Hi.
I upgraded to the CVS-version of mediawiki yesterday and all seemed very fine, but sub-section editing is broken.
When editing a subsection in a wikipage, the result is that only that section is left on the entire page afterwards.
Thanks
Jesper
This might be a diff3 version problem. I had similar problems (pages getting blanked on edit conflict, and subection editing leaving just the subsection) before I switched mediawiki from using Sun's diff3 to gnu diff3.
