As to my knowledge, the A5 template scripts still work with A7 and A8. They are still included in the template_5 folder of the A7 version.

The quake water blocks from A4/A5 are not supported anymore since A7. Use passable terrain for water. You have then the choice between the old quake turbulence shader or the reflection shaders. Shaders are not supported by the free version, so you need Commercial for a real water effect. In the free version you could only use a transparent surface with a texture animation or a drift.

Also, the old A5/A6 block maps are not supported anymore since A7. But this should not be a problem, just recompile them to A7 mesh maps.
