* go1.22 (released 2024-02-06) is a major release of Go. go1.22.x minor
releases will be provided through February 2024.
https://github.com/golang/go/wiki/Go-Release-Cycle go1.22 arrives six months
after go1.21. Most of its changes are in the implementation of the
toolchain, runtime, and libraries. As always, the release maintains the Go 1
promise of compatibility. We expect almost all Go programs to continue to
compile and run as before. (bsc#1218424)
* Language change: go1.22 makes two changes to for loops. Previously, the
variables declared by a for loop were created once and updated by each
iteration. In go1.22, each iteration of the loop creates new variables, to
avoid accidental sharing bugs. The transition support tooling described in
the proposal continues to work in the same way it did in Go 1.21.
* Language change: For loops may now range over integers
* Language change: go1.22 includes a preview of a language change we are
considering for a future version of Go: range-over-function iterators.
Building with GOEXPERIMENT=rangefunc enables this feature.
* go command: Commands in workspaces can now use a vendor directory containing
the dependencies of the workspace. The directory is created by go work
vendor, and used by build commands when the -mod flag is set to vendor,
which is the default when a workspace vendor directory is present. Note that
the vendor directory's contents for a workspace are different from those of
a single module: if the directory at the root of a workspace also contains
one of the modules in the workspace, its vendor directory can contain the
dependencies of either the workspace or of the module, but not both.
* go get is no longer supported outside of a module in the legacy GOPATH mode
(that is, with GO111MODULE=off). Other build commands, such as go build and
go test, will continue to work indefinitely for legacy GOPATH programs.
* go mod init no longer attempts to import module requirements from
configuration files for other vendoring tools (such as Gopkg.lock).
* go test -cover now prints coverage summaries for covered packages that do
not have their own test files. Prior to Go 1.22 a go test -cover run for
such a package would report: ? mymod/mypack [no test files] and now with
go1.22, functions in the package are treated as uncovered: mymod/mypack
coverage: 0.0% of statements Note that if a package contains no executable
code at all, we can't report a meaningful coverage percentage; for such
packages the go tool will continue to report that there are no test files.
* trace: The trace tool's web UI has been gently refreshed as part of the work
to support the new tracer, resolving several issues and improving the
readability of various sub-pages. The web UI now supports exploring traces
in a thread-oriented view. The trace viewer also now displays the full
duration of all system calls. These improvements only apply for viewing
traces produced by programs built with go1.22 or newer. A future release
will bring some of these improvements to traces produced by older version of
Go.
* vet: References to loop variables The behavior of the vet tool has changed
to match the new semantics (see above) of loop variables in go1.22. When
analyzing a file that requires go1.22 or newer (due to its go.mod file or a
per-file build constraint), vetcode> no longer reports references to loop
variables from within a function literal that might outlive the iteration of
the loop. In Go 1.22, loop variables are created anew for each iteration, so
such references are no longer at risk of using a variable after it has been
updated by the loop.
* vet: New warnings for missing values after append The vet tool now reports
calls to append that pass no values to be appended to the slice, such as
slice = append(slice). Such a statement has no effect, and experience has
shown that is nearly always a mistake.
* vet: New warnings for deferring time.Since The vet tool now reports a non-
deferred call to time.Since(t) within a defer statement. This is equivalent
to calling time.Now().Sub(t) before the defer statement, not when the
deferred function is called. In nearly all cases, the correct code requires
deferring the time.Since call.
* vet: New warnings for mismatched key-value pairs in log/slog calls The vet
tool now reports invalid arguments in calls to functions and methods in the
structured logging package, log/slog, that accept alternating key/value
pairs. It reports calls where an argument in a key position is neither a
string nor a slog.Attr, and where a final key is missing its value.
* runtime: The runtime now keeps type-based garbage collection metadata nearer
to each heap object, improving the CPU performance (latency or throughput)
of Go programs by 1-3%. This change also reduces the memory overhead of the
majority Go programs by approximately 1% by deduplicating redundant
metadata. Some programs may see a smaller improvement because this change
adjusts the size class boundaries of the memory allocator, so some objects
may be moved up a size class. A consequence of this change is that some
objects' addresses that were previously always aligned to a 16 byte (or
higher) boundary will now only be aligned to an 8 byte boundary. Some
programs that use assembly instructions that require memory addresses to be
more than 8-byte aligned and rely on the memory allocator's previous
alignment behavior may break, but we expect such programs to be rare. Such
programs may be built with GOEXPERIMENT=noallocheaders to revert to the old
metadata layout and restore the previous alignment behavior, but package
owners should update their assembly code to avoid the alignment assumption,
as this workaround will be removed in a future release.
