Crackling crust, pillowy middle. The kind of bagel that earns a second cup of coffee.
Summary
The Go programming language team announces experimental support for new JSON packages (encoding/json/jsontext and encoding/json/v2) in Go 1.25, marking the first major overhaul of JSON handling in Go since the original encoding/json package was introduced nearly 15 years ago. The new APIs address long-standing limitations of the original package, including better performance, more flexible marshaling/unmarshaling, improved handling of streaming JSON, and a redesigned interface that better fits modern Go idioms. The article details the motivation behind the redesign, the new API design principles, and provides examples of how developers can use the new packages.
