 Identifying whether a Go binary or toolset is from the Microsoft build of Go or the official Go distribution can be important for diagnostics and verifying expectations.
 
 As of Go 1.25, `go version` and `go version -m` don't clearly indicate the source of the toolset or binary.
-We plan to address this: see [microsoft/go#262](https://github.com/microsoft/go/issues/262).
-In the meantime, this document describes how to identify a Go program or Go toolset.
+
+As of Go 1.26, setting `GODEBUG=ms_version=1` makes `go version` report the Microsoft build version string.
+`go version -m <program>` on a `program` built by the Microsoft build of Go always includes a `microsoft_toolset_version` line specifying the Microsoft version.
+
+> [!TIP]
+> If you always set `GODEBUG=ms_version=1`, you will always have the most reliable information available.
+> If the toolset doesn't support this setting, it will simply be ignored.
+
+The below sections provide step-by-step processes to help identify a Microsoft build of Go toolset and binaries built by it.
 
 ## Identifying a Go toolset

 `systemcrypto` is unique to the Microsoft build of Go, so if either of these strings is present, it confirms that the binary is built by the Microsoft build of Go.
 
-If `GOEXPERIMENT=nosystemcrypto` is present (note the `no` prefix), it confirms that the binary was built with the Microsoft build of Go, but `systemcrypto` was explicitly disabled.
+If `GOEXPERIMENT=nosystemcrypto` is present (note the `no` prefix), it also confirms that the binary was built with the Microsoft build of Go, but it shows that `systemcrypto` was explicitly disabled.
 
 If none of the above are present, we can't confirm which build of Go was used.
 However, this situation means that the application doesn't meet Microsoft internal crypto policy, which may be enough information in some cases.
