Changes in this release:- Add ability to remove embedded fonts
- Add ability to update the metadata (including cover)
- Add an error dialog if the user clicks ok with no options selected
- Ensure rebuilding the ePub uses the Calibre zip code as per change to Tweak ePub
Note the problem one of you have reported with rebuilding the zip file (for an ePub containing a file with no timestamp) will continue to exist until the next Calibre release. Kovid has fixed it in the Calibre source code if you run from that. Alternatively you could use Tweak ePub, edit the file with no timestamp so it now has one and then rebuild it. Note this problem "should" be fairly rare anyway so hopefully won't stop you testing in the meantime.
@Paul - here is the embedded fonts change for you to test (thx for the donation btw). And no, this will not appear in plugin updater until I officially release it as 1.0 in the plugin forums and add it to the plugin index thread. So you will have to install it "old school" using Preferences->Plugins->Add.
I consider the plugin "stable" in that I quite happily run it against my own ePubs. However the feature list for it is still evolving and I greatly appreciate feedback on this thread from the early adopters about its usability from trying the betas.
The new "Update metadata" feature is rather more useful than I had hoped thanks to Kovid pointing me at some Calibre code I could reuse that does the hard work. It will update both the metadata in the manifest and the cover if possible, in the same way as when you send to device/save to disk. The same cover update limitation applies as discussed earlier in this thread (in that Calibre has to be able to identify the cover from the manifest, most easily guaranteed from a past conversion). The future todo list still has an option for this plugin to "Add a cover" to cater for "other" ePubs without requiring the conversion.
