===============================


General
-------

* Possibility to restrict the allowed DICOM commands for each modality

Orthanc Explorer
----------------

* The first screen of Orthanc Explorer is now a form to do studies lookups
* Support of large databases, by limiting the results to 100 patients or studies

REST API
--------

* New URI: "/studies/.../merge" to merge a study
* New URI: "/studies/.../split" to split a study

Maintenance
-----------

* Executing a query/retrieve from the REST API now creates a job
* Fix: Closing DICOM associations after running query/retrieve from REST API

==========================

General
-------

----------------

* Query/retrieve: Added button for "DX" modality

REST API
--------

* "/tools/reconstruct" to reconstruct the main DICOM tags, the JSON summary and
  the metadata of all the instances stored in Orthanc. This is a slow operation!

Plugins
-------

* New primitives to access Orthanc peers from plugins
* New events in change callbacks: "UpdatedPeers" and "UpdatedModalities"
* New primitives to handle jobs from plugins: "OrthancPluginSubmitJob()"
  and "OrthancPluginRegisterJobsUnserializer()"
