# Hotfix - JMWE for Jira Data Center 9.1.1

**Release date**: December 6, 2024


# Hotfix

### Fix for ‘Set Issue Fields’ post function

Atlassian recently upgraded its JSON serialization library for Jira 10. The update for JMWE for Jira Data Center inadvertently caused existing Set Issue Fields post functions to stop working on Jira 9 installations. This issue did not affect post functions created after the JMWE 9.1 update. 

This hotfix restores full functionality to existing post functions.
