How this page is built

Every entry above is Blizzard Entertainment's own hotfix note, shown in full and in the order Blizzard posted it: nothing is summarised, paraphrased or added, and each date block links to the original article. The tracker reads Blizzard's official hotfix post every 30 minutes and keeps every date it has seen, so an older day stays here after it rolls off the article. Where a hotfix names a spell, item, boss, instance, zone, faction or achievement that has a page on this site, the name links to it; a name that could mean more than one record is left as plain text rather than guessed. A date with no hotfixes is simply absent.
