| ## Tools {#tools} |
| |
| <!-- go.dev/issue/77177 --> |
| |
| Response file (`@file`) parsing is now supported for the `compile`, `link`, `asm`, `cgo`, `cover`, and `pack` tools. |
| The response file contains whitespace-separated arguments with support for single-quoted and double-quoted strings, escape sequences, and backslash-newline line continuation. |
| The format is compatible with GCC's response file implementation to ensure interoperability with existing build systems. |
| |
| ### Go command {#go-command} |
| |
| `go test` now invokes the stdversion vet check by default. |
| This reports the use of standard library symbols that are too new |
| for the Go version in force in the referring file, |
| as determined by `go` directive in `go.mod` and build tags on the file. |
| |
| <!-- go.dev/issue/78090 --> |
| |
| The `go` command no longer has support for the bzr version control system. |
| It will no longer be able to directly fetch modules hosted on bzr servers. |
| |
| ### Cgo {#cgo} |
| |
| ### Trace |
| |
| <!-- go.dev/issue/78921 --> |
| |
| `go tool trace`'s `-http` argument now restricts the listen address to localhost when passed only a port (e.g., `-http=:6060`). |
| This change makes `go tool trace` consistent with the behavior of `go tool pprof`'s `-http` flag. |
| To listen on all addresses, explicitly include the specified address (e.g., `-http=0.0.0.0:6060`). |
