Since the release of the first Release Candidate a month ago, we've made a substantial number of revisions. These modifications are primarily focused on eliminating old code and enhancing the quality of the existing code.
Most of this work was done by Thomas Votruba from Rector who contributed an astounding 60+ pull requests to improve Mautic using Rector. Massive thanks to Thomas for this work.
There are also many bug fixes included in this release as well.
Given the broad nature of these revisions, it's critical that we perform more rigorous testing than usual to ensure stability, hence the decision to release an RC2.
Please read the release notes for further information and the accompanying blog post for details of this, and the upcoming General Availability release.
A big thanks to all our contributors who helped toward this release!
We invite you to help with testing the release and report any issues on Slack in #mautic-5 and/or GitHub, and to join us each Friday to help with testing new bug fixes, features and enhancements - we can't get things released in a timely manner without your help!
For guidance on how to test, check https://mau.tc/tester - it can be done in the browser and you don't even need to know how to install Mautic to get involved!
