Sorry, but there is a bug in the 1.2 that can cause problems with position with blocked pawns structure.
There is the update 1.2b available https://sites.google.com/site/mdannib/download

If you run games only between the new version and the old one; have you tried with other opponents like stockfish?

But I only wonder why they still use Gull 1.2 when there is Gull 2

The new version 1.2c is ready; this is a bug fixing release.

The change log :
- Fixed the bug that cause random crashes during endgame (thanks Ingo)
- Fixed time manager bug that occurs on long time control
- Fixed an annoying bug that "freeze" the engine at 7ply on certain positions
- Tuned evaluation
- Tuned the limit strength feature (too weak compared to the elo settings)
- Fixed misevaluation due to pawn blockages on some positions

Regards,
/Matteo & Maurizio
