-# Release Notes
-
-The `initial` and `next` subdirectories of this directory are for release notes.
-
-## For developers
-
-Release notes should be added to `next` by editing existing files or creating
-new files. **Do not add RELNOTE=yes comments in CLs.** Instead, add a file to
-the CL (or ask the author to do so).
-
-At the end of the development cycle, the files will be merged by being
-concatenated in sorted order by pathname. Files in the directory matching the
-glob "*stdlib/*minor" are treated specially. They should be in subdirectories
-corresponding to standard library package paths, and headings for those package
-paths will be generated automatically.
-
-Files in this repo's `api/next` directory must have corresponding files in
-`doc/next/*stdlib/*minor`.
-The files should be in the subdirectory for the package with the new
-API, and should be named after the issue number of the API proposal.
-For example, if the directory `6-stdlib/99-minor` is present,
-then an `api/next` file with the line
-
-    pkg net/http, function F #12345
-
-should have a corresponding file named `doc/next/6-stdlib/99-minor/net/http/12345.md`.
-At a minimum, that file should contain either a full sentence or a TODO,
-ideally referring to a person with the responsibility to complete the note.
-
-If your CL addresses an accepted proposal, mention the proposal issue number in
-your release note in the form `/issue/NUMBER`. A link to the issue in the text
-will have this form (see below). If you don't want to mention the issue in the
-text, add it as a comment:
-```
-<!-- go.dev/issue/12345 -->
-```
-If an accepted proposal is mentioned in a CL but not in the release notes, it will be
-flagged as a TODO by the automated tooling. That is true even for proposals that add API.
-
-Use the following forms in your markdown:
-
-	[http.Request]                     # symbol documentation; auto-linked as in Go doc strings
-	[Request]                          # short form, for symbols in the package being documented
-	[net/http]                         # package link
-	[#12345](/issue/12345)             # GitHub issues
-	[CL 6789](/cl/6789)                # Gerrit changelists
-
-To preview `next` content in merged form using a local instance of the website, run:
-
-```
-go run golang.org/x/website/cmd/golangorg@latest -goroot=..
-```
-
-Then open http://localhost:6060/doc/next. Refresh the page to see your latest edits.
-
-## For the release team
-
-The `relnote` tool, at `golang.org/x/build/cmd/relnote`, operates on the files
-in `doc/next`.
-
-As a release cycle nears completion, run `relnote todo` to get a list of
-unfinished release note work.
-
-To prepare the release notes for a release, run `relnote generate`.
-That will merge the `.md` files in `next` into a single file.
-Atomically (as close to it as possible) add that file to `_content/doc` directory
-of the website repository and remove the `doc/next` directory in this repository.
-
-To begin the next release development cycle, populate the contents of `next`
-with those of `initial`. From the repo root:
-
-    > cd doc
-    > cp -R initial/ next
-
-Then edit `next/1-intro.md` to refer to the next version.

-### Go 1.26
-
-Go 1.26 added a new `httpcookiemaxnum` setting that controls the maximum number
-of cookies that net/http will accept when parsing HTTP headers. If the number of
-cookie in a header exceeds the number set in `httpcookiemaxnum`, cookie parsing
-will fail early. The default value is `httpcookiemaxnum=3000`. Setting
-`httpcookiemaxnum=0` will allow the cookie parsing to accept an indefinite
-number of cookies. To avoid denial of service attacks, this setting and default
-was backported to Go 1.25.2 and Go 1.24.8.
-
-Go 1.26 added a new `urlmaxqueryparams` setting that controls the maximum number
-of query parameters that net/url will accept when parsing a URL-encoded query string.
-If the number of parameters exceeds the number set in `urlmaxqueryparams`,
-parsing will fail early. The default value is `urlmaxqueryparams=10000`.
-Setting `urlmaxqueryparams=0` disables the limit. To avoid denial of service
-attacks, this setting and default was backported to Go 1.25.6 and Go 1.24.12.
-
-Go 1.26 added a new `urlstrictcolons` setting that controls whether `net/url.Parse`
-allows malformed hostnames containing colons outside of a bracketed IPv6 address.
-The default `urlstrictcolons=1` rejects URLs such as `http://localhost:1:2` or `http://::1/`.
-Colons are permitted as part of a bracketed IPv6 address, such as `http://[::1]/`.
