Exactly, I just wanted to write the same ;-)

This is because there was a compiler hack in Seaside 2.7 and earlier
were that is luckily not needed anymore in 2.8. Unfortunately loading
2.8 into a 2.7 removes some important methods from the compiler
causing the image to irrecoverably freeze. Before loading you need to
remove all the old Seaside extension methods from the Seaside package.
Unfortunately I don't see a simpler solution ...

To give an update on the status:

- Cleanup of WARoot, WADocument and friends.
- Tests and much more comments for WACanvas, WABrush and friends.
- Better and more efficient encoding of URLs and XHTML.
- Got rid of WAHtmlRenderer and all its former users.
- Removed unused code.

Still ongoing are the following tasks:

- We are working on major speed optimizations, depending on the
application Seaside 2.8 is already up to twice as fast as earlier
- I am currently investigation ways to reduce the per session memory
consumption. No figures available yet.
- The responsabilities of WARenderer, WARenderLoop, WASession,
WARenderingContrext are not clear. Especially the session contains a
lot of request related things, that should not be there.
- New implementation of state backtracking.
