HotFix. Basically it's when the game developer needs to release an emergency patch to fix a show-stopper bug in the game within the same release version.
Hotfixes should be extremely rare (preference to not happen at all). A game relying on these frequently is a sign of a bad development process in place or management has allowed scope creep to reach a unmanageable level.
If you're having problems with the latest trainer, try the other 2 version 1.10 trainers as you may not have received said HF for the game.
