OK, so here's another small update.
This is mostly a cosmetic fix to version 2.1.0, there are no functional changes to the JBPatch core.
This release also includes an updated version of the password patch. As aditya3089 pointed out in a PM, the password protection previously wasn't effective if the "Go To..." item was selected on the details screen (@aditya: thanks for the hint!) This is fixed now.
It's not strictly necessary to update to this version - if you're using the password patch, you could also just update the patch and keep using 2.1.0.
Oh BTW, I just noticed that password-protection also works for collections (FW 5.1.2)!
