I just upgraded koha to v.2.2.6 on windows.  Attached is the opac screen.  Note that some of the features available to 2.2.5 are missing:

 

Member cardlog in (for member to log in to their account using their member ID#)

After a book is retrieved, the option to Request a book, hold etc, vitual bookshelf...

 

Were those features done away with in v.2.2.6?