-
-Go 1.26 enabled two additional post-quantum key exchange mechanisms:
-SecP256r1MLKEM768 and SecP384r1MLKEM1024. The default can be reverted using the
-[`tlssecpmlkem` setting](/pkg/crypto/tls/#Config.CurvePreferences).
-
-Go 1.26 added a new `tracebacklabels` setting that controls the inclusion of
-goroutine labels set through the the `runtime/pprof` package. Setting `tracebacklabels=1`
-includes these key/value pairs in the goroutine status header of runtime
-tracebacks and debug=2 runtime/pprof stack dumps. This format may change in the future.
-(see go.dev/issue/76349)
-
-Go 1.26 added a new `cryptocustomrand` setting that controls whether most crypto/...
-APIs ignore the random `io.Reader` parameter. For Go 1.26, it defaults
-to `cryptocustomrand=0`, ignoring the random parameters. Using `cryptocustomrand=1`
-reverts to the pre-Go 1.26 behavior.
-
-### Go 1.25
-
-Go 1.25 added a new `decoratemappings` setting that controls whether the Go
-runtime annotates OS anonymous memory mappings with context about their
-purpose. These annotations appear in /proc/self/maps and /proc/self/smaps as
-"[anon: Go: ...]". This setting is only used on Linux. For Go 1.25, it defaults
-to `decoratemappings=1`, enabling annotations. Using `decoratemappings=0`
-reverts to the pre-Go 1.25 behavior. This setting is fixed at program startup
-time, and can't be modified by changing the `GODEBUG` environment variable
-after the program starts.
-
-Go 1.25 added a new `embedfollowsymlinks` setting that controls whether the
-Go command will follow symlinks to regular files embedding files.
-The default value `embedfollowsymlinks=0` does not allow following
-symlinks. `embedfollowsymlinks=1` will allow following symlinks.
-
-Go 1.25 added a new `containermaxprocs` setting that controls whether the Go
-runtime will consider cgroup CPU limits when setting the default GOMAXPROCS.
-The default value `containermaxprocs=1` will use cgroup limits in addition to
-the total logical CPU count and CPU affinity. `containermaxprocs=0` will
-disable consideration of cgroup limits. This setting only affects Linux.
-
-Go 1.25 added a new `updatemaxprocs` setting that controls whether the Go
-runtime will periodically update GOMAXPROCS for new CPU affinity or cgroup
-limits. The default value `updatemaxprocs=1` will enable periodic updates.
-`updatemaxprocs=0` will disable periodic updates.
-
-Go 1.25 disabled SHA-1 signature algorithms in TLS 1.2 according to RFC 9155.
-The default can be reverted using the `tlssha1=1` setting.
-
-Go 1.25 switched to SHA-256 to fill in missing SubjectKeyId in
-crypto/x509.CreateCertificate. The setting `x509sha256skid=0` reverts to SHA-1.
-
-Go 1.25 corrected the semantics of contention reports for runtime-internal locks,
-and so removed the [`runtimecontentionstacks` setting](/pkg/runtime#hdr-Environment_Variables).
-
-Go 1.25 (starting with Go 1.25 RC 2) disabled build information stamping when
-multiple VCS are detected due to concerns around VCS injection attacks. This
-behavior and setting was backported to Go 1.24.5 and Go 1.23.11. This behavior
-can be renabled with the setting `allowmultiplevcs=1`.
-
-### Go 1.24
-
-Go 1.24 added a new `fips140` setting that controls whether the Go
-Cryptographic Module operates in FIPS 140-3 mode.
-The possible values are:
-- "off": no special support for FIPS 140-3 mode. This is the default.
-- "on": the Go Cryptographic Module operates in FIPS 140-3 mode.
-- "only": like "on", but cryptographic algorithms not approved by
-  FIPS 140-3 return an error or panic.
-For more information, see [FIPS 140-3 Compliance](/doc/security/fips140).
-This setting is fixed at program startup time, and can't be modified
-by changing the `GODEBUG` environment variable after the program starts.
-
-Go 1.24 changed the global [`math/rand.Seed`](/pkg/math/rand/#Seed) to be a
-no-op. This behavior is controlled by the `randseednop` setting.
-For Go 1.24 it defaults to `randseednop=1`.
-Using `randseednop=0` reverts to the pre-Go 1.24 behavior.