* runtime: On the windows/amd64 port, programs linking or loading Go libraries
built with -buildmode=c-archive or -buildmode=c-shared can now use the
SetUnhandledExceptionFilter Win32 function to catch exceptions not handled
by the Go runtime. Note that this was already supported on the windows/386
port.
* compiler: Profile-guided Optimization (PGO) builds can now devirtualize a
higher proportion of calls than previously possible. Most programs from a
representative set of Go programs now see between 2 and 14% improvement from
enabling PGO.
* compiler: The compiler now interleaves devirtualization and inlining, so
interface method calls are better optimized.
* compiler: go1.22 also includes a preview of an enhanced implementation of
the compiler's inlining phase that uses heuristics to boost inlinability at
call sites deemed "important" (for example, in loops) and discourage
inlining at call sites deemed "unimportant" (for example, on panic paths).
Building with GOEXPERIMENT=newinliner enables the new call-site heuristics;
see issue #61502 for more info and to provide feedback.
* linker: The linker's -s and -w flags are now behave more consistently across
all platforms. The -w flag suppresses DWARF debug information generation.
The -s flag suppresses symbol table generation. The -s flag also implies the
-w flag, which can be negated with -w=0. That is, -s -w=0 will generate a
binary with DWARF debug information generation but without the symbol table.
* linker: On ELF platforms, the -B linker flag now accepts a special form:
with -B gobuildid, the linker will generate a GNU build ID (the ELF
NT_GNU_BUILD_ID note) derived from the Go build ID.
* linker: On Windows, when building with -linkmode=internal, the linker now
preserves SEH information from C object files by copying the .pdata and
.xdata sections into the final binary. This helps with debugging and
profiling binaries using native tools, such as WinDbg. Note that until now,
C functions' SEH exception handlers were not being honored, so this change
may cause some programs to behave differently. -linkmode=external is not
affected by this change, as external linkers already preserve SEH
information.
* bootstrap: As mentioned in the Go 1.20 release notes, go1.22 now requires
the final point release of Go 1.20 or later for bootstrap. We expect that Go
1.24 will require the final point release of go1.22 or later for bootstrap.
* core library: New math/rand/v2 package: go1.22 includes the first “v2”
package in the standard library, math/rand/v2. The changes compared to
math/rand are detailed in proposal go#61716. The most important changes are:
* The Read method, deprecated in math/rand, was not carried forward for math/rand/v2. (It remains available in math/rand.) The vast majority of calls to Read should use crypto/rand’s Read instead. Otherwise a custom Read can be constructed using the Uint64 method.
* The global generator accessed by top-level functions is unconditionally randomly seeded. Because the API guarantees no fixed sequence of results, optimizations like per-thread random generator states are now possible.
* The Source interface now has a single Uint64 method; there is no Source64 interface.
* Many methods now use faster algorithms that were not possible to adopt in math/rand because they changed the output streams.
* The Intn, Int31, Int31n, Int63, and Int64n top-level functions and methods from math/rand are spelled more idiomatically in math/rand/v2: IntN, Int32, Int32N, Int64, and Int64N. There are also new top-level functions and methods Uint32, Uint32N, Uint64, Uint64N, Uint, and UintN.
* The new generic function N is like Int64N or Uint64N but works for any integer type. For example a random duration from 0 up to 5 minutes is rand.N(5*time.Minute).
* The Mitchell & Reeds LFSR generator provided by math/rand’s Source has been replaced by two more modern pseudo-random generator sources: ChaCha8 PCG. ChaCha8 is a new, cryptographically strong random number generator roughly similar to PCG in efficiency. ChaCha8 is the algorithm used for the top-level functions in math/rand/v2. As of go1.22, math/rand's top-level functions (when not explicitly seeded) and the Go runtime also use ChaCha8 for randomness.
* We plan to include an API migration tool in a future release, likely Go 1.23.
* core library: New go/version package: The new go/version package implements
functions for validating and comparing Go version strings.
* core library: Enhanced routing patterns: HTTP routing in the standard
library is now more expressive. The patterns used by net/http.ServeMux have
been enhanced to accept methods and wildcards. This change breaks backwards
compatibility in small ways, some obvious—patterns with "{" and "}" behave
differently— and some less so—treatment of escaped paths has been improved.
