A new command View->Line Numbers has been added. Opening a large session with many documents is much faster. Missing icon theme index files in the source tarball have been fixed. A Python snippet can define a main() function with more power than just setting the 'text' variable. The user interface no longer blocks anymore when LilyPond is started to read some information (which, especially on Windows, could take a long time when it is the first LilyPond run), and the built-in manual now also documents the settings and session dialogs.
A pager for the music view has been added. The Home key now has "smart" behaviour. Shift+Return no longer enters a line separator anymore, which could cause incorrect point and click locations. A new Brazilian translation has been added. Various bugs have been fixed.
Some bugs were fixed, mostly related to the handling of filenames with accented letters under MS Windows. A fully self-contained Windows installer has been created, so that installing Python, PyQt4 etc. beforehand is no longer needed on Windows.
Frescobaldi 2.0 is a full rewrite of the application. It does not depend on the KDE4 libraries anymore, enabling it to run on all platforms supported by Python and PyQt4. Major improvements include two-way point-and-click, a built-in MIDI player and a snippet manager, which can now also run templates and user-written scripts.
