So what's new with v0.20, aside from a couple of tweaks and fixes? Apparently, the v0.11 which we missed already introduced 5.00 M33 support! Here's the full changelog history (translated) from the initial v0.10 release:
* ver.0.20: MS-free space does not write the file to fix bugs. Add Error Logging feature set.
* ver.0.11: CFW5.00M33-3 supported.
* ver.0.10: open for now.