The change is controlled by a GODEBUG field named httpmuxgo121. Set
httpmuxgo121=1 to restore the old behavior.
* Minor changes to the library As always, there are various minor changes and
updates to the library, made with the Go 1 promise of compatibility in mind.
There are also various performance improvements, not enumerated here.
* archive/tar: The new method Writer.AddFS adds all of the files from an fs.FS
to the archive.
* archive/zip: The new method Writer.AddFS adds all of the files from an fs.FS
to the archive.
* bufio: When a SplitFunc returns ErrFinalToken with a nil token, Scanner will
now stop immediately. Previously, it would report a final empty token before
stopping, which was usually not desired. Callers that do want to report a
final empty token can do so by returning []byte{} rather than nil.
* cmp: The new function Or returns the first in a sequence of values that is
not the zero value.
* crypto/tls: ConnectionState.ExportKeyingMaterial will now return an error
unless TLS 1.3 is in use, or the extended_master_secret extension is
supported by both the server and client. crypto/tls has supported this
extension since Go 1.20. This can be disabled with the tlsunsafeekm=1
GODEBUG setting.
* crypto/tls: By default, the minimum version offered by crypto/tls servers is
now TLS 1.2 if not specified with config.MinimumVersion, matching the
behavior of crypto/tls clients. This change can be reverted with the
tls10server=1 GODEBUG setting.
* crypto/tls: By default, cipher suites without ECDHE support are no longer
offered by either clients or servers during pre-TLS 1.3 handshakes. This
change can be reverted with the tlsrsakex=1 GODEBUG setting.
* crypto/x509: The new CertPool.AddCertWithConstraint method can be used to
add customized constraints to root certificates to be applied during chain
building.
* crypto/x509: On Android, root certificates will now be loaded from
/data/misc/keychain/certs-added as well as /system/etc/security/cacerts.
* crypto/x509: A new type, OID, supports ASN.1 Object Identifiers with
individual components larger than 31 bits. A new field which uses this type,
Policies, is added to the Certificate struct, and is now populated during
parsing. Any OIDs which cannot be represented using a asn1.ObjectIdentifier
will appear in Policies, but not in the old PolicyIdentifiers field. When
calling CreateCertificate, the Policies field is ignored, and policies are
taken from the PolicyIdentifiers field. Using the x509usepolicies=1 GODEBUG
setting inverts this, populating certificate policies from the Policies
field, and ignoring the PolicyIdentifiers field. We may change the default
value of x509usepolicies in Go 1.23, making Policies the default field for
marshaling.
* database/sql: The new Null[T] type provide a way to scan nullable columns
for any column types.
* debug/elf: Constant R_MIPS_PC32 is defined for use with MIPS64 systems.
Additional R_LARCH_* constants are defined for use with LoongArch systems.
* encoding: The new methods AppendEncode and AppendDecode added to each of the
Encoding types in the packages encoding/base32, encoding/base64, and
encoding/hex simplify encoding and decoding from and to byte slices by
taking care of byte slice buffer management.
* encoding: The methods base32.Encoding.WithPadding and
base64.Encoding.WithPadding now panic if the padding argument is a negative
value other than NoPadding.
* encoding/json: Marshaling and encoding functionality now escapes '\b' and
'\f' characters as \b and \f instead of \u0008 and \u000c.
* go/ast: The following declarations related to syntactic identifier
resolution are now deprecated: Ident.Obj, Object, Scope, File.Scope,
File.Unresolved, Importer, Package, NewPackage. In general, identifiers
cannot be accurately resolved without type information. Consider, for
example, the identifier K in T{K: ""}: it could be the name of a local
variable if T is a map type, or the name of a field if T is a struct type.
New programs should use the go/types package to resolve identifiers; see
Object, Info.Uses, and Info.Defs for details.
* go/ast: The new ast.Unparen function removes any enclosing parentheses from
an expression.
* go/types: The new Alias type represents type aliases. Previously, type
aliases were not represented explicitly, so a reference to a type alias was
equivalent to spelling out the aliased type, and the name of the alias was
lost. The new representation retains the intermediate Alias. This enables
improved error reporting (the name of a type alias can be reported), and
allows for better handling of cyclic type declarations involving type
aliases. In a future release, Alias types will also carry type parameter
information. The new function Unalias returns the actual type denoted by an
Alias type (or any other Type for that matter).
