Second round of improvements in 2.x series This release brings two major improvements. First there is the much better integration of changelogs into the Hawat web interface components, which enables administrators better monitoring of user changes. The other major improvement is the grunt work for implementing API interface has been done and the event search form is the first part of the interface that provides the JSON API. To enable access to the API from arbitrary scripts and applications a new authentication mechanism based on API keys was implemented.
