After TortoiseSVN bugged me to update, i downloaded a new installer and ran it. It still works fine now, though it does not properly display icon overlays (despite that option being on in the settings). How can i fix it?
If you've just updated to 1.6.8 (as I have), you might have to do a repair install to fix the icon overlay issue. As detailed on the TortoiseSVN blog here.
