We're proud to announce that TortoiseSVN 1.7.1 has been released. It is linked against Subversion 1.7.1
It's only been a few days since we released 1.7.0, but in this time we've fixed a lot of bugs. Both in TortoiseSVN and the underlying SVN library.
We recommend that you update to this version as soon as possible. You can get it from our download page.
