EQ mode after switching to/from Draw Curves or after running the effect then reopening it. Change Pitch displayed corrupted values when reducing pitch or editing "from" Frequency. Detection was very inaccurate at high sample rates. Bass Boost no longer clips if the track contains 32-bit audio. Auto Duck was excessively slow on older machines. (Windows) Exported MP3 comments tags were not seen by Windows programs. (Windows and OS X) Audacity crashed if you used system quit before file import was complete. (Linux) Equalization crashed Audacity if the XML file was corrupted. (Linux) When configuring effect parameters in "Edit Chains", "Preview" (not intended to be functional) caused a crash. (Linux) LICENSE.txt and README.txt were wrongly installed in /usr/local/share/doc instead of /usr/local/share/doc/audacity/ . Accessibility: ENTER did not toggle selectedness of a label track unless a label was selected. Numerous other interface fixes.
