For completeness: using the new version of plugin_mirrors.py on windows I get:
Code:
{"name": "KoboTouchExtended",
"description": "ePub features.",
"supported_platforms": ["windows", "osx", "linux"],
"version": [3, 5, 2],
"author": "Joel Goguen",
"minimum_calibre_version": [5, 0, 0]}
As far as I can tell this is correct. The new version also appears in the plugin updates dialog.
Clearly I was wrong about the indirection.
