TortoiseSVN 1.6.8 has been released.
This is a bugfix release/maintenance release, linked with Subversion 1.6.11.
This release also contains several adjustments to make TortoiseSVN work better on Windows 7.
We recommend that you update your TortoiseSVN client to this latest version. You can get it from our download page.
You might have to do a repair install (start the installer again, then choose 'repair') after you've updated to 1.6.8. Otherwise the overlay icons might not show up properly. Sorry for the inconvenience.
