Title: Roundcube 1.5 beta released
Post by: SKaero on March 05, 2021, 05:57:13 PM
We proudly announce the beta release for the next major version 1.5 of Roundcube webmail. With this milestone we introduce new features and long-awaited improvements. The most noteworthy additions are:

Adding support for PHP 8 required some deep refactoring of the Roundcube codebase which started with early PHP 5 versions. However, this refactoring also was a bit of a cleaning procedure and resulted in more testable components.

In case you’re running Roundcube directly from source or if you’re not using the complete package, you need to install 3rd party javascript modules using the bin/ script. With this release the toolchain required to build a functional package has changed a bit:

bin/ replaced google-closure-compiler with UglifyJS
bin/ replaced yuicompressor with csso
Elastic theme: require lessc >= 2.5.2 (and add support for v4) with less-plugin-clean-css

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. And don’t forget to backup your data before installing it. Download it from (

We also have some Docker images ( available for quick testing and evaluation.
