This text changed in CL 139099 to add "explicit" in front of "conversion".
But now "explicit conversion or assignment" reads like it might mean
"explicit [conversion or assignment]" when what is meant is
"[explicit conversion] or assignment". To make clear that explicit does
not apply to assignment, use "assignment or explicit conversion".

Instead, we put the issue to bed, perhaps not in perfect comfort

The spec currently provides a syntactic rule for receiver base types,
and a strict reading of those rules prohibits the use of type aliases
referring to pointer types as receiver types.
This strict interpretation breaks an assumed rule for aliases, which
is that a type literal can always be replaced by an alias denoting
that literal.
Furthermore, cmd/compile always accepted this new formulation of the
receiver type rules and so this change will simply validate what has
been implemented all along.

I've linked the gophers discord. It's a well administered discord which already got many members, but it was never officially linked. For many people it's a quality proof if a discord is linked on the official page. I think there are much more people out there, who would prefer to use discord instead of slack or irc.
The discord already got many users without even being promoted, so it's very likely there are many people who are interested in a discord, but they don't want to use unofficial discords. This discord shouldn't be seen as a competitor for the slack, it's a platform for those, who don't want to use slack.

Be clearer about it by defining the terms.
Also, state that integer to string conversions of the form string(x)

done so). See line 3948.

Since Go1.10, go test runs vet on the tests before executing them.
Moreover, the vet tool typechecks the package under analysis with
go/types before running. In Go1.10, a typechecking failure just caused
a warning to be printed. In Go1.11, a typechecking failure will cause
vet to exit with a fatal error (see Issue #21287).
This means that starting with Go1.11, tests that don't typecheck will
fail immediately. This would not normally be an issue, since a test
that doesn't typecheck shouldn't even compile, and it should already
be broken.
Unfortunately, there's a bug in gc that makes it accept programs with
unused variables inside a closure (Issue #3059). This means that a
test with an unused variable inside a closure, that compiled and
passed in Go1.10, will fail in the typechecking step of vet starting
with Go1.11.
Explain this in the 1.11 release notes.

The videos on the front page are always the same width, regardless of
the viewport width. These changes let the video fill the space given
to its container regardless of layout. It uses the standard hack for
making iframes responsive, but the videos are loaded at random and do
not have uniform aspect ratios so that information is injected into the
DOM using custom properties. If these are not supported, it falls back
to the same layout present before this change.
Note: this change also requires CL 108678 to complete the fix,
though either CL without the other is harmless.

In the binary sizes FAQ, the approximate size of a Go hello world
binary was said to be 1.5MB (it was about 1.6MB on go1.7 on
linux/amd64). Sadly, this is no longer true. A Go1.10 hello world is
2.0MB, and in 1.11 it'll be about 2.5MB.

I've reorganized the guide and rewritten large sections.
The structure is now more clear and logical, and can
be understood and navigated using the summary displayed at
the top of the page (before, the summary was confusing because
the guide contained H1s that were being ignored by the summary).
Both the initial onboarding process and the Gerrit
change submission process have been reworked to
include a concise checklist of steps that can be
read and understood in a few seconds, for people
that don't want or need to bother with details.
More in-depth descriptions have been moved into
separate sections, one per each checklist step.
This is by far the biggest improvement, as the previous
approach of having to read several pages just to understand
the requires steps was very scaring for beginners, in
addition of being harder to navigate.
GitHub pull requests have been integrated as a different
way to submit a change, suggested for first time contributors.
The review process has been described in more details,
documenting the workflow and the used conventions.
Most miscellanea have been moved into an "advanced
topics" chapter.
Paragraphs describing how to use git have been removed
to simplify reading. This guide should focus on Go contribution,
and not help users getting familiar with git, for which many
guides are available.

The EBNF production

was used in FunctionDecl, MethodDecl, and FunctionLit, but only
for the latter it shortened the syntax slightly.
This change "inlines" Function which simplifies FunctionDecl and
MethodDecl and gets rid of the Function production.
This has no impact on the specified language. Also, the Function
production is never referred to by the prose, so it's safe to
remove it from the spec.
Finally, neither go/ast nor go/parser have a representation of
this production via a corresponding node or parse function, so
no possibly valuable documentation is lost, either.

"named type" to "defined type" to avoid confusion with types denoted

Some of the old uses of "named types" remained; this change removes
them.
Now the spec consistently uses the terms:
- "defined type" for a type declared via a type definition
- "type name" for any name denoting an (alias or defined) type
- "alias" for a type name declared in an alias declaration
New prose is encouraged to avoid the term "named type" to counter-

A method expression is of the form T.m where T is a type and m
is a method of that type. The spec restricted T essentially to
a type name. Both cmd/compile and go/types accepted any type
syntactically, and a method expression was really just a form
of a selector expression x.f where x denotes a type.
This CL removes the spec syntax restriction from MethodExpr
to match the actual implementation. It also moves MethodExpr
from Operand to PrimaryExpr, because that's what it is.
It still keeps the separate notion of MethodExpr even though
it looks just like a selector expresion, since a MethodExpr
must start with a type rather than a value, and the spec's
syntax expresses this bit of semantics via distinct productions
(e.g., conversions look like calls but also must start with
a type).
