If you want to use the generated catalog with Stanza you now need to specify Stanza in the Compatibility settings. This is because Stanza does not comply with the latest release of the OPDS standard (but only an earlier draft standard) and the default is for calibre2opds to generate a OPDS compliant catalog. This has been reported to Lexcycle, so we hope that in a future Stanza release the official standard may be supported.
If this is not clear in the
calibre2opds online documentation then please point out where it could be improved. (or make the change yourself as it is done as a wiki).
