OJS, OMP, and OPS 3.3 Release Candidates

December 10th, 2020 by  | Comments Off on OJS, OMP, and OPS 3.3 Release Candidates

PKP announces today that OJS/OMP/OPS 3.3 will be released in the first quarter of 2021 (January – March). Release candidates are now available for testing and a feature freeze is in effect until then to complete translations, documentation, and plugin development.

In preparation for 3.3, PKP invites OJS, OMP, and OPS users to test our release candidate packages. In order to participate, users must be able to install and test the release candidates on their own. We recommend users test upgrades, plugins, and integrations related to their installation. Environment testing (to make sure the new code is compatible with your hosting environment) and regression testing (looking for “broken” areas) will help us to ensure our release is compatible with a broad array of environments, languages, and workflows. A complete list of changes for 3.3 is available for review in GitHub (see also below for a sneak peek!). 

Please note that the following packages should only be used for testing purposes and are not supported outside of this use: 

Experienced and technical users are invited to submit bugs and feedback via GitHub. Please share any additional feedback on the PKP Community Forum.

Our thanks to all those able to test and share feedback, with special thanks to PKP Publishing Services staff and clients, PKP Development Partners, and PKP Technical Committee members for their ongoing contributions and support.


OJS/OMP/OPS 3.3 addresses several long-standing requests, many of which were shared by community members at PKP sprints. Following are a few of the upcoming changes that will impact how our software is used:

  • You’ll notice subtle but important changes to the look and feel of the editorial backend. We’ve refactored the user interface to improve accessibility.
  • We’ve simplified the submission process for authors with a new component that enables authors to upload multiple files at once, as well as drag-and-drop files.
  • If you’ve ever needed to identify submissions that are urgent, planned for a special issue, or locate submissions from published issues you’ll like our new submission filters to filter by assigned issue and editor.
  • Do you use Mailchimp or other third-party mailing services to contact users? 3.3 now supports user export in spreadsheet format (Excel/CSV).
  • Notify by role is back! You can now send an email to all users with a specific role.
