## ChangeLog

- Apr 30, 2020: initial release.

## General (All backends should apply these changes)

### Update `/etc/iredmail-release` with new iRedMail version number

iRedMail stores the release version in `/etc/iredmail-release` after installation, it's recommended to update this file after you upgraded iRedMail, so that you can know which version of iRedMail you're running. For example:

    1.2.1

### Upgrade Roundcube webmail to the latest stable release (1.4.4)

Roundcube 1.4

Since Roundcube 1.3, at least PHP 5.4 is required. If your server is running PHP 5.3 and cannot upgrade to 5.4, please upgrade Roundcube the latest 1.2 branch instead.

Roundcube 1.4.4 fixes few security issues, all users are encouraged to upgrade as soon as possible.
