v2.2.0 New API v3:


  • Various stability improvements
  • Fix for Qt5WebSockets.dll not loading from dlls
    • Delete any old copy in the root directory if you are upgrading an existing install

v2.2.0 Dev Build 10 - NEW API:


  • Rewritten API to use the brand new Nexus API
    • You must reauthenticate within the Settings Nexus tab
      • You no longer enter user credentials, instead you will see a button. Click this button and you will be redirected to Nexus where it will ask you to log in and then authenticate the request for MO2. Once this is done MO2 will automatically receive and store your API key. If you revoke this key on Nexus, you will need to click the button to revoke your local credentials and then request a new key.
    • Requests are (currently) limited to 2500 a day and 100 per hour. (They are consumed simultaneously.)
      • Your currently remaining requests as well as the count of currently queued requests are now displayed at the bottom of the Mod list.
    • MO2 will now gradually scan 10 mods every 5 minutes - though you can still force check all mods if desired
      • This scan will prioritize mods that were least-recently checked for updates
    • Mods track the last update and will not fetch new data until an hour has passed
      • This info is visible in the version tooltip in the mod list, and the versions will be italicized when they are due for an update
    • Version info now uses author-defined file updates to help locate 'correct' update paths
      • If we find a file update and it isn't flagged as old or deleted, we 'prefer' that update version
    • The file category (main, update, old, deleted...) is now used to determine if a mod is outdated
  • Credential storage has been migrated to a more secure encryption scheme which is tied to your Windows account
  • Did I miss anything? Maybe!

  • Fixed Enderal plugin
    • Warning: Until Enderal team does not release an update the game will be unable to read the MO2 plugins.txt, instead reading the one in Appdata/Local/enderal due to an incompatibility with USVFS and SkyrimRedirector.dll. They are on it.
  • Fixed saving data related to profile-specific save games

    • Each word does not have to match a full word, searching "static improvement" will match "StaticMeshImprovements".
    • By using keywords (OR || | ;) the search can be divided in OR segments (OR wins over AND).
  • Added link to discord and documentation to help menu.
  • Added Parchment theme by TheBobAbides.
