As far as I can tell, there is no public documentation on this topic,
which cost me several days of debugging.
I am possibly unusual in that I run binaries in production with the
race detector turned on, but I think that others who do the same may

HTML pages served by the website have the option to opt-in to template
processing, by including "Template: true" in the page metadata.
This functionality is documented at
403f1254bd/godoc/template.go (L5-L30).
Historically, the Go 1 release notes have used template processing
to a great extent, but release notes for all subsequent major Go
releases have not.
Since this feature is generally not used and not very well known,
it tends to do more harm than good by making it possible for errors
in the template to prevent the release notes from showing up at all.
Disable this feature for Go 1.14 release notes and onwards.
We can consider enabling it when there's a stronger need for it.

In CL 199417, we updated “How to Write Go Code” to give a basic
introduction to modules and to include module-mode commands.
However, most new users will end up reading “Getting Started”
(doc/install.html) before “How to Write Go Code”, and we forgot to
update the handful of commands there for module mode.
Before this change, the “Test your installation” section also covered
quite a few operations beoyond merely testing the installation: it
included setting up a GOPATH, building a binary, and installing and
cleaning binaries. Those are valuable operations to learn, but they
arguably belong in “How to Write Go Code”, not “Test your
installation” — and having all that extra detail in the install
instructions may well discourage folks from further essential reading.
Rather than updating all of those operations here, I've removed them.
A companion CL will update “How to Write Go Code” to ensure that it
mentions GOPATH (as the location of the module cache and the default
install location for binaries) and 'go clean -i'.

The public proxy and checksum database launched with Go 1.13 have been
running smoothly, pkg.go.dev is serving module-aware documentation,
and in 1.14 we have improved the vendoring workflow and finished
Subversion support to reach parity with GOPATH mode for users of those
features, updated documentation (including the “How to Write Go Code”
intro document) and published blog posts describing common modes of
usage, and improved the migration path for existing v2+ modules by
making version resolution less aggressive about "+incompatible" major
versions.
We (always) have more fit-and-finish work to do, but at this point we
believe that module mode will provide a better user experience than
GOPATH mode for most users, including in production use.

After golang.org/cl/210124, I wondered if the same error had gone
unnoticed elsewhere. I quickly spotted another dozen mistakes after
reading through the output of:
git grep '\<[Aa]n [bcdfgjklmnpqrtvwyz][a-z]'
Many results are false positives for acronyms like "an mtime", since
it's pronounced "an em-time". However, the total amount of output isn't
that large given how simple the grep pattern is.

Not all closed issues in a given minor milestone are included in that
release, only the ones that have been labeled as CherryPickApproved are.
Update the links to the GitHub issue tracker to include a filter on the
CherryPickApproved label, so that the default view shows only the
backports that were included in a given release. This should more useful
to most people than seeing all backports (considered and approved).
Do this only for Go 1.9.1 and newer releases, as that is when we started
using the CherryPickCandidate and CherryPickApproved labels.

Previously we would always “upgrade” to the semantically-highest
version, even if a newer compatible version exists.
That made certain classes of mistakes irreversible: in general we
expect users to address bad releases by releasing a new (higher)
version, but if the bad release was an unintended +incompatible
version, then no release that includes a go.mod file can ever have a
higher version, and the bad release will be treated as “latest”
forever.
Instead, when considering a +incompatible version we now consult the
latest compatible (v0 or v1) release first. If the compatible release
contains a go.mod file, we ignore the +incompatible releases unless
they are expicitly requested (by version, commit ID, or branch name).

This change updates the GOARCH/GOOS discussion at the top of the
"Installing Go from source" document to better reflect the current
status. In particular:
- The GOARCH list now focuses on simply listing the supported
architectures, with no notes about their supposed "maturity", since
the same GOARCH can be mature on a GOOS and not so mature on another.
- Outdated notes about some archs being new and "not well-exercised"
have been removed in favour of a following list of which ports are
first class.
- The list of supported OS has been updated (added: AIX, Illumos),
and sorted in alphabetical order.
- A note about the runtime support being the same for all ARCHS,
"including garbage collection and efficient array slicing and" etc etc
has been removed, since it doesn't seem particularly relevant in a
"install from source" instruction page, and it's likely a leftover
from the time this doc page was the landing place for new people and
it felt the need to "sell" Go.

'GOFLAGS=-mod=vendor' currently causes 'go get' to always fail unless

we plan to set -mod=vendor by default if a vendor directory is
present, so all users with vendor directories will be affected — not
just those who set 'GOFLAGS' explicitly.
Similarly, an explicit '-mod=readonly' argument to 'go get' is
currently ignored as a special case, but the fact that it is ignored
(rather than rejected) can be very surprising.
Rather than adding more special cases, we should remove the '-mod'
flag from 'go get' entirely.

