TestRail 10.0.1.1010 Server

Default release track date: 17-Feb-2026

We’re excited to announce the release of TestRail 10.0.1, introducing Jira Issue Connect, our new real-time Jira integration experience, along with a platform upgrade to PHP 8.3 and a series of fixes and improvements to keep your QA workflows reliable and scalable.

This release also introduces backend optimizations that significantly improve the performance of dashboard queries, resulting in faster loading times and a more responsive experience for projects with larger datasets.

Jira Issue Connect 

TestRail 10.0 introduces Jira Issue Connect, a real-time, two-way Jira Cloud integration that brings Jira requirements and defects directly into TestRail.

No tab-switching. No duplicate data. No manual status chasing.
Just live Jira context, available everywhere testing happens, including test cases, runs, and reports.

With Jira Issue Connect, you can:

• Work with live Jira fields inside TestRail: View Jira status, assignee, and fix version directly alongside linked References and Defects.
• Keep traceability intact end-to-end: Connect Jira requirements, tests, results, and defects in a single workflow.
• Configure what gets synced: Select which Jira projects and fields to connect for References and Defects, keeping workflows tailored and focused.
• Create consistent defects with predefined defaults: Apply default Jira field values to reduce manual rework and improve consistency.
• Bring Jira context into TestRail reporting: Jira data flows into reports, unlocking References and Defects coverage tracking for the first time.

⚙️ Platform Upgrade: PHP 8.3

TestRail 10.0 also includes an upgrade to PHP 8.3, strengthening platform security, performance, and long-term maintainability.

This update helps ensure TestRail remains stable and future-ready as we continue to expand core capabilities and integrations.

💻 TestRail CLI 1.12.6

The latest version of the TestRail CLI is now available with new capabilities:

• You can now allow parse_junit to update custom case fields in the same test run when using --update-existing-cases.
