Hi there !
We decided to maintain a Central site and a development blog for calibre2opds, and here it is.
Here, we’ll talk about upcoming features and publish official releases. This site will also act as the central site giving links to where you can download calibre2opds and get support for calibre2opds.
If you have questions about calibre2opds then please use either the calibre2opds forum or to the Calibre forum. Questions asked here as comments tend to get missed.
