Roundcube 1.6 beta released

We proudly announce the beta release for the next major version 1.6 of Roundcube webmail. With this milestone we cleaned up the codebase 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

The following config options have either been removed or renamed:

1. IMAP:
   • renamed default_host to imap_host
   • removed default_port option (non-standard port can be set via imap_host)
   • set “localhost:143” as a default for imap_host
2. SMTP:
   • renamed smtp_server to smtp_host
   • removed smtp_port option (non-standard port can be set via smtp_host)
   • set “localhost:587” as a default for smtp_host
3. LDAP:
   • removed port option from ldap_public array (non-standard port can be set via host)
   • removed use_tls option from ldap_public array (use tls:// prefix in host)
4. Managesieve:
   • removed managesieve_port option (non-standard port can be set via managesieve_host)
   • removed managesieve_usetls option (tls:// prefix in managesieve_host have to be used)

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:

$ composer require roundcube/larry

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.
