This release addresss the following security issues:
- html: avoid quadratic complexity when coalescing text nodes
When coalescing adjacent text nodes in addText and fosterParent,
appending to an existing TextNode's Data via string concatenation
(n.Data += text) reallocated and copied the accumulated string on every
token. Inputs containing many short text runs separated by ignored end
tags (such as "a") caused O(n^2) allocations and byte copies.
Accumulate coalesced text in per-node byte slices during parsing and
materialize Data strings once at the end of parse.
Thanks to Markus Magnuson for reporting this issue.
This is CVE-2026-78661 and Go issue https://go.dev/issue/82224.
- html: check all ancestor namespace transitions when rendering raw text
In childTextNodesAreLiteral, walking up the tree previously stopped at
the nearest foreign ancestor once an HTML integration point was found.
However, that integration point may itself be a descendant of an element
that was foster-parented into a foreign namespace (such as or
fostered under ), causing a parser to resolve the
subtree in a different foreign namespace upon re-parsing the rendered
output.
Continue walking the full ancestor chain and verify that every
transition from a non-empty namespace occurs at an HTML integration
point before emitting literal text.

Replace the hardcoded list of supported OS/architecture combinations with
syntax validation using containerd/platforms.
This allows annotating manifests with platforms that are not explicitly
known to the CLI, while still rejecting missing or malformed values.
The validation uses a FormatAll/Parse roundtrip until containerd/platforms
provides a dedicated validation function.

Pass -w to the Go linker to reduce binary size while retaining the
symbol table for tools that inspect Go binaries.
For a linux/arm64 build, this reduces the CLI binary from 39,809,791
to 31,310,197 bytes: a saving of 8.5 MB (21.4%).
Place the default before caller-supplied GO_LDFLAGS so builds can
retain DWARF by passing GO_LDFLAGS="-w=0".

This release includes 1 security fix following the security policy:
- crypto/x509: mitigation for security concerns with a specific Certificate Authority
We're blocking trust in a small set of intermediate certificates due to specific security concerns around their operation.
Verify will now filter out chains which contain these intermediates, preventing them from being returned to the caller.
We highly recommend immediately upgrading to this release.
This is CVE-2026-111943 and Go issue https://go.dev/issue/82345.

Wrap errors in the OAuth manager instead of logging them, preserving
the underlying cause while allowing callers to detect startup failures.
Log failures at the fallback handler and scope the device-code login
result to its branch.

- Remove extra newline before message
- Include the token in the URL (instead of requiring the user to manually
enter it on the website).
- Improve the "call to action"; ENTER can be used to automatically open
the browser (but the user can manually open it instead), and CTRL-C can
be used to cancel the login.
- Remove the "Waiting for authentication in the browser…" message, which
could be confusing if no browser was opened (yet), instead print a message
after successfully requesting the browser to be opened.

Running "docker nonexistent --version" printed the CLI version and
exited 0, so it couldn't be used to check whether a command or plugin
is available. Without "--version" the same invocation fails with an
"unknown command" error.
When no built-in command or plugin matches, runDocker falls through to
executing the root command, and cobra handles the "--version" flag
before the root command reports the unknown command. Unset the root
command's version in that fallback, so the standard unknown-command
error is returned.
A global "--version" flag ("docker --version nonexistent") is parsed
before the command name and still prints the version, as do
"docker --version" and "docker nonexistent --help".
