Contrary to some beginner's rumours, Gamestudio upgrades are of course always 100% compatible to their predecessors. We guarantee that all previously properly working projects will still work as before. All possible incompatibilites are mentioned in the update sheet.

BUT: The behavior can be different when there already was something wrong in the script before.

Some answers:

- GED does not start: Most likely caused by having old versions of the .c or .h include files in folders where they don't belong. Check for multiple copies, especially mtlFX.c in the code folder.

- Collision box is wrong: Check your code where you set it. If you can't find an obvious bug there, contact support with a test level so that they can look into it. Typical reasons of a wrong collision box are changing the entity scale or having entity frames with large size variations.

- Physics doesn't work - there's nothing changed with physics in this update. Again, if you can't see an obvious reason in your code, contact support with a test level.

- Bones rotate different - nothing changed here, they rotate just as before. Otherwise, see above.

- Particle_trail demo shows a horizontal stripe in the free version - we can't reproduce this here; does the stripe also appear when you remove the BEAM flag in the script?

If you think you found a real bug in this beta version, please contact Support or post a bug report.
