We are changing our policy with respect to HPO releases. This will affect both, the ontology data, as well as the annotation files. Previously, every edit that was made, resulted in a ‘release’.
Now every edit is checked for consistency (using Travis), but we will only create a new release on our Hudson/Jenkins server in larger, but regular, intervals. We aim at releases about once or twice a month.
Note, that all of this will change again in the near future, when we will be switching to github-releases.
For all users that use the PURLs for accessing the ontology data this will not be a problem (http://purl.obolibrary.org/obo/hp.obo and http://purl.obolibrary.org/obo/hp.owl).
Please contact me if you have any questions (email@example.com).
