After almost pulling my hair out wondering why encodes with the exp7-merged branch were coming out bit-identical, I finally realized that the only changes were for CELT frames. Mine, at 96 kbps, are never getting anywhere near that low, so they're never hitting the analysis at all. At 192, I would expect the decodes to be bit-identical; you might want to test that before spending too much time abxing. The other changes since have just been minor bugfixes.
Actually, the changes in exp_analysis7 (which are now in master) do affect 96 kb/s. If you're seeing bit-identical output, you're doing something wrong.
Not sure which, but I swear I ran the exact same conversions this morning as yesterday, and today the exp branch is hugely different on the same songs. (120kbps vs 97kbps on one track, 65 vs 94 on another.) Yesterday, only the library name and frame headers were different at all. I built it myself a few times and didn't change anything but the bitrates in FB's converter, even checked the process command lines in process explorer; but whatever, it is obviously doing something now.
