As Tendo says, and Daniel says earlier on the thread, we always recommend our latest stable release.
Typically you would find more installations running older versions versus a just-released version, but you should start from a newer version anyway, because otherwise you’re just setting yourself up for needing to do an expensive upgrade sooner.
Also, to the big picture question of “What OpenMRS to use” you should consider broadly:
- the OpenMRS Platform (which would be the basis of an EMR application, which you’d completely build on top of that)
- one of the OpenMRS Distributions of which the two general purpose ones are the Reference Application, and Bahmni.
@brightoibe, I know that you have a larger list of questions to go with this one. Would you mind posting those as a new topic in the #dev category?
