Summary: O3 recently had a major release to the underlying technology that:
- (A) resolves the vast majority of known performance issues in O3; and,
- (B) significantly reduces the exposed complexity of the O3 framework.
The release contains some breaking changes for O3 implementers. We know this can be intimidating - here are some resources to help folks with this process.
We do strongly recommend that O3 implementers upgrade to this version of the O3 Framework, specifically, esm-core-v5.1.x. If you haven’t already migrated to esm-core-v5.0, we advise you migrate directly to v5.1 (esm-core-v5.0 had some bugs in the patient chart that v5.1 fixes, so we want to save you those headaches).
Support with the O3-Core Migration
If your organization would like support with this upgrade, we recommend these 2 steps:
-
Must-Read Migration Guide: Have your technical team review this Migration Guide written for exactly this scenario! Migrating to Core v5 – O3 Docs
Optional Additional Video: Walkthrough by engineers explaining the current state of the foundational technology, and the abstractions that we have hidden to reduce complexity for feature developers: O3 App Shell Deep-Dive Recording
-
Daily O3 Dev Support Hours: Have relevant engineering members from your team join any of the O3 Dev “Coffee Chat” calls (like office hours for O3 developers) for 1:1 support from the OpenMRS Global Product Support Team. These are every Monday-to-Thursday at 2:30pm EAT / 5:00pm IST / 7:30am EDT on Zoom at https://om.rs/o3coffee - See it on the OpenMRS community calendar at https://om.rs/cal
And, if you have even more detailed questions or want a 1:1 session, please reach out to our Community’s Frontend Engineering Lead @dennis. We know this breaking change is intimidating for some teams and he’s very happy to help!

The OpenMRS 3 RefApp will soon be updated to include v5.1.x, (as part of the 3.0.0-beta.10 release, planned for this week) so then you will be able to also grab the updated docker image here: https://hub.docker.com/r/openmrs/openmrs-reference-application-3-frontend
Kudos
A huge thank you to @ibacher and @dennis who spent many painfully long hours in the last 2 months working on this very difficult release. Thanks also to SingleSPA founder and maintainer @joeldenning who helped us check through our work so we could benefit from lessons from the wider SingleSPA community and pro-actively check for any unintended future consequences. Thanks @raff for also tackling backend and API-related issues during this process. Thanks to the teams at @PalladiumKenya, @PIH, and @UCSF for being some of the first guinea-pigs to try out esm-core-v5.0 and share with us the issues you ran into. And thanks to our QA Support Team with @jayasanka and @piumal1999 and @anjisvj for the work they’re doing to firm-up our release pipeline - we are currently in the process of updating the automated smoke-tests that run against O3 PRs to adapt them after these breaking changes. Thanks team!!!
