VM 8.1.90a

* This version contains an experimental feature of using IMAP
   folders in "headers-only" mode, with body loaded only on demand.
* New variable `vm-imap-refer-to-inbox-by-account-name' allows IMAP
   folders named "INBOX" to be referred to by their account names
   inside VM.
 * IMAP session dialogue restructured using UID queries, which makes
   VM more reliable in handling real-time changes on the server side.
 * New variable `vm-imap-connection-mode' can be set to 'offline to
   allow IMAP cache folders to be used offline. After connecting to
   the network, do `C-u M-x vm-imap-synchronize' to force full
   synchronization.
* New variable `vm-do-fcc-before-mime-encode' (formerly in
   vm-rfaddons) allows you to save fcc copies of messages before
   mime-encoding them.
* The right-mouse-button context menu for URL's in messages updated
   to eliminate obsolete web browsers. Entries added for Firefox,
   Mozilla and Opera.
* The function `vm-mouse-send-url-to-konqueror-new-browser' renamed
   to `vm-mouse-send-url-to-konqueror-new-window', to be consistent
   with other similar functions.
* New variables `vm-expunge-before-quit' and `vm-expunge-before-save'
  introduced to allow automatic expunge. They are nil by default.