-
-Go 1.24 added new values for the `multipathtcp` setting.
-The possible values for `multipathtcp` are now:
-- "0": disable MPTCP on dialers and listeners by default
-- "1": enable MPTCP on dialers and listeners by default
-- "2": enable MPTCP on listeners only by default
-- "3": enable MPTCP on dialers only by default
-
-For Go 1.24, it now defaults to multipathtcp="2", thus
-enabled by default on listeners. Using multipathtcp="0" reverts to the
-pre-Go 1.24 behavior.
-
-Go 1.24 changed the behavior of `go test -json` to emit build errors as JSON
-instead of text.
-These new JSON events are distinguished by new `Action` values,
-but can still cause problems with CI systems that aren't robust to these events.
-This behavior can be controlled with the `gotestjsonbuildtext` setting.
-Using `gotestjsonbuildtext=1` restores the 1.23 behavior.
-This setting will be removed in a future release, Go 1.28 at the earliest.
-
-Go 1.24 changed [`crypto/rsa`](/pkg/crypto/rsa) to require RSA keys to be at
-least 1024 bits. This behavior can be controlled with the `rsa1024min` setting.
-Using `rsa1024min=0` restores the Go 1.23 behavior.
-
-Go 1.24 introduced a mechanism for enabling platform specific Data Independent
-Timing (DIT) modes in the [`crypto/subtle`](/pkg/crypto/subtle) package. This
-mode can be enabled for an entire program with the `dataindependenttiming` setting.
-For Go 1.24 it defaults to `dataindependenttiming=0`. There is no change in default
-behavior from Go 1.23 when `dataindependenttiming` is unset.
-Using `dataindependenttiming=1` enables the DIT mode for the entire Go program.
-When enabled, DIT will be enabled when calling into C from Go. When enabled,
-calling into Go code from C will enable DIT, and disable it before returning to
-C if it was not enabled when Go code was entered.
-This currently only affects arm64 programs. For all other platforms it is a no-op.
-
-Go 1.24 removed the `x509sha1` setting.  `crypto/x509` no longer supports verifying
-signatures on certificates that use SHA-1 based signature algorithms.
-
-Go 1.24 changes the default value of the [`x509usepolicies`
-setting.](/pkg/crypto/x509/#CreateCertificate) from `0` to `1`. When marshalling
-certificates, policies are now taken from the
-[`Certificate.Policies`](/pkg/crypto/x509/#Certificate.Policies) field rather
-than the
-[`Certificate.PolicyIdentifiers`](/pkg/crypto/x509/#Certificate.PolicyIdentifiers)
-field by default.
-
-Go 1.24 enabled the post-quantum key exchange mechanism
-X25519MLKEM768 by default. The default can be reverted using the
-[`tlsmlkem` setting](/pkg/crypto/tls/#Config.CurvePreferences).
-This can be useful when dealing with buggy TLS servers that do not handle large records correctly,
-causing a timeout during the handshake (see [TLS post-quantum TL;DR fail](https://tldr.fail/)).
-Go 1.24 also removed X25519Kyber768Draft00 and the Go 1.23 `tlskyber` setting.
-
-Go 1.24 made [`ParsePKCS1PrivateKey`](/pkg/crypto/x509/#ParsePKCS1PrivateKey)
-use and validate the CRT parameters in the encoded private key. This behavior
-can be controlled with the `x509rsacrt` setting. Using `x509rsacrt=0` restores
-the Go 1.23 behavior.
-
-### Go 1.23
-
-Go 1.23 changed the channels created by package time to be unbuffered
-(synchronous), which makes correct use of the [`Timer.Stop`](/pkg/time/#Timer.Stop)
-and [`Timer.Reset`](/pkg/time/#Timer.Reset) method results much easier.
-The [`asynctimerchan` setting](/pkg/time/#NewTimer) disables this change.
-There are no runtime metrics for this change,
-This setting will be removed in Go 1.27.
-
-Go 1.23 changed the mode bits reported by [`os.Lstat`](/pkg/os#Lstat) and [`os.Stat`](/pkg/os#Stat)
-for reparse points, which can be controlled with the `winsymlink` setting.
