M6 is out, and you can get it here. Right now there are only Win32 and Linux builds, but others can't be far behind.
Release notes are here.
Thanks to Henrik Lynggaard and sj12fn for the news.
The rendering engine is not slow at all. The reason it takes so long to flow in your case is probably because of the UI.... Try viewer, and you'll see the fastest rendering engine available. Especially on nested tables (it's hellishly fast at computing nested tables, and even up to at least 10 levels is perceivably instantaneous).
What specifically is not appearing quickly for you? It may be a bug that you should file with Bugzilla.
