- Size-specialized memory allocation reduces small object costs by up to 30%.
- The goroutineleak profile is now generally available for detecting blocked goroutines.
- `go mod tidy` now consolidates multiple `require` blocks in the `go.mod` file into a standard two-block structure.
- New modernizers have been added to the `go fix` tool, including `atomictypes` and `embedlit`.
