+ This change breaks backwards compatibility in small ways, some obvious—patterns with "{" and "}" behave differently—
and some less so—treatment of escaped paths has been improved.
The change is controlled by a <a href="/doc/godebug"><code>GODEBUG</code></a> field named <code>httpmuxgo121</code>.
Set <code>httpmuxgo121=1</code> to restore the old behavior.
<p><!-- https://go.dev/issue/60797 -->
The <code>syscall</code> package has been <a href="https://golang.org/s/go1.4-syscall">frozen</a> since Go 1.4 and was marked as deprecated in Go 1.11, causing many editors to warn about any use of the package.
However, some non-deprecated functionality requires use of the <code>syscall</code> package, such as the <a href="/pkg/os/exec#Cmd"><code>os/exec.Cmd.SysProcAttr</code></a> field.
- To avoid unnecesary complaints on such code, the <code>syscall</code> package is no longer marked as deprecated.
+ To avoid unnecessary complaints on such code, the <code>syscall</code> package is no longer marked as deprecated.
The package remains frozen to most new functionality, and new code remains encouraged to use <a href="/pkg/golang.org/x/sys/unix"><code>golang.org/x/sys/unix</code></a> or <a href="/pkg/golang.org/x/sys/windows"><code>golang.org/x/sys/windows</code></a> where possible.
