Today, a new development snapshot of the DCMTK has been made available. This is the second snapshot after the last official release. 
Basically, only minor issues have been fixed that were detected after the publication of the previous version. In addition, the toolkit has been adapted for the latest final text supplements and correction items, i.e. the data dictionary as well as the list of SOP classes and transfer syntaxes are again up-to-date.
Further details on what has changed can be found in the CHANGES file — as always. If you are interested in the differences on a source code level, check the web interface of our public git repository, which provides a nice colored “diff” feature.
