I've had my library pruned down to 25,000 tracks, sitting right at the limit for months, so I've been eagerly awaiting that rumored increase. It's always been easy for me to check, too, since trying to add even one track would throw an error. Well, I tried adding a few tracks again this morning and it didn't error, I had time to test again just now and I added about 100 more tracks with no error.
How about y'all? Is your 25,000 track cap gone?
