Subversion is getting closer and closer to something I want to use. Now with 1.1 you can backend a subversion repository (what svn developers call a "filesystem") on the Unix filesystem (instead of BerkelyDB). This reduces the install requirements and complexity—for most projects I think it's the better choice.

Also, the release notes paint a much more palatable picture about possible api and storage format changes. Prior to 1.0, the subversion code has been subject to pretty major changes between releases (as you would imagine for a pre-1.0 product).
