Today we release Jaikoz 8.1, this is very much a bug fix release.
Remaining regressions from the Jaikoz 8 release have now been fixed
Manual Correct From MusicBrainz was not showing metadata matches, only acoustid matches - this is now resolved.
Match to Specified Release was no longer letting you override warnings about track durations and acoustid title matching. This has been fixed and extended to allow override when matching by Catalogue No or barcode as well.
Correct Metadata from MusicBrainz could fail if you had music files directly in your root folder (i.e / on OSX or C:\ in Windows), now fixed.
NullPointerException at Match to Specified MusicBrainz release if release has release date but not release country now fixed.
Further Performance and stability improvements
Jaikoz using more memory as songs are fixed, this regression was introduced in Jaikoz 8.0.2 as aprt of another fix.
Performance improvements have been for dealing with matching large releases.