* go/types: Because Alias types may break existing type switches that do not
know to check for them, this functionality is controlled by a GODEBUG field
named gotypesalias. With gotypesalias=0, everything behaves as before, and
Alias types are never created. With gotypesalias=1, Alias types are created
and clients must expect them. The default is gotypesalias=0. In a future
release, the default will be changed to gotypesalias=1. Clients of go/types
are urged to adjust their code as soon as possible to work with
gotypesalias=1 to eliminate problems early.
* go/types: The Info struct now exports the FileVersions map which provides
per-file Go version information.
* go/types: The new helper method PkgNameOf returns the local package name for
the given import declaration.
* go/types: The implementation of SizesFor has been adjusted to compute the
same type sizes as the compiler when the compiler argument for SizesFor is
"gc". The default Sizes implementation used by the type checker is now
types.SizesFor("gc", "amd64").
* go/types: The start position (Pos) of the lexical environment block (Scope)
that represents a function body has changed: it used to start at the opening
curly brace of the function body, but now starts at the function's func
token.
* html/template: Javascript template literals may now contain Go template
actions, and parsing a template containing one will no longer return
ErrJSTemplate. Similarly the GODEBUG setting jstmpllitinterp no longer has
any effect.
* io: The new SectionReader.Outer method returns the ReaderAt, offset, and
size passed to NewSectionReader.
* log/slog: The new SetLogLoggerLevel function controls the level for the
bridge between the `slog` and `log` packages. It sets the minimum level for
calls to the top-level `slog` logging functions, and it sets the level for
calls to `log.Logger` that go through `slog`.
* math/big: The new method Rat.FloatPrec computes the number of fractional
decimal digits required to represent a rational number accurately as a
floating-point number, and whether accurate decimal representation is
possible in the first place.
* net: When io.Copy copies from a TCPConn to a UnixConn, it will now use
Linux's splice(2) system call if possible, using the new method
TCPConn.WriteTo.
* net: The Go DNS Resolver, used when building with "-tags=netgo", now
searches for a matching name in the Windows hosts file, located at
%SystemRoot%\System32\drivers\etc\hosts, before making a DNS query.
* net/http: The new functions ServeFileFS, FileServerFS, and
NewFileTransportFS are versions of the existing ServeFile, FileServer, and
NewFileTransport, operating on an fs.FS.
* net/http: The HTTP server and client now reject requests and responses
containing an invalid empty Content-Length header. The previous behavior may
be restored by setting GODEBUG field httplaxcontentlength=1.
* net/http: The new method Request.PathValue returns path wildcard values from
a request and the new method Request.SetPathValue sets path wildcard values
on a request.
* net/http/cgi: When executing a CGI process, the PATH_INFO variable is now
always set to the empty string or a value starting with a / character, as
required by RFC 3875. It was previously possible for some combinations of
Handler.Root and request URL to violate this requirement.
* net/netip: The new AddrPort.Compare method compares two AddrPorts.
* os: On Windows, the Stat function now follows all reparse points that link
to another named entity in the system. It was previously only following
IO_REPARSE_TAG_SYMLINK and IO_REPARSE_TAG_MOUNT_POINT reparse points.
* os: On Windows, passing O_SYNC to OpenFile now causes write operations to go
directly to disk, equivalent to O_SYNC on Unix platforms.
* os: On Windows, the ReadDir, File.ReadDir, File.Readdir, and
File.Readdirnames functions now read directory entries in batches to reduce
the number of system calls, improving performance up to 30%.
* os: When io.Copy copies from a File to a net.UnixConn, it will now use
Linux's sendfile(2) system call if possible, using the new method
File.WriteTo.
* os/exec: On Windows, LookPath now ignores empty entries in %PATH%, and
returns ErrNotFound (instead of ErrNotExist) if no executable file extension
is found to resolve an otherwise-unambiguous name.
* os/exec: On Windows, Command and Cmd.Start no longer call LookPath if the
path to the executable is already absolute and has an executable file
extension. In addition, Cmd.Start no longer writes the resolved extension
back to the Path field, so it is now safe to call the String method
concurrently with a call to Start.
* reflect: The Value.IsZero method will now return true for a floating-point
or complex negative zero, and will return true for a struct value if a blank
field (a field named _) somehow has a non-zero value. These changes make
IsZero consistent with comparing a value to zero using the language ==
operator.
* reflect: The PtrTo function is deprecated, in favor of PointerTo.
* reflect: The new function TypeFor returns the Type that represents the type
argument T. Previously, to get the reflect.Type value for a type, one had to
use reflect.TypeOf((*T)(nil)).Elem(). This may now be written as
reflect.TypeForT.
