<code>go</code> <code>get</code> no longer builds or installs packages in
|
|
module-aware mode. <code>go</code> <code>get</code> is now dedicated to
|
|
adjusting dependencies in <code>go.mod</code>. Effectively, the
|
|
<code>-d</code> flag is always enabled. To install the latest version
|
|
of an executable outside the context of the current module, use
|
|
<a href="https://golang.org/ref/mod#go-install"><code>go</code>
|
|
<code>install</code> <code>example.com/cmd@latest</code></a>. Any
|
|
<a href="https://golang.org/ref/mod#version-queries">version query</a>
|
|
may be used instead of <code>latest</code>. This form of <code>go</code>
|
|
<code>install</code> was added in Go 1.16, so projects supporting older
|
|
versions may need to provide install instructions for both <code>go</code>
|
|
<code>install</code> and <code>go</code> <code>get</code>. <code>go</code>
|
|
<code>get</code> now reports an error when used outside a module, since there
|
|
is no <code>go.mod</code> file to update. In GOPATH mode (with
|
|
<code>GO111MODULE=off</code>), <code>go</code> <code>get</code> still builds
|
|
and installs packages, as before.

<code>gofmt</code> now reads and formats input files concurrently, with a

|
memory limit proportional to <code>GOMAXPROCS</code>. On a machine with
|
|
multiple CPUs, gofmt should now be significantly faster.

The <code>Draw</code> and <code>DrawMask</code> fallback implementations
|
|
(used when the arguments are not the most common image types) are now
|
|
faster when those arguments implement the optional
|
|
<a href="/pkg/image/draw/#RGBA64Image"><code>draw.RGBA64Image</code></a>
|
|
and <a href="/pkg/image/#RGBA64Image"><code>image.RGBA64Image</code></a>

|
interfaces that were added in Go 1.17.

The new function <a href="/pkg/syscall/?GOOS=windows#SyscallN"><code>SyscallN</code></a>
|
|
has been introduced for Windows, allowing for calls with arbitrary number
|

of arguments. As results,
|

<a href="/pkg/syscall/?GOOS=windows#Syscall6"><code>Syscall6</code></a>,

<a href="/pkg/syscall/?GOOS=windows#Syscall15"><code>Syscall15</code></a>, and

<a href="/pkg/syscall/?GOOS=windows#Syscall18"><code>Syscall18</code></a> are

deprecated in favor of <a href="/pkg/syscall/?GOOS=windows#SyscallN"><code>SyscallN</code></a>.
