Version information

Version 1.21.0•for Jira Data Center 7.6.0 - 11.3.10

Release date: Aug 13th 2026
Summary: Performance improvements, bug fixes, and incremental migration enhancements
Details: This release improves the reliability and performance of project migrations. Scoped user extraction is now more accurate: user and group references found through cross-project data and Assets are no longer silently dropped during sequential extraction. The group-picker change history query now scans large tables once instead of twice, preventing connection timeouts on large projects. Dry-run migrations now correctly include Assets data upload, matching the full migration behaviour. Transient database errors during comment reading are now automatically retried, reducing failures from temporary connectivity issues. Incremental cloud-hosted CMA migrations now support delta export of custom field options and object entities, exporting only changed items. A safeguard has been added to prevent cross-project data import from starting if a project migration step fails. Migration analytics events now include reconciliation identifiers, improving observability of migration runs.