-As of Go 1.23 (`winsymlink=1`), mount points no longer have [`os.ModeSymlink`](/pkg/os#ModeSymlink)
-set, and reparse points that are not symlinks, Unix sockets, or dedup files now
-always have [`os.ModeIrregular`](/pkg/os#ModeIrregular) set. As a result of these changes,
-[`filepath.EvalSymlinks`](/pkg/path/filepath#EvalSymlinks) no longer evaluates
-mount points, which was a source of many inconsistencies and bugs.
-At previous versions (`winsymlink=0`), mount points are treated as symlinks,
-and other reparse points with non-default [`os.ModeType`](/pkg/os#ModeType) bits
-(such as [`os.ModeDir`](/pkg/os#ModeDir)) do not have the `ModeIrregular` bit set.
-
-Go 1.23 changed [`os.Readlink`](/pkg/os#Readlink) and [`filepath.EvalSymlinks`](/pkg/path/filepath#EvalSymlinks)
-to avoid trying to normalize volumes to drive letters, which was not always even possible.
-This behavior is controlled by the `winreadlinkvolume` setting.
-For Go 1.23, it defaults to `winreadlinkvolume=1`.
-Previous versions default to `winreadlinkvolume=0`.
-
-Go 1.23 enabled the experimental post-quantum key exchange mechanism
-X25519Kyber768Draft00 by default. The default can be reverted using the
-[`tlskyber` setting](/pkg/crypto/tls/#Config.CurvePreferences).
-This can be useful when dealing with buggy TLS servers that do not handle large records correctly,
-causing a timeout during the handshake (see [TLS post-quantum TL;DR fail](https://tldr.fail/)).
-
-Go 1.23 changed the behavior of
-[crypto/x509.ParseCertificate](/pkg/crypto/x509/#ParseCertificate) to reject
-serial numbers that are negative. This change can be reverted with
-the [`x509negativeserial` setting](/pkg/crypto/x509/#ParseCertificate).
-
-Go 1.23 re-enabled support in html/template for ECMAScript 6 template literals by default.
-The [`jstmpllitinterp` setting](/pkg/html/template#hdr-Security_Model) no longer has
-any effect.
-
-Go 1.23 changed the default TLS cipher suites used by clients and servers when
-not explicitly configured, removing 3DES cipher suites. The default can be reverted
-using the [`tls3des` setting](/pkg/crypto/tls/#Config.CipherSuites).
-This setting will be removed in Go 1.27.
-
-Go 1.23 changed the behavior of [`tls.X509KeyPair`](/pkg/crypto/tls#X509KeyPair)
-and [`tls.LoadX509KeyPair`](/pkg/crypto/tls#LoadX509KeyPair) to populate the
-Leaf field of the returned [`tls.Certificate`](/pkg/crypto/tls#Certificate).
-This behavior is controlled by the `x509keypairleaf` setting. For Go 1.23, it
-defaults to `x509keypairleaf=1`. Previous versions default to
-`x509keypairleaf=0`.
-This setting will be removed in Go 1.27.
-
-Go 1.23 changed
-[`net/http.ServeContent`](/pkg/net/http#ServeContent),
-[`net/http.ServeFile`](/pkg/net/http#ServeFile), and
-[`net/http.ServeFS`](/pkg/net/http#ServeFS) to
-remove Cache-Control, Content-Encoding, Etag, and Last-Modified headers
-when serving an error. This behavior is controlled by
-the [`httpservecontentkeepheaders` setting](/pkg/net/http#ServeContent).
-Using `httpservecontentkeepheaders=1` restores the pre-Go 1.23 behavior.

-Go release cycle considerations
-===============================
-
-Applying changes to packages that are vendored follows the considerations
-written down at go.dev/s/release.
-
-When the Go tree is open for development, a specific change may be pulled in
-at any time that it is needed. During the release freeze, the bar for changes
-in vendored packages is the same as it is for changes in non-vendored packages.
-After a major release is out, minor Go releases follow a more involved process
-documented at go.dev/wiki/MinorReleases#cherry-pick-cls-for-vendored-golangorgx-packages.
-
-In addition to individual updates that happen on demand, all dependencies in
-the std and cmd modules are updated to their latest available versions at least
-twice during every major release cycle. This is done to avoid the possibility of
-some dependencies being left on very old versions and in turn make their eventual
-update more disruptive. This recurring process is tracked in go.dev/issue/36905.
-The golang.org/x/build/cmd/updatestd command exists to assist with that process.
