A new beta of Iris is now available for download.

Features:
- Improvements in the email editor; added default font (can be changed in settings)
- Connected servers will periodically poll for new messages
- Rewritten connection handling to improve performance and fix connection issues over time

This version also fixes:
- Switching between several displayable email compontents only worked once per component due to a bug in tmp file lookup
- Fixed an issue related to saving attachments from an email open in a separate window after the active folder has changed in the main window
- Improved server disconnection handling
- Fixed a crash in vmime related to IMAP folder access
- Unread messages count could sometimes be negative due to an overflow
- Fixed a long-standing reconnection problem where internal exception routing would skip over the actual reconnection routine
- Fixed an OAuth2 issue which caused servers to reject authentication if they weren't used for a long time (days) so that the refresh token expired - this delegates login back to the web browser as required by OAuth2
- Worked around an imap.wp.pl issue where the server returns messages in a random order instead of sorting them by uid
- Fixed a Sent folder refresh issue after sending an email
- Fixed a wrong UID count in folder issue causing server commands to fail after emptying a folder
