I emailed support and asked things like this. Here were the responses that I was given:
Thanks for your email! Like many software companies (e.g. such as Atlassian/JIRA), we don’t publish our roadmap publicly, as we prefer not to overpromise and underdeliver. Our team at Gurock has actually more than doubled now in the last 12 months, and we only have plans to grow and add more features and functionality to TestRail. Business itself has grown tremendously over the past year and we’re working hard to staff up in all phases of the company (product management, development, marketing, and support), and we’re working to meet the demands of our customers. I can assure you that we are actively developing new features and making changes based on customer feedback, and we’ve actually been more actively engaged in reaching out to customers to receive feedback and make actionable decisions on how to best improve TestRail (someone on your team may have even received several emails regarding surveys recently).
I pressed a bit further on the lack of much in the last release and the slow cycles and I was given a bit more:
Thanks for your email! Yes, in the last year we’ve been focused on improving our TestRail Cloud infrastructure as well as adding more platform support for TestRail Server customers, with some smaller bug fixes and usability fixes. We’ve also been working to onboard our new team members and developers to adhere to the same quality and efficiency standards that our customers have come to expect. We’ll be posting a formal update soon regarding the new TestRail Cloud infrastructure changes that we’ve been working on in that regard. In regards to new features, while I can’t provide any specifics, you will start to see some new feature/changes to TestRail very early in the new year, and then a steady flow of getting back to full feature releases with multiple releases each year. Keep an eye on our blog, as that’s the fastest way to get updates when we post about this!
Not sure if that helps, but that is the update I got when I emailed.
