https://github.com/golang/go/wiki/Go-Release-Cycle
go1.26 arrives six months after Go 1.25. Most of its changes are
in the implementation of the toolchain, runtime, and
libraries. As always, the release maintains the Go 1 promise of
compatibility. We expect almost all Go programs to continue to
compile and run as before.
- Language change: The built-in new function, which creates a new
variable, now allows its operand to be an expression,
specifying the initial value of the variable.
- Language change: The restriction that a generic type may not
refer to itself in its type parameter list has been lifted. It
is now possible to specify type constraints that refer to the
generic type being constrained.
- go command: The venerable go fix command has been completely
revamped and is now the home of Go's modernizers. It provides a
dependable, push-button way to update Go code bases to the
latest idioms and core library APIs. The initial suite of
modernizers includes dozens of fixers to make use of modern
features of the Go language and library, as well a source-level
inliner that allows users to automate their own API migrations
using //go:fix inline directives. These fixers should not
change the behavior of your program, so if you encounter any
issues with a fix performed by go fix, please report it.
- go command: The rewritten go fix command builds atop the exact
same Go analysis framework as go vet. This means the same
analyzers that provide diagnostics in go vet can be used to
suggest and apply fixes in go fix. The go fix command's
historical fixers, all of which were obsolete, have been
removed.
- go command: Two upcoming Go blog posts will go into more detail
on modernizers, the inliner, and how to get the most out of go
fix.
- go command: go mod init now defaults to a lower go version in
new go.mod files. Running go mod init using a toolchain of
version 1.N.X will create a go.mod file specifying the Go
version go 1.(N-1).0. Pre-release versions of 1.N will create
go.mod files specifyi
