squash

In simple English

In software development, squash has two primary meanings. First, it refers to a Git operation where you merge multiple commits into one, creating a cleaner commit history. This is commonly done before merging a feature branch into main. Second, it means to fix or eliminate bugs and issues rapidly, often used urgently when problems are discovered close to deployment. For example, a developer might say we need to squash these bugs before launch, meaning we must fix them quickly and completely. The term carries a sense of urgency and decisiveness in both contexts.

Handle with care. Do not confuse with the vegetable. In tech, squash always refers to combining commits or fixing bugs, never to physical compression or the sport.

We squashed the entire feature.
We squashed the bugs in the feature.You squash specific issues or commits, not entire features. Be precise about what you are squashing.
