Quick answer: Yes, it's one of the most useful things you can know. Tying a bug to the version that introduced it tells you what changed, narrows the cause, and lets you fix or roll back fast. Without version tracking, every regression is a blind search.
Knowing which update introduced a bug, attributing a regression to a specific version, is enormously valuable for diagnosis. Do you need to track it? Yes, because it transforms debugging a regression from a blind search into a targeted investigation, and it's nearly free to capture.
It Tells You What Changed
When a bug starts appearing, the single most useful clue is when, specifically, which version it began in. That tells you exactly what changed to cause it: the diff between the last good version and the first bad one contains your culprit. Without that, you're searching your entire codebase blindly.
Bugnet tags every crash and report by version, so a new issue is automatically tied to the build it appeared in. Knowing the introducing version narrows your investigation from "somewhere in the game" to "in these specific changes."
It Speeds Fixes and Enables Rollback
Version attribution doesn't just help diagnosis, it enables fast response. Knowing an update broke something lets you decide quickly: fix forward in the changed code you can now pinpoint, or roll back to the known-good previous version. Both options depend on knowing which update is responsible.
Bugnet's per-version tracking gives you that attribution immediately, so you can act, fix or revert, without first spending hours figuring out which release caused the problem. The faster you know what broke it, the faster you resolve it.
It's Nearly Free to Capture
The clincher: tracking which update broke something costs almost nothing. The version is trivially captured with every report, and once you have it, regression attribution comes for free. There's no reason not to capture it, and every regression you'll ever debug is easier because you did.
Bugnet captures the version automatically with every crash and report, so you always know which build an issue appeared in. So yes, you need to track which update broke something, it's among the most useful diagnostic facts you can have, it speeds fixes and rollbacks, and it's effectively free to capture.
Yes, knowing which update introduced a bug tells you what changed, speeds the fix, and enables rollback. Without version tracking, every regression is a blind search. It's nearly free.
