How do I catch a regression in my game?

Catch a regression by tracking stability per version, comparing each release against the previous one, and alerting on new or increased crashes so it surfaces immediately. Step one, track per version: record crashes and issues tagged with the version they occurred in, so each release has a stability profile, you cannot tell an update broke something without knowing which version each crash came from. Step two, compare releases: look for crashes that are new in a version (did not exist before) or that increased (a signature occurring more often), since a new or increased crash in a release is the signature of a regression. Step three, alert immediately: set up alerts on a new crash spiking on a release, so a regression surfaces the moment an update breaks something, letting you fix or roll back before it spreads. A regression is something an update broke that worked before, so per-version comparison is the key. Bugnet provides all three: it tags every crash with the version (per-version tracking), shows which crash signatures are new or increased in a release (comparison), and alerts when a new crash spikes (immediate detection), so you catch regressions the moment they ship, which is how you catch a regression in your game.

What is a regression in game development?

A regression in game development is when a change (usually an update) breaks something that previously worked, reintroducing a bug, breaking a feature, or degrading stability or performance that was fine before. The defining feature is that it is new breakage caused by a change: something was working, you shipped an update, and now it is broken, the update regressed it. Regressions are common because changes can have unintended side effects, touching code (or assets, or configuration) that affects something seemingly unrelated, or reintroducing a previously-fixed bug. They are dangerous because they can ship unnoticed (you tested the new feature, not the thing that broke) and reach players, turning an update meant to improve the game into one that harms it. Catching regressions requires being able to tell that a release introduced new problems, which means tracking stability per version and comparing releases. Bugnet enables that: it tracks crashes per version, so you can see which crash signatures are new or increased in a release compared to the previous version, the signature of a regression, with alerts when one spikes, so you catch regressions an update introduced, which is what a regression is and how to detect it.

How do I know if an update broke something?

Know if an update broke something by comparing the update's stability against the previous version, watching for crashes that are new or increased after the release, with alerts so you find out immediately. An update breaks something when it introduces a regression, a new crash, a reintroduced bug, degraded performance, that was not there before, so the way to detect it is to compare the new version against the prior one: are there crash signatures occurring in this version that did not occur before, or signatures occurring more frequently? Either indicates the update broke something. The challenge is that the breakage may be in an area you did not test (you tested the new feature, not the unrelated thing that broke), so you cannot rely on noticing it yourself, you need data that surfaces new problems automatically. This requires per-version stability tracking and ideally alerts, so a regression surfaces immediately rather than after players have been hitting it for days. Bugnet provides it: it tracks crashes per version and shows which signatures are new or increased in a release, with real-time alerts when a new crash spikes, so you know within minutes if an update broke something and can respond, which is how you know if an update broke something.

Steps to Catch a Regression

Quick answer: To catch a regression: track stability per version, compare each release against the previous, and alert on new or increased crashes so a regression surfaces immediately.

A regression is when an update breaks something that worked. These are the steps to catch one fast.

Step 1: Track Stability Per Version

Start by tracking your game's stability per version: record crashes and issues tagged with the version they occurred in, so each release has a stability profile. Per-version tracking is the foundation of catching regressions, you cannot tell an update broke something without knowing which version each crash came from.

Bugnet tracks everything per version automatically: every crash is tagged with the game version, so each release has a stability record, giving you the per-version data that makes regression detection possible rather than having crashes in an undifferentiated pile.

Step 2: Compare Each Release Against the Previous

Next, compare each new release against the previous one: look for crashes that are new in this version (did not exist before) or that increased (a signature occurring more often). A new or increased crash in a release is the signature of a regression, something the update broke.

Bugnet makes the comparison clear: it shows crashes per version, so you can see which crash signatures are new in a release or have increased compared to the previous version, surfacing the regressions an update introduced rather than leaving you to spot them in aggregate data.

Step 3: Alert So Regressions Surface Immediately

Finally, set up alerts so a regression surfaces immediately rather than after it spreads: an alert on a new crash spiking on a release tells you the moment an update has broken something, so you can fix or roll back fast. Immediate alerting is what lets you catch a regression while the damage is small.

Bugnet provides the alerts: it notifies you when a new crash spikes on a release, so a regression an update introduced surfaces within minutes of the release going out, letting you respond before it spreads across your player base, catching the regression at the earliest possible moment.

To catch a regression: track stability per version, compare each release against the previous, and alert on new or increased crashes so it surfaces immediately, per-version comparison is how you catch what an update broke before it spreads.
