TortoiseSVN 1.6.10 has been released.
This is a bugfix release/maintenance release, still linked with Subversion 1.6.12.
Apart from a few bugfixes, this release also works again on Windows 2000 and XP SP2 and earlier. Version 1.6.9 required at least XP with SP3.
We recommend that you update your TortoiseSVN client to this latest version. You can get it from our download page.
Also note that after installing this version, you have to run a repair install. To do that, run the installer again and click the "Repair" button. I'm sorry about the inconvenience.
If you want to know why the repair install is required, you can read about the technical details in my earlier post.
