Dear subscribers

We proudly announce the beta release for the next major version 1.6 of Roundcube webmail.

With this milestone we cleaned up the code and bring full support for PHP 8.1. The most noteworthy changes are:

PHP 8.1 support
Dropped support for PHP < 7.3
Support responses (snippets) in HTML format
Option to purge deleted mails older than 30, 60 or 90 days
Unified and simplified services connection config options
Removed the Classic and Larry skins from the release packages
SQLite: Use foreign keys, require SQLite >= 3.6.19

Adding support for PHP 8.1 again required some refactoring of the Roundcube codebase and removing/replacing now deprecated PHP code. We also used this cleaning efforts and simplified Roundcube's config options a bit.

Breaking Changes

Some config options have either been removed or renamed. Read the details in the release announcement on our website or in the release notes.

If you used the Larry or the Classic skin in your deployment, you need to install them manually as they are no longer part of the release packages. They can easily be installed via Composer. See the full changelog in the release notes on the Github download page.

This is a beta release and we recommend to test it on a separate environment. Download it from roundcube.net. Migrate existing configs with either the installto.sh or the update.sh scripts. And don't forget to backup your data before installing it.

Cheers,

Thomas & Alec
