Currently, Bulbapedia tech is prioritizing addressing the following issues affecting user site navigation and experience:
A known issue of CentralAuth functionality affecting users and their ability to globally log into/link accounts
A known issue of the newly formatted RecentChanges design being completely broken. The old version has been set as default and users are encouraged to disable the new design in their preferences until we can fix it.
A full list of known issues related to the MediaWiki 1.35 upgrade, as well as features and updates on our progress of addressing them, can be found on our changelog. The changelog talk page may be used to report many new issues that have not been recorded so our tech can work to address them as soon as possible.
More updates to come!
