### Go command {#go-command}

### Cgo {#cgo}

Cgo currently refuses to compile calls to a C function which has multiple
incompatible declarations. For instance, if `f` is declared as both `void f(int)`
and `void f(double)`, cgo will report an error instead of possibly generating an
incorrect call sequence for `f(0)`. New in this release is a better detector for
this error condition when the incompatible declarations appear in different
files. See [#67699](https://go.dev/issue/67699).
doc: initialize next directory for Go 1.24 Following the "For the release team" steps in README: cd doc cp -R initial/ next $EDITOR next/1-intro.md Dropped '*' from the cp -R command to avoid needing to create an empty next directory with a separate command. For #68545. For #67586.

cmd/cgo: error on multiple incompatible function declarations When there are multiple declarations of a function, ensure that those declarations at least agree on the size/alignment of arguments and return values. It's hard to be stricter given existing code and situations where arguments differ only by typedefs. For instance: int usleep(unsigned); int usleep(useconds_t); Fixes #67699.
