Some new features just got released 
Improved Linear integration: You can now create, search for, and link issues in Linear as requirements or defects directly from Testiny. Additionally, the current status of linked issues is displayed in Testiny.
Testiny Server: We released a Jira Data Center Add-on that provides the same features as the Testiny Jira Cloud Add-on (overview on all Testiny test cases, test runs, and executions linked to an issue).
See all features and bug fixes in our changelog .
Note: There is no automatic migration from the previous link-based Linear integration to the new full two-way integration. However, you can use both integrations side-by-side.
