 ### Fixed
  - Obfuscate the admin email address at the bottom of every page - we missed it in v0.22-beta1 (but got every other one though :P)
  - Bugfix: Don't use `->text()` for recursion when parsing markdown - it resets `->DefinitionData`, which breaks footnotes
+ - Fix name of did you mean index: `didyoumeaninddex.sqlite` → `didyoumeanindex.sqlite` (feature is disabled by default; manual renaming required)
 
 ### Changed
  - Disable parser cache by default to avoid issues because said cache isn't invalidated when it should be (and doing so would take more of a performance hit than leaving it on)
