They will no longer read or write +unexported struct fields. When marshalling a struct with json or gob the +unexported fields will be silently ignored. Attempting to unmarshal json or +gob data into an unexported field will generate an error. Accessing an +unexported field from a template will cause the Execute function to return +an error. + +Godoc now supports regular expression full text search, and this +functionality is now available on golang.org. + +Other changes: +* arm: initial cut at arm optimizer. +* bytes.Buffer: Fix bug in UnreadByte. +* cgo: export unsafe.Pointer as void*, fix enum const conflict, + output alignment fix (thanks Gustavo Niemeyer). +* crypto/block: mark as deprecated. +* crypto/openpgp: add error and armor. +* crypto: add twofish package (thanks Berengar Lehr). +* doc/spec: remove Maxalign from spec. +* encoding/line: new package for reading lines from an io.Reader. +* go/ast: correct end position for Index and TypeAssert expressions. +* gob: make (en|dec)code(Ui|I)nt methods rather than functions. +* godefs: better handling of enums. +* gofmt: don't attempt certain illegal rewrites, + rewriter matches apply to expressions only. +* goinstall: preliminary support for cgo packages (thanks Gustavo Niemeyer). +* hg: add cgo/_cgo_* to .hgignore. +* http: fix text displayed in Redirect. +* ld: fix exported dynamic symbols on Mach-O, + permit a Mach-O symbol to be exported in the dynamic symbol table. +* log: add methods for exit and panic. +* net: use closesocket api instead of CloseHandle on Windows (thanks Alex Brainman). +* netchan: make fields exported for gob change. +* os: add Sync to *File, wraps syscall.Fsync. +* runtime/cgo: Add callbacks to support SWIG. +* runtime: Restore scheduler stack position if cgo callback panics. +* suffixarray: faster creation algorithm (thanks Eric Eisner). +* syscall: fix mksysnum_linux.sh (thanks Anthony Martin). +* time.NewTicker: panic for intervals <= 0. +* time: add AfterFunc to call a function after a duration (thanks Roger Peppe), + fix tick accuracy when using multiple Tickers (thanks Eoghan Sherry).</pre> + +<h3 id="2011-01-06">2011-01-06</h3> + +<pre> +This release includes several fixes and changes: + +* build: Make.pkg: use installed runtime.h for cgo. +* cgo: disallow use of C.errno. +* crypto/cipher: fix OCFB, + make NewCBCEncrypter return BlockMode. +* doc: 6l: fix documentation of -L flag, + add golanguage.ru to foreign-language doc list, + effective go: explain the effect of repanicking better, + update Effective Go for template API change, + update contribution guidelines to prefix the change description. +* encoding/binary: reject types with implementation-dependent sizes (thanks Patrick Gavlin). +* exp/evalsimple fix handling of slices like s[:2] (thanks Sebastien Binet). +* fmt: made format string handling more efficient, + normalize processing of format string. +* gc: return constant floats for parts of complex constants (thanks Anthony Martin), + rewrite complex /= to l = l / r (thanks Patrick Gavlin), + fix &^=. +* go/ast: provide complete node text range info. +* gob: generate a better error message in one confusing place. +* godoc: fix godoc -src (thanks Icarus Sparry). +* goinstall: add -clean flag (thanks Kyle Lemons), + add checkout concept (thanks Caine Tighe), + fix -u for bzr (thanks Gustavo Niemeyer). +* http: permit empty Reason-Phrase in response Status-Line. +* io: fix Copyn EOF handling. +* net: fix close of Listener (thanks Michael Hoisie). +* regexp: fix performance bug, make anchored searches fail fast, + fix prefix bug. +* runtime/cgo: fix stackguard on FreeBSD/amd64 (thanks Anthony Martin). +* strconv: atof: added 'E' as valid token for exponent (thanks Stefan Nilsson), + update ftoa comment for 'E' and 'G'. +* strings: fix description of FieldsFunc (thanks Roger Peppe). +* syscall: correct Linux Splice definition, + make Access second argument consistently uint32. +</pre> + +<h3 id="2010-12-22">2010-12-22</h3> + +<pre> +A small release this week. The most significant change is that some +outstanding cgo issues were resolved. + +* cgo: handle references to symbols in shared libraries. +* crypto/elliptic: add serialisation and key pair generation. +* crypto/hmac: add HMAC-SHA256 (thanks Anthony Martin). +* crypto/tls: add ECDHE support ("Elliptic Curve Diffie Hellman Ephemeral"), + add support code for generating handshake scripts for testing. +* darwin, freebsd: ignore write failure (during print, panic). +* exp/draw: remove Border function. +* expvar: quote StringFunc output, same as String output. +* hash/crc64: fix typo in Sum. +* ld: allow relocations pointing at ELF .bss symbols, ignore stab symbols. +* misc/cgo/life: fix, add to build. +* regexp: add HasMeta, HasOperator, and String methods to Regexp. +* suffixarray: implemented FindAllIndex regexp search. +* test/bench: update numbers for regex-dna after speedup to regexp. +* time: explain the formats a little better. +</pre> + +<h3 id="2010-12-15">2010-12-15</h3> + +<pre> +Package crypto/cipher has been started, to replace crypto/block. +As part of the changes, rc4.Cipher’s XORKeyStream method signature has changed from + XORKeyStream(buf []byte) +to + XORKeyStream(dst, src []byte) +to implement the cipher.Stream interface. If you use crypto/block, you’ll need +to switch to crypto/cipher once it is complete. + +Package smtp’s