Previously, most operations involving pseudo-versions allowed any
arbitrary combination of version string and date, and would resolve to
the underlying revision (typically a Git commit hash) as long as that
revision existed.
There are a number of problems with that approach:
• The pseudo-version participates in minimal version selection. If its
version prefix is inaccurate, the pseudo-version may appear to have
higher precedence that the releases that follow it, effectively
“pinning” the module to that commit. For release tags, module
authors are the ones who make the decision about release tagging;
they should also have control over the pseudo-version precedence
within their module.
• The commit date within the pseudo-version provides a total order
among pseudo-versions. If it is not accurate, the pseudo-version
will sort into the wrong place relative to other commits with the
same version prefix.
To address those problems, this change restricts the pseudo-versions
that the 'go' command accepts, rendering some previously
accepted-but-not-canonical versions invalid. A pseudo-version is now
valid only if all of:
1. The tag from which the pseudo-version derives points to the named
revision or one of its ancestors as reported by the underlying VCS
tool, or the pseudo-version is not derived from any tag (that is,
has a "vX.0.0-" prefix before the date string and uses the lowest
major version appropriate to the module path).
2. The date string within the pseudo-version matches the UTC timestamp
of the revision as reported by the underlying VCS tool.
3. The short name of the revision within the pseudo-version (such as a
Git hash prefix) is the same as the short name reported by the
underlying cmd/go/internal/modfetch/codehost.Repo. Specifically, if
the short name is a SHA-1 prefix, it must use the same number of
hex digits (12) as codehost.ShortenSHA1.
4. The pseudo-version includes a '+incompatible' suffix only if it is
needed for the corresponding major version, and only if the
underlying module does not have a go.mod file.
We believe that all releases of the 'go' tool have generated
pseudo-versions that meet these constraints. However, a few
pseudo-versions edited by hand or generated by third-party tools do
not. If we discover invalid-but-benign pseudo-versions in widely-used
existing dependencies, we may choose to add a whitelist for those
specific path/version combinations.
―
To work around invalid dependencies in leaf modules, users may add a
'replace' directive from the invalid version to its valid equivalent.
Note that the go command's go.mod parser automatically resolves commit
hashes found in 'replace' directives to the appropriate
pseudo-versions, so in most cases one can write something like:
replace github.com/docker/docker v1.14.0-0.20190319215453-e7b5f7dbe98c => github.com/docker/docker e7b5f7dbe98c
and then run any 'go' command (such as 'go list' or 'go mod tidy') to
resolve it to an appropriate pseudo-version. Note that the invalid
version will still be used in minimal version selection, so this use
of 'replace' directives is an incomplete workaround.
―
One of the common use cases for higher-than-tagged pseudo-versions is
for projects that do parallel development on release branches. For
example, if a project cuts a 'v1.2' release branch at v1.2.0, they may
want future commits on the main branch to show up as pre-releases for
v1.3.0 rather than for v1.2.1 — especially if v1.2.1 is already tagged
on the release branch. (On the other hand, a backport of a patch to
the v1.2 branch should not show up as a pre-release for v1.3.0.)
To address this use-case, module authors can make use of our existing
support for pseudo-versions derived from pre-release tags: if the
author adds an explicit pre-release tag (such as 'v1.3.0-devel') to
the first commit after the branch, then the pseudo-versions for that
commit and its descendents will be derived from that tag and will sort
appropriately in version selection.

There is a subtle distinction between a value
*being* the zero value vs being *equal to* the zero value.
This was discussed at length in #31450.
Using "a zero value" in the docs suggests that there may
be more than zero value. That is possible on the "equal to
zero value" reading, but not the "is zero" reading that we
selected for the semantics of IsZero.
This change attempts to prevent any confusion on this front by
switching to "the zero value" in the documentation.
And while we're here, eliminate a double-space.

The very first paragraph on "Package initialization" stated that
"variables are initialized in declaration order, but after any
variables they might depend on". This phrasing was easily
misread as "declaration order is the first sorting criteria"
and then contradicted what the subsequent paragraphs spelled
out in precise detail.
Instead, variable initialization proceeds by repeatedly determining
a set of ready to initialize variables, and then selecting from that
set the variable declared earliest. That is, declaration order is the
second sorting criteria.
Also, for the purpose of variable initialization, declarations
introducing blank (_) variables are considered like any other
variables (their initialization expressions may have side-effects
and affect initialization order), even though blank identifiers
are not "declared".
This CL adds clarifying language regarding these two issues
and the supporting example.
Both gccgo and go/types implement this behavior. cmd/compile
has a long-standing issue (#22326).
The spec also did not state in which order multiple variables
initialized by a single (multi-value) initialization expression are
handled. This CL adds a clarifying paragraph: If any such variable
is initialized, all that declaration's variables are initialized at
the same time.
This behavior matches user expectation: We are not expecting to
observe partially initialized sets of variables in declarations
such as "var a, b, c = f()".
It also matches existing cmd/compile and go/types (but not gccgo)
behavior.
Finally, cmd/compile, gccgo, and go/types produce different
initialization orders in (esoteric) cases where hidden (not
detected with existing rules) dependencies exist. Added a
sentence and example clarifying how much leeway compilers have
in those situations. The goal is to preserve the ability to
use static initialization while at the same time maintain
the relative initialization order of variables with detected
dependencies.

This CL documents the new binary and octal integer literals,
hexadecimal floats, generalized imaginary literals and digit
separators for all number literals in the spec.
Added empty lines between abutting paragraphs in some places
(a more thorough cleanup can be done in a separate CL).
A minor detail: A single 0 was considered an octal zero per the
syntax (decimal integer literals always started with a non-zero
digit). The new octal literal syntax allows 0o and 0O prefixes
and when keeping the respective octal_lit syntax symmetric with
all the others (binary_lit, hex_lit), a single 0 is not automatically
part of it anymore. Rather than complicating the new octal_lit syntax
to include 0 as before, it is simpler (and more natural) to accept
a single 0 as part of a decimal_lit. This is purely a notational
change.
