For the v1.10.0-alpha1 release, where we weren't even feature-complete yet,
we included a callout box warning that features were incomplete and details
subject to change.
We're not expecting to issue another alpha before we reach the beta phase
during which we'll be aiming to change the design of these features as
little as possible, so it's time to remove that callout box.
In its place we now have a short statement about which versions of the
OCI Distribution protocol we support. Because some registries allow and
just ignore unrecognized properties in submitted manifests it is possible
that these features will work with older implementations, but such support
is not guaranteed by earlier versions of the specification. In practice,
OCI Distribution v1.1.0 is already quite well-deployed.

From feedback in alpha testing of the new OCI Distribution features we
learned that on some platforms Docker CLI automatically searches for
platform-specific credential helpers and uses them automatically when
found, but OpenTofu intentionally does not copy that behavior.
We'll now be explicit about that intentional difference in a callout box
in the documentation. This is unfortunately the kind of situation where
an affected person is unlikely to read the documentation to find out what
_isn't_ supported, and so this content is primarily intended to appear
in search results and other similar indirect querying, rather than by the
reader encountering it organically while reading the documentation. It's
therefore placed adjacent to the configuration option that someone might
use to solve the problem once they've learned about it.

The "tofu show" command has historically been difficult to extend to meet
new use-cases, such as showing the current configuration without creating
a plan, because it was designed to take zero or one arguments and then try
to guess what the one specified argument was intended to mean.
This commit introduces a new style where the type of object to inspect is
specified using command line option syntax, using one of two
mutually-exclusive options:
-state Show the latest state snapshot.
-plan=FILE Show the plan from the given saved plan file.
We expect that a future commit will extend this with a new "-config" option
to inspect the configuration rooted in the current working directory, and
possibly with "-module=DIR" to shallowly inspect a single module without
necessarily having to fully initialize it with all of its dependencies
first. However, both of those use-cases (and any others) are not in scope
for this commit, which is focused only on refactoring to make those future
use-cases possible.
The old mode of specifying neither option and providing zero or one
positional arguments is still supported for backward compatibility.
Notably, the legacy style is the only way to access the legacy behavior of
inspecting a specific state snapshot file from the local filesystem, which
has not often been used since Terraform v0.9 as we've moved away
from manual management of state files to the structure of state backends.
Those who _do_ still need that old behavior can still access it in the
old way, but there will be no new-style equivalent of it unless we learn
of a compelling use case for it.

This is a first draft of documentation describing our new capability to
treat artifacts in OCI Distribution repositories as a new kind of remote
module package.
This documentation includes both some caller-focused documentation that
extends our existing "Module Sources" page, and some documentation intended
more for the author of a module package describing how they could publish
their package as an OCI artifact that OpenTofu will accept.
As usual, we'll continue to refine this documentation based on feedback
during the prerelease period and beyond.

We are currently documenting how to manually edit the index manifest while
we wait for the ORAS CLI support for this to be finalized, but the initial
draft of these instructions missed the step of annotating each manifest
with the platform it's intended for.
(We intend to replace all of this manual setup with a single ORAS CLI
command once the associated functionality is finalized there. At the time
of writing this message, the ORAS project is preparing that functionality
for their forthcoming v1.3.0 release.)
