# Cyrus IMAP 3.1.0-dev Release Notes

Unavailable for download as this is a development branch only.

Access is via git.

## Major changes since the 3.0.x series

## Updates to default configuration

- The specialusealways option is now enabled by default. It must explicitly be disabled for interoperability with legacy clients that can’t handle RFC 6154 attributes in extended LIST commands.
- The per-user calendar and addressbook administrative web user interfaces (e.g. /dav/calendars/user/<userid>) are now disabled by default. They can be enabled with the caldav_allowcalendaradmin and carddav_allowaddressbookadmin options respectively.
