The release notes (http://subversion.tigris.org/svn_1.6_releasenotes.html
) will contain an overview of the new features to expect. As the
release gets closer, the page will get fleshed out a bit. There are a
couple of features which I like so much, I've been running nightly
builds for the last few months.

There are a number of new features in 1.6, some of which are user-
visible, others which are not as visible. The Subversion community is
trying hard to do more frequent minor releases, in an effort to cut
down on the amount of new stuff in each release. This makes
development more manageable, decreases the new testing surface area,
and hopefully gives users access to more features more frequently.
Compared to the almost 2-year cycle for 1.5, 9 months for 1.6 is quite

Understood, which is why we're working hard to get wc-ng ready for
1.7. I think we'd all like to have a faster working copy library.
Unfortunately, the design has been completed for quite some time, but
only in the last few months have developers shown interested in
implementing it. Help is always appreciated!
