March 14, 2015 - HAPI FHIR 0.9 Released - HAPI 0.9 has now been released (both as binaries you can download from GitHub and as Maven dependencies you can download from Maven central). This release is an important one. It brings a number of fixes and new features, and most importantly brings suport for DSTU2 resources and parsing/encoding. DSTU2 is the upcoming next version of the FHIR specification itself. Also of particular note, the JPA Server has graduated to being included in the Maven repos (so you can create your own server which works just like ours). The Android JAR has also been included.
As always, you can see the complete list of what has changed by consulting the changelog, and the download page has information on where to get it.
Note on DSTU2: It is important to note that DSTU2 is not yet formally ballotted by HL7, and as such it is subject to change. A number of developers are starting to target it however, so support was important to us at HAPI HQ. See the HAPI DSTU2 page for information about how to add support for FHIR DSTU2 in your applications.
What's Next: We are planning on making the next release of HAPI be the 1.0 release. The biggest development on our plate for the next development cycle will be to finish the integration of the HL7.org structure classes. Some people may have noticed a project in our GitHub repo called "hapi-fhir-structures-hl7org" that isn't a part of the current build. What we are trying to do is to unify the HL7.org Java Reference Implementation data model with the HAPI one in a single set of classes. This will mean that HAPI users can take advantage of tools from the RI (such as the excellent validator that comes with it) and users of the RI can take advantage of HAPI's client and server toolkits. It is still not 100% clear what this integration will look like when it is complete, but that should become clear in the coming weeks.
As always, thanks to everyone who contributed code, pull requests, and filed bugs to make this release better. HAPI FHIR is the collective work of a large number of people now and we all benefit from the collective hard work being put in from around the world!
