any reason why the "displayurl" element is not listed in plugins_win.json?

[Bernhard Bauer, 2011/11/30 14:29:23]

Oops, this line shouldn't be in here. For now, all the Mac plugins use
displayurl, until the plugin installation functionality is ported (and we have
direct download URLs). For Windows, the URLs are for direct download, so we
don't use displayurl there.

[Bernhard Bauer, 2011/12/01 10:20:56]

Done.
