e53d10dc04 doc: mark range-over-func as documented
The language change for the accepted range-over-func proposal #61405
was documented in CL 590616. Remove the corresponding 'TODO' entry.

Also improve formatting slightly, and switch to preferred relative
links. They'll work better in the long term and in more contexts.

While here, also simplify the suggested line to preview release notes
locally: setting the -content='' flag explicitly is no longer required
as of CL 589936.

For #65614.

ca7d300509 Revert "runtime: remove GODEBUG=runtimecontentionstacks"
This reverts commit 87e930f728 (CL 585639)

Reason for revert: This is part of a patch series that changed the
handling of contended lock2/unlock2 calls, reducing the maximum
throughput of contended runtime.mutex values, and causing a performance
regression on applications where that is (or became) the bottleneck.

acc93dac83 doc/next: populate TODOs found with relnote todo
This is the first round of TODOs created based on relnote todo output.
There are many entries that need to be documented, expanded, reworded,
and this change makes progress on setting that up.

For this cycle, relnote todo implemented a simple heuristic of finding
CLs that mention accepted proposals (see issue 62376, or comment
https://go.dev/issue/62376#issuecomment-2101086794 specifically).
The "Items that don't need to be mentioned in Go 1.23 release notes but
are picked up by relnote todo." section in todo.md contains an attempt
at reviewing that list. The large number of items needed to be reviewed
made it impractical to spend much time on any individual one.

For #65614.

9eeb627f60 crypto/tls: add ech client support
This CL adds a (very opinionated) client-side ECH implementation.

In particular, if a user configures a ECHConfigList, by setting the
Config.EncryptedClientHelloConfigList, but we determine that none of
the configs are appropriate, we will not fallback to plaintext SNI, and
will instead return an error. It is then up to the user to decide if
they wish to fallback to plaintext themselves (by removing the config
list).

Additionally if Config.EncryptedClientHelloConfigList is provided, we
will not offer TLS support lower than 1.3, since negotiating any other
version, while offering ECH, is a hard error anyway. Similarly, if a
user wishes to fallback to plaintext SNI by using 1.2, they may do so
by removing the config list.

With regard to PSK GREASE, we match the boringssl  behavior, which does
not include PSK identities/binders in the outer hello when doing ECH.

If the server rejects ECH, we will return a ECHRejectionError error,
which, if provided by the server, will contain a ECHConfigList in the
RetryConfigList field containing configs that should be used if the user
wishes to retry. It is up to the user to replace their existing
Config.EncryptedClientHelloConfigList with the retry config list.

Fixes #63369

c96159c252 crypto/x509: cleanup signature generation
Centralizing some repetitive code, which would have prevented #45990.

This also fixes the deprecated Certificate.CreateCRL for RSA-PSS, not
that anyone cared, probably.

This has two other minor observable behavior changes: MD2 is now treated
as a completely unknown algorithm (why did we even have that!? removing
lets us treat hash == 0 as always meaning no prehash); and we now do the
signature verification self-check for all signing operations.

1b9dc3e178 runtime: increase profiling stack depth to 128
The current stack depth limit for alloc, mutex, block, threadcreate and
goroutine profiles of 32 frequently leads to truncated stack traces in
production applications. Increase the limit to 128 which is the same
size used by the execution tracer.

Create internal/profilerecord to define variants of the runtime's
StackRecord, MemProfileRecord and BlockProfileRecord types that can hold
arbitrarily big stack traces. Implement internal profiling APIs based on
these new types and use them for creating protobuf profiles and to act
as shims for the public profiling APIs using the old types.

This will lead to an increase in memory usage for applications that
use the impacted profile types and have stack traces exceeding the
current limit of 32. Those applications will also experience a slight
increase in CPU usage, but this will hopefully soon be mitigated via CL
540476 and 533258 which introduce frame pointer unwinding for the
relevant profile types.

For #43669.

a63907808d net/http: add field Cookie.Quoted bool
The current implementation of the http package strips double quotes
from the cookie-value during parsing, resulting in the serialized
cookie not including them. This patch addresses this limitation by
introducing a new field to track whether the original value was
enclosed in quotes.

Additionally, the internal representation of a cookie in the cookiejar
package has been adjusted to align with the new representation.

The syntax of cookies is outlined in RFC 6265 Section 4.1.1:
https://datatracker.ietf.org/doc/html/rfc6265\#section-4.1.1
