An improved version of Flat's in-house model now powers every PDF and photo import, in particular:

• Multi-voice passages with shared rests and invisible rests are now supported.
• Barlines and repeat endings (voltas) are now placed correctly within measures.
• Beams are recognized more reliably.
• Time signatures drawn across several staves, as on orchestral scores, are now recognized.
• Fixed some chord symbols that were exported to MusicXML with a non-standard chord type.
