User-facing changes

Interface changes

  • Vector is getting a huge update! - After more than a decade, Vector has reached a huge milestone with Vector 2022! This update to the Vector skin is the biggest ever and will mark a departure from Vector's classic look. The new refreshed skin will replace Vector as the new default for all wikis and will introduce some breaking changes so please be in anticipation for that. Users will still be able to move their wikis back to legacy Vector or set their global or local default skin as legacy Vector. For more information, please read Vector 2022's documentation page to prepare for this change.
