XML-RPC has been debugged and reorganized. Each API is now in its own file:
Blogger API debugged (fplanque)
blogger.newPost no longer requires a cat ID (<category>123</category>) to be passed. It will use the first/default cat available in the targetted blog.
b2 API debugged (fplanque)
MetaWeblog API debugged (fplanque)
Movable Type API debugged (fplanque)
Added Really Simple Discoverability (RSD) support (fplanque).
Better default install: The installer will now create the default blogs with cleaner URLs by default. We do believe these will work on 99% of the current Linux hosts. It is always possible to change the URL scheme in the Blog Settings.
