This issue is about improving how the information in the Software Name and Software Version fields are mapped to DataCite properties in the OpenAIRE export.
Dataverse's Software Name and Software Version fields, in the Citation metadata block, are mapped to DataCite's description property with descriptionType "Methods".

<descriptions>
<description descriptionType="Methods">SPSS, 11</description>

DataCite 4 added a descriptionType called TechnicalInfo that seems more appropriate:
For software description, this may include a readme.txt, and necessary environmental information such as hardware, operational software, applications/programs, and versions. For other uses, this can include specific and detailed information as necessary and appropriate.
