go1.20.8 (released 2023-09-06) includes two security fixes to the html/template
package, as well as bug fixes to the compiler, the go command, the runtime,
and the crypto/tls, go/types, net/http, and path/filepath packages. See the
Go 1.20.8 milestone on our issue tracker for details:

From the security mailing:
[security] Go 1.21.1 and Go 1.20.8 are released
Hello gophers,
We have just released Go versions 1.21.1 and 1.20.8, minor point releases.
These minor releases include 4 security fixes following the security policy:
- cmd/go: go.mod toolchain directive allows arbitrary execution
The go.mod toolchain directive, introduced in Go 1.21, could be leveraged to
execute scripts and binaries relative to the root of the module when the "go"
command was executed within the module. This applies to modules downloaded using
the "go" command from the module proxy, as well as modules downloaded directly
using VCS software.
Thanks to Juho Nurminen of Mattermost for reporting this issue.
This is CVE-2023-39320 and Go issue https://go.dev/issue/62198.
- html/template: improper handling of HTML-like comments within script contexts
The html/template package did not properly handle HMTL-like "<!--" and "-->"
comment tokens, nor hashbang "#!" comment tokens, in <script> contexts. This may
cause the template parser to improperly interpret the contents of <script>
contexts, causing actions to be improperly escaped. This could be leveraged to
perform an XSS attack.
Thanks to Takeshi Kaneko (GMO Cybersecurity by Ierae, Inc.) for reporting this
issue.
This is CVE-2023-39318 and Go issue https://go.dev/issue/62196.
- html/template: improper handling of special tags within script contexts
The html/template package did not apply the proper rules for handling occurrences
of "<script", "<!--", and "</script" within JS literals in <script> contexts.
This may cause the template parser to improperly consider script contexts to be
terminated early, causing actions to be improperly escaped. This could be
leveraged to perform an XSS attack.
Thanks to Takeshi Kaneko (GMO Cybersecurity by Ierae, Inc.) for reporting this
issue.
This is CVE-2023-39319 and Go issue https://go.dev/issue/62197.
- crypto/tls: panic when processing post-handshake message on QUIC connections
Processing an incomplete post-handshake message for a QUIC connection caused a panic.
Thanks to Marten Seemann for reporting this issue.
This is CVE-2023-39321 and CVE-2023-39322 and Go issue https://go.dev/issue/62266.

The SuccessStatus acted on the response's status code, and was used to return
early, before checking the same status code with HandleErrorResponse.
This patch combines both functions into a HandleHTTPResponseError, which
returns an error for "non-success" status-codes, which simplifies handling
of responses, and makes some logic slightly more idiomatic.

It was used for signing schema v1 manifests in tests which have now been
removed so there is no point in keeping these there anymore.

Use the non-exported function to all errors; there's currently no external
consumers of this function (perhaps it should be deprecated).

In case drvr.PutContent fails and returns error we'd have
some extra memory allocated, though in this case
(test with known size of the slice being iterated), that's fine.

Only some of the S3 storage driver calls were propagating context to the
S3 API calls. This commit updates the S3 storage drivers so the context
is propagated to all the S3 API calls.

This commit removes Registry v1 -> Registry v2 migration guide
as Registry v1 was deprecated long time ago and is no long longer
supported.
We also remove some references to "Future" roadmap which are wildly
outdated, too.

Storage drivers may be able to take advantage of the hint to start
their walk more efficiently.
For S3: The API takes a start-after parameter. Registries with many
repositories can drastically reduce calls to s3 by telling s3 to only
list results lexographically after the last parameter.
For the fallback: We can start deeper in the tree and avoid statting
the files and directories before the hint in a walk. For a filesystem
this improves performance a little, but many of the API based drivers
are currently treated like a filesystem, so this drastically improves
the performance of GCP and Azure blob.
