This version brings the following improvements:

When editing a chord name, a double click on a row of the Cached Chords Names table will be enough to select the chord and confirm it.
Added a keyboard shortcut to insert a double bar: F
MIDI playback: play legato slides without striking the second note.

Prevent System->Remove Staff from deleting the bar lines from the remaing staves of the system.

* Limit the length of helper lines in standard notation, to make them more pleasant when there are few positions in the sys
tem.
* Sometimes wrapping ties were not updated correctly when performing certain edit operations. Fixed.
* Prevent fermata symbols from overlapping on whole notes on the first notation line.
* Draw wrapping tie arcs for rhythm slashes too.
* Updated the Apple Remote support to work with Lion too.

- Improved readability of fret numbers in the tablature.
- Fixed playback of GuitarPro documents with only one score.

- When editing a barline, the beaming pattern can optionally be applied from the current bar to the end of the score.
- Improved copy & paste when working on a single staff.
- Preferences: added option to automatically create new sections. If set, a new empty section will be added upon entering a note on the last position of the last section of the score.

- Corrected the formula for diminished chords in the Chord Dictionary.
- The size of chord diagrams is configurable among the preferences.
- A couple of other minor fixes.

- The handling of dynamics in GP files has been improved.
- The play rate slider in the toolbar now shows the scaling factor too. Also, it's possible to click on the percentage to edit the value manually.

- Compatibility with GP5 files containing chord information has been improved.
- An option to use spacebar to toggle playback instead of inserting empty positions has been added to Preferences.

* Standard notation: in some cases, tie arcs were not drawn correctly. Fixed.
* Floating texts remain visible even when switching to tablature or standard notation only mode. Only those texts that would have appeared in the hidden parts won't be shown. Editing floating texts in these modes is still not supported.

* Fixed problems in the Guitar Pro importer.
* Improved the rendering of hammer-on/pull-off ties.

* Added an option to automatically insert barlines.
* Floating texts can be removed by dragging them out of the score.
* Pressing the alt key while starting to move a floating text will clone it.
* Pressing the shift key while moving a floating text will keep it aligned to its original position.
* Tuning dictionary: updated the tunings for banjos.
* Print has been tweaked to exploit the full printable area.
* Added keyboard shortcuts to toggle pick strokes down/up (k/K).

* Chord Dictionary: the panel can be resized.
* It's possible to click on the zoom value to edit it, for those who don't always like to use the slider.
* When editing a bend, "Release (gradual)" couldn't be set correctly. Fixed.
* Added a keyboard shortcut to toggle chord names (c).

Added support to read and save Unicode strings. This means that now you can use any character set you want (Japanese, Korean, Greek, etc…) and your texts won't be mangled upon saving.

Added some extra tunings (e.g. Violin) in the Choose Tuning list.

- Guitar tunings will be shown as reference in the tablature header.
- Remember the last used Display Mode when opening a new window.
- Standard notation: improved rendering of tie arcs so that they never overlap.
- Improved rendering of tablature symbols (e.g. picking stroke directions) when using a bigger-than-usual tablature font size.

* Fixed a crash occurring when changing the Tablature Staff/Chord Names properties on GuitarPro files.
* Make sure that the last remaining guitar in a score cannot be removed.

- Guitar In symbols could disappear when undoing a change to a system. Fixed.
- Improved stability when editing the tablature while playback is in progress.

Implemented a workaround for a Mac OS X/Xcode bug that caused some crashes while saving certain tablatures.

- Added option to change the size of chord names.
- Improved rendering in tablature-only display to prevent chord names to overlap with the first notation line.

- MIDI playback: the tempo slider can be used to speed the song up too (up to 2x faster than the tempo set in the document).
- Standard notation: extra notation lines could be drawn with an huge length, thus causing excessive slowdown, when a system contained many positions. Fixed.

- Chord Dictionary: disable the "Add to Score" button when no document is open.
- Disabled autosave on GuitarPro documents, to avoid problems. It's a good practice to convert GP docs to PowerTab before starting to edit them, anyway.
