Hey all! It's been a while, but this is the update that a lot of you have been asking about and waiting for!
If you currently have it installed and wish to upgrade, be sure to uninstall the previous version(that is, run uninstall.bat) and then install(with install.bat) the latest download and it will work just as before for your .sai files but with new additional support for .sai2! In addition to this, I've also added some metadata to SaiThumbs.dll to help diagnose any issues people might be having with particular versions. This information may be very valuable to include when submitting bug reports!
If any particular .sai or .sai2 files seem to fail at creating a thumbnail, feel free to reach out so I can research any file format nuances I may have missed!
