Redmine 4.2 – Review

Redmine 4.2: Novelties and Improvements

Recently the Redmine development community released version 4.2.1 of our favorite project and task management application.

In Redmine versions 4.2.0 and 4.2.1, more than 200 tasks have been carried out to improve the platform, including new features, patches and bug fixes.

The most relevant improvements of these latest versions are listed below:

Accounts and security

  • 2FA authentication (#1237): as can be seen from the very low number of the issue, this functionality has been in demand for some time. Especially interesting in installations where sensitive organizational data is managed.
  • configuration of allowed or disallowed email domains (this allows e.g. only users from certain domains to register) (#3369)
2FA setup

  • watchers can be added to forum threads (#3390)


Since version 4.2.1 has already been released, which is really a patch release that fixes the slight youth issues that version 4.2.0 might bring, I would recommend upgrading your Redmine installation to this latest version. In fact, I have already performed several upgrades, all of them without problems.


It is always advisable to make a first test migration and, once we have seen that this has occurred without incidents, then, perform the final migration. Although, as I said before, I do not foresee that major problems may arise when upgrading to this version, it is possible that, if you come from an older version, you have to be careful with the plugins you have installed. It is possible that old plugins and not updated by their developer are not compatible with this version of Redmine.


Best Redmine Themes Zenmine and Boostmine, are now compatible with the latest version of Redmine.
