'go mod download' without arguments is frequently used to populate the module cache. It tends to fetch a lot of extra files (for modules in the build list that aren't needed to build packages in the main module). It's annoying when sums are written for these extra files. 'go mod download mod@version' will still write sums for specific modules in the build list. 'go mod download all' still has the previous behavior. For now, all invocations of 'go mod download' still update go.mod and go.sum with changes needed to load the build list (1.15 behavior).

As <a href="go1.16#darwin">announced</a> in the Go 1.16 release

<code>windows/arm64</code> port). This port supports cgo.

The 64-bit MIPS architecture on OpenBSD (the <code>openbsd/mips64</code>
|

port) now supports cgo.

|
<p><!-- golang.org/issue/36435 -->
|
|
In Go 1.16, on the 64-bit x86 and 64-bit ARM architectures on
|
|
OpenBSD (the <code>openbsd/amd64</code> and <code>openbsd/arm64</code>
|
|
ports) system calls are made through <code>libc</code>, instead
|
|
of directly using the machine instructions. In Go 1.17, this is
|
|
also done on the 32-bit x86 and 32-bit ARM architectures on OpenBSD
|
|
(the <code>openbsd/386</code> and <code>openbsd/arm</code> ports).
|
|
This ensures forward-compatibility with future versions of
|
|
OpenBSD.

<h4 id="lazy-loading">Lazy module loading</h4>
|
|
|
|
<p><!-- golang.org/issue/36460 -->
|
|
If a module specifies <code>go</code> <code>1.17</code> or higher in its
|
|
<code>go.mod</code> file, its transitive requirements are now loaded lazily,
|
|
avoiding the need to download or read <code>go.mod</code> files for
|
|
otherwise-irrelevant dependencies. To support lazy loading, in Go 1.17 modules
|
|
the <code>go</code> command maintains <em>explicit</em> requirements in
|
|
the <code>go.mod</code> file for every dependency that provides any package
|
|
transitively imported by any package or test within the module.
|
|
See <a href="https://golang.org/design/36460-lazy-module-loading">the design
|
|
document</a> for more detail.
|
|
<!-- TODO(bcmills): replace the design-doc link with proper documentation. -->
|
|
</p>
|
|
|
|
<p><!-- golang.org/issue/45094 --> To facilitate the upgrade to lazy loading,
|
|
the <code>go</code> <code>mod</code> <code>tidy</code> subcommand now supports
|
|
a <code>-go</code> flag to set or change the <code>go</code> version in
|
|
the <code>go.mod</code> file. To enable lazy loading for an existing module
|
|
without changing the selected versions of its dependencies, run:
|
|
</p>
|
|
|
|
<pre>
|
|
go mod tidy -go=1.17

<h4 id="module-deprecation-comments">Module deprecation comments</h4>
|
|
|
|
<p><!-- golang.org/issue/40357 -->
|
|
Module authors may deprecate a module by adding a
|
|
<a href="/ref/mod#go-mod-file-module-deprecation"><code>// Deprecated:</code>
|
|
comment</a> to <code>go.mod</code>, then tagging a new version.
|
|
<code>go</code> <code>get</code> now prints a warning if a module needed to
|
|
build packages named on the command line is deprecated. <code>go</code>
|
|
<code>list</code> <code>-m</code> <code>-u</code> prints deprecations for all
|
|
dependencies (use <code>-f</code> or <code>-json</code> to show the full
|
|
message). The <code>go</code> command considers different major versions to
|
|
be distinct modules, so this mechanism may be used, for example, to provide
|
|
users with migration instructions for a new major version.
|
|
</p>
|
|
|
|
<h4 id="go-get"><code>go</code> <code>get</code></h4>
|
|
|
|
<p><!-- golang.org/issue/37519 -->
|
|
The <code>go</code> <code>get</code> <code>-insecure</code> flag is
|
|
deprecated and has been removed. To permit the use of insecure schemes
|
|
when fetching dependencies, please use the <code>GOINSECURE</code>
|
|
environment variable. The <code>-insecure</code> flag also bypassed module
|
|
sum validation, use <code>GOPRIVATE</code> or <code>GONOSUMDB</code> if
|
|
you need that functionality. See <code>go</code> <code>help</code>
|
|
<code>environment</code> for details.

<h4 id="missing-go-directive"><code>go.mod</code> files missing <code>go</code> directives</h4>

If the main module's <code>go.mod</code> file does not contain
|

a <a href="/doc/modules/gomod-ref#go"><code>go</code> directive</a> and
|
|
the <code>go</code> command cannot update the <code>go.mod</code> file, the
|
|
<code>go</code> command now assumes <code>go 1.11</code> instead of the
|
|
current release. (<code>go</code> <code>mod</code> <code>init</code> has added
|
|
<code>go</code> directives automatically <a href="/doc/go1.12#modules">since
|
|
Go 1.12</a>.)

<p><!-- golang.org/issue/44976 -->

If a module dependency lacks an explicit <code>go.mod</code> file, or
|
|
its <code>go.mod</code> file does not contain
|
|
a <a href="/doc/modules/gomod-ref#go"><code>go</code> directive</a>,
|
|
the <code>go</code> command now assumes <code>go 1.16</code> for that
|
|
dependency instead of the current release. (Dependencies developed in GOPATH
|
|
mode may lack a <code>go.mod</code> file, and
|
|
the <code>vendor/modules.txt</code> has to date never recorded
|
|
the <code>go</code> versions indicated by dependencies' <code>go.mod</code>

files.)

<h4 id="vendor"><code>vendor</code> contents</h4>

<p><!-- golang.org/issue/36876 -->
|
|
If the main module specifies <code>go</code> <code>1.17</code> or higher,
|
|
<code>go</code> <code>mod</code> <code>vendor</code> now annotates
|
|
<code>vendor/modules.txt</code> with the <code>go</code> version indicated by
|
|
each vendored module in its own <code>go.mod</code> file. The annotated
|
|
version is used when building the module's packages from vendored source code.
|
|
</p>
|
|
|
|
<p><!-- golang.org/issue/42970 -->
|
|
If the main module specifies <code>go</code> <code>1.17</code> or higher,
|
|
<code>go</code> <code>mod</code> <code>vendor</code> now omits <code>go.mod</code>
|
|
and <code>go.sum</code> files for vendored dependencies, which can otherwise
|
|
interfere with the ability of the <code>go</code> command to identify the correct
|
|
module root when invoked within the <code>vendor</code> tree.

|
<h4 id="password-prompts">Password prompts</h4>
|
|
|
|
<p><!-- golang.org/issue/44904 -->
|
|
The <code>go</code> command by default now suppresses SSH password prompts and
|
|
Git Credential Manager prompts when fetching Git repositories using SSH, as it
|
|
already did previously for other Git password prompts. Users authenticating to
|
|
private Git repos with password-protected SSH may configure
|
|
an <code>ssh-agent</code> to enable the <code>go</code> command to use
|
|
password-protected SSH keys.

<h4 id="go-mod-download"><code>go</code> <code>mod</code> <code>download</code></h4>
|
|
|
|
<p><!-- golang.org/issue/45332 -->
|
|
When <code>go</code> <code>mod</code> <code>download</code> is invoked without
|
|
arguments, it will no longer save sums for downloaded module content to
|
|
<code>go.sum</code>. It may still make changes to <code>go.mod</code> and
|
|
<code>go.sum</code> needed to load the build list. This is the same as the
|
|
behavior in Go 1.15. To save sums for all modules, use <code>go</code>
|
|
<code>mod</code> <code>download</code> <code>all</code>.
