The setting "Compilations: Group compilation albums together" on the "Music Library" tab stopped working in v7.1 beta 21605 (7/9/08) and is still broken in the latest nightly build: 21662 (7/12/08).

When I install the beta 21605 or 21662, the artist list under "Home->Music Library->Artists" displays 575 different artists (all artists from compilation albums incorrectly appear in the list). The status on the bottom of the page says "1246 albums with 14442 songs by 575 artists."

When I revert to beta 21576 (7/8/08), or any older version, this works correctly and as expeted. The artist list only has 322 artists and the status on the bottom of the page says "1246 albums with 14442 songs by 322 artists."
