UOAssist.dll - Oct 9, 2022
  • Made it so enchanted apples and greater conflag potions were known to be stackable so the resource counter worked with them.
UOAssist.exe 1.9.1 - Jun 22, 2018
  • Changed how access to updateace.dll took place so it didn't appear to be virus like.
  • Now passes all but 3 of the virus checkers on virustotal.com - will look into submitting it to them to get it listed as clean.
  • Because of the way UOAssist works (adding itself to UO) it is virus like which sometimes gets it flagged.  And even though that code did not change between 1.8.5 to 1.9.0 more virus checkers started flagging it.  Really the only thing I know that changed in that code was newer compilers.
UOAssist.exe 1.9.0 - Jun 17, 2018
  • Updated embedded UpdateAce.dll to better support ads.
  • Updater news page now is loaded from https://www.tugsoft.com/uoassist/news
  • Changed server names from updateace.com to tugsoft.com to help with SSL issues on XP.
UOAssist.dll - Dec 20, 2016
  • Fixed a problem with trial dates after 2016 not working.
UOAssist.dll - Jul 23, 2016
  • Fixed a buffering problem that could cause the client to get out of sync with the server.  This normally manifest it self when portaling/logging in to a place that had a lot of items/npc's/player (objects) in the area so the client received a lot of information all at once.
UOAssist.dll - Mar 27, 2016
  • Made changes to the updater and uoassist.dll to hopefully overcome the problem when logging in and UOAssist didn't correctly figure out what server the character was on.
