Hi Avishai,
Aside from the normal updates required to keep TestAdvantage inline with NetAdvantage of a similar release, the only change that may possibly affect you would be the error messages were changed. They will still be thrown at the same time, but if you have checks that examine the specific text of an error message, those tests may no longer respond as intended. This was done across the board to all actions, for all controls, and every error message thrown between TestAdvantage versions 8.1 and 8.2. Some may have ended up being identical to the previous error message, this was done to standardize the errors, across all controls.
