I have a Mantis bug tracker installed that we use for all of our products. One product goes through a rapid development cycle and each new build gets a new version number (the build number is incremented). Since our QA has to report all bugs they found for the build that introduced the bug, we also have to add a new version number to Mantis every time a new build is made. Because of this, the list of version numbers under Manage->Manage Projects->Project name is now very long.
I just tried to delete one of the very old version numbers but that removes that number from all issues that referred to it. (Makes sense from a DB design point-of-view.)
Is there a way to shorten the version list without affecting the issues? The very old version number we have will never be used again but I want the old issues intact. I did a bunch of Google searches but I keep getting flooded with unrelated results.
If I understand you properly, what you'd like is a way to filter the versions displayed in the Manage Projects page.
This cannot be done in current version of MantisBT (1.2.14), and would require a change in the code. I suggest you open a feature request on our tracker. If you end up implementing the feature, then submit it as a pull request on our Github repository.
