This is embarrassing:

A few days after 5.2.β.1 release I found a silly bug. I fixed it and made a new release (5.2.β.1-1) but I forgot to update the GitHub mirror. I've commited the tatest changes today.

I'm not working with Allegro.pas because I'm focused in my game engine MinGRo. I need to finish a new version soon because I have a game commission that I should finish soon.
