I've also established a mailing list for jTab. All are welcome to join in to discuss internal development issues, usage, and ideas for enhancement.
Some of the key new features:
- All chords can be represented in any position on the fretboard e.g. Cm7 Cm7:3 Cm7:6
- Now allows shorthand tab entry of 6-string chords e.g. X02220 (A chord at nut), 184.108.40.206.8.8 (C chord at the 8th fret)
- jTab diagrams now inherit foreground and background color of the enclosing HTML element
- When entering single-string tab, can reference strings by number (1-6) or by note in standard tuning (EAGDBe)
- The chord library with fingerings has been extended to cover pretty much all common - and uncommon - chord variants (m, 6, m6, 69, 7, m7, maj7, 7b5, 7#5, m7b5, 7b9, 9, m9, maj9, add9, 13, sus2, sus4, dim, dim7, aug).
- It has been integrated with TiddlyWiki: jTabTwiki combines the guitar chord and tab notation power of jTab with the very popular TiddlyWiki single-file wiki software. Together, they allow you to instantly setup a personal guitar tab wiki/notebook. No kidding. And it's free.
