A new release of Tablatures is available.
The most important addition in this release is a basic and experimental* support for GuitarPro 3-5 files (*.gp3, *.gp4, *.gp5). GP tablatures can be read, but they will be converted to PowerTab when saved, keeping only the first two scores since that is PTB’s limit.
* this means that some files may not work. Feel free to report any problem you find.
