Quick answer: To fix a regression: identify what broke and which release introduced it, find the change that caused it, fix it or revert that change, and verify the regression is resolved.
A regression is something an update broke that worked before. These are the steps to fix one.
Step 1: Identify What Broke and Which Release Introduced It
Start by identifying what broke and which release introduced it: a regression is new breakage from a change, so pinpointing the release where the problem started narrows the cause to the changes in that release. Knowing the introducing version is the key first step to fixing a regression efficiently.
Bugnet identifies the introducing release: by tracking crashes per version, it shows you which version a crash first appeared or spiked in, so you immediately know which release introduced the regression, narrowing the cause to that release's changes rather than searching your whole history.
Step 2: Find the Change That Caused It
Next, find the specific change in that release that caused the regression: review what changed in the introducing version and identify the change responsible, using the crash context (where it fails, the conditions) to connect the breakage to the change. This pinpoints what to fix or revert.
Bugnet helps connect breakage to change: the stack trace and context show where and how the regression fails, and knowing it started in a specific release narrows it to that release's changes, so you can identify the responsible change rather than guessing across everything you have ever done.
Step 3: Fix or Revert, Then Verify
Finally, fix the responsible change (or revert it if reverting is safer and the change is not essential), then verify the regression is resolved, the crash stops in the version with the fix. Because a regression is something that worked before, verifying it is restored confirms you genuinely fixed it.
Bugnet verifies per version: after your fix or revert, it shows whether the regression's crash stops occurring in the new version, so you confirm the regression is genuinely resolved on real player data, and per-version tracking catches it if it ever returns, closing out the regression with verification.
To fix a regression: identify what broke and which release introduced it, find the change that caused it, fix or revert that change, and verify the regression is resolved, identifying the introducing release and change is the key to fixing it efficiently.