* runtime/metrics: Four new histogram metrics
/sched/pauses/stopping/gc:seconds, /sched/pauses/stopping/other:seconds,
/sched/pauses/total/gc:seconds, and /sched/pauses/total/other:seconds
provide additional details about stop-the-world pauses. The "stopping"
metrics report the time taken from deciding to stop the world until all
goroutines are stopped. The "total" metrics report the time taken from
deciding to stop the world until it is started again.
* runtime/metrics: The /gc/pauses:seconds metric is deprecated, as it is
equivalent to the new /sched/pauses/total/gc:seconds metric.
* runtime/metrics: /sync/mutex/wait/total:seconds now includes contention on
runtime-internal locks in addition to sync.Mutex and sync.RWMutex.
* runtime/pprof: Mutex profiles now scale contention by the number of
goroutines blocked on the mutex. This provides a more accurate
representation of the degree to which a mutex is a bottleneck in a Go
program. For instance, if 100 goroutines are blocked on a mutex for 10
milliseconds, a mutex profile will now record 1 second of delay instead of
10 milliseconds of delay.
* runtime/pprof: Mutex profiles also now include contention on runtime-
internal locks in addition to sync.Mutex and sync.RWMutex. Contention on
runtime-internal locks is always reported at
runtime._LostContendedRuntimeLock. A future release will add complete stack
traces in these cases.
* runtime/pprof: CPU profiles on Darwin platforms now contain the process's
memory map, enabling the disassembly view in the pprof tool.
* runtime/trace: The execution tracer has been completely overhauled in this
release, resolving several long-standing issues and paving the way for new
use-cases for execution traces.
* runtime/trace: Execution traces now use the operating system's clock on most
platforms (Windows excluded) so it is possible to correlate them with traces
produced by lower-level components. Execution traces no longer depend on the
reliability of the platform's clock to produce a correct trace. Execution
traces are now partitioned regularly on-the-fly and as a result may be
processed in a streamable way. Execution traces now contain complete
durations for all system calls. Execution traces now contain information
about the operating system threads that goroutines executed on. The latency
impact of starting and stopping execution traces has been dramatically
reduced. Execution traces may now begin or end during the garbage collection
mark phase.
* runtime/trace: To allow Go developers to take advantage of these
improvements, an experimental trace reading package is available at
golang.org/x/exp/trace. Note that this package only works on traces produced
by programs built with go1.22 at the moment. Please try out the package and
provide feedback on the corresponding proposal issue.
* runtime/trace: If you experience any issues with the new execution tracer
implementation, you may switch back to the old implementation by building
your Go program with GOEXPERIMENT=noexectracer2. If you do, please file an
issue, otherwise this option will be removed in a future release.
* slices: The new function Concat concatenates multiple slices.
* slices: Functions that shrink the size of a slice (Delete, DeleteFunc,
Compact, CompactFunc, and Replace) now zero the elements between the new
length and the old length.
* slices: Insert now always panics if the argument i is out of range.
Previously it did not panic in this situation if there were no elements to
be inserted.
* syscall: The syscall package has been frozen since Go 1.4 and was marked as
deprecated in Go 1.11, causing many editors to warn about any use of the
package. However, some non-deprecated functionality requires use of the
syscall package, such as the os/exec.Cmd.SysProcAttr field. To avoid
unnecessary complaints on such code, the syscall package is no longer marked
as deprecated. The package remains frozen to most new functionality, and new
code remains encouraged to use golang.org/x/sys/unix or
golang.org/x/sys/windows where possible.
* syscall: On Linux, the new SysProcAttr.PidFD field allows obtaining a PID FD
when starting a child process via StartProcess or os/exec.
* syscall: On Windows, passing O_SYNC to Open now causes write operations to
go directly to disk, equivalent to O_SYNC on Unix platforms.
* testing/slogtest: The new Run function uses sub-tests to run test cases,
providing finer-grained control.
* Ports: Darwin: On macOS on 64-bit x86 architecture (the darwin/amd64 port),
the Go toolchain now generates position-independent executables (PIE) by
default. Non-PIE binaries can be generated by specifying the -buildmode=exe
build flag. On 64-bit ARM-based macOS (the darwin/arm64 port), the Go

new option defaults to softfloat for version 5 and hardfloat for versions 6
and 7.

results using registers. The linux/loong64 port now supports the address
