Over 30% of my library is AAC or Apple Lossless files, so seeing 'm4a' in the release notes made me jump especially quick to install this particular update.
This is why detailed release notes are good...
ClrCreekRdr, are you SURE these looping problems aren't also apparent in 2.6.7?
I had MANY occasions where I would load a track in 2.6.7, and the analysed BPM displayed in the library would suddenly be rounded to the nearest whole number in the beatgrid panel on the deck itself. This would throw out all my grids completely.
I could fix it by trashing the grid, then pushing Auto; then the correct BPM would be restored.