StartTLS now takes a *tls.Config argument. + +Package reflect’s ArrayCopy has been renamed to Copy. There are new functions +Append and AppendSlice. + +The print/println bootstrapping functions now write to standard error. +To write to standard output, use fmt.Print[ln]. + +A new tool, govet, has been added to the Go distribution. Govet is a static +checker for Go programs. At the moment, and for the forseeable future, +it only checks arguments to print calls. + +The cgo tool for writing Go bindings for C code has changed so that it no +longer uses stub .so files (like cgo_stdio.so). Cgo-based packages using the +standard Makefiles should build without any changes. Any alternate build +mechanisms will need to be updated. + +The C and Go compilers (6g, 6c, 8g, 8c, 5g, 5c) now align structs according to +the maximum alignment of the fields they contain; previously they aligned +structs to word boundaries. This may break non-cgo-based code that attempts to +mix C and Go. + +NaCl support has been removed. The recent linker changes broke NaCl support +a month ago, and there are no known users of it. +If necessary, the NaCl code can be recovered from the repository history. + +* 5g/8g, 8l, ld, prof: fix output of 32-bit values (thanks Eoghan Sherry). +* [68]l and runtime: GDB support for interfaces and goroutines. +* 6l, 8l: support for linking ELF and Mach-O .o files. +* all: simplify two-variable ranges with unused second variable (thanks Ryan Hitchman). +* arm: updated soft float support. +* codereview: keep quiet when not in use (thanks Eoghan Sherry). +* compress/flate: implement Flush, equivalent to zlib's Z_SYNC_FLUSH. +* crypto/tls: use rand.Reader in cert generation example (thanks Anthony Martin). +* dashboard: fix project tag filter. +* debug/elf, debug/macho: add ImportedLibraries, ImportedSymbols. +* doc/go_mem: goroutine exit is not special. +* event.go: another print glitch from gocheck. +* gc: bug fixes, + syntax error for incomplete chan type (thanks Ryan Hitchman). +* go/ast: fix ast.Walk. +* gob: document the byte count used in the encoding of values, + fix bug sending zero-length top-level slices and maps, + Register should use the original type, not the indirected one. +* godashboard: support submitting projects with non-ascii names (thanks Ryan Hitchman) +* godefs: guard against structs with pad fields +* godoc: added textual search, to enable use -fulltext flag. +* gofmt: simplify "x, _ = range y" to "x = range y". +* gopack: allow ELF/Mach-O objects in .a files without clearing allobj. +* go/token,scanner: fix comments so godoc aligns properly. +* govet: on error continue to the next file (thanks Christopher Wedgwood). +* html: improved parsing. +* http: ServeFile handles Range header for partial requests. +* json: check for invalid UTF-8. +* ld: allow .o files with no symbols, + reading of ELF object files, + reading of Mach-O object files. +* math: change float64 bias constant from 1022 to 1023 (thanks Eoghan Sherry), + rename the MinFloat constant to SmallestNonzeroFloat. +* nm: silently ignore .o files in .a files. +* os: fix test of RemoveAll. +* os/inotify: new package (thanks Balazs Lecz). +* os: make MkdirAll work with symlinks (thanks Ryan Hitchman). +* regexp: speed up by about 30%; also simplify code for brackets. +* runtime/linux/386: set FPU to 64-bit precision. +* runtime: remove paranoid mapping at 0. +* suffixarray: add Bytes function. +* syscall: add network interface constants for linux/386, linux/amd64 (thanks Mikio Hara). +* syscall/windows: restrict access rights param of OpenProcess(), + remove \r and \n from error messages (thanks Alex Brainman). +* test/bench: fixes to timing.sh (thanks Anthony Martin). +* time: fix bug in Ticker: shutdown using channel rather than memory. +* token/position: provide FileSet.File, provide files iterator. +* xml: disallow invalid Unicode code points (thanks Nigel Kerr). +</pre> + +<h3 id="2010-12-08">2010-12-08</h3> + +<pre> +This release includes some package changes. If you use the crypto/tls or +go/parser packages your code may require changes. + +The crypto/tls package's Dial function now takes an additional *Config +argument. Most uses will pass nil to get the same default behavior as before. +See the documentation for details: + http://golang.org/pkg/crypto/tls/#Config + http://golang.org/pkg/crypto/tls/#Dial + +The go/parser package's ParseFile function now takes a *token.FileSet as its +first argument. This is a pointer to a data structure used to store +position information. If you don't care about position information you +can pass "token.NewFileSet()". See the documentation for details: + http://golang.org/pkg/go/parser/#ParseFile + +This release also splits the patent grant text out of the LICENSE file into a +separate PATENTS file and changes it to be more like the WebM grant. +These clarifications were made at the request of the Fedora project. + +Other changes: +* [68]l: generate debug info for builtin structured types, prettyprinting in gdb. +* 8l: add dynimport to import table in Windows PE (thanks Wei Guangjing). +* 8l, runtime: fix Plan 9 386 build (thanks Yuval Pavel Zholkover). +* all: fix broken calls to Printf etc. +* bufio: make Reader.Read implement io.Reader semantics (thanks Roger Peppe). +* build: allow archiver to be specified by HOST_AR (thanks Albert Strasheim). +* bytes: add Buffer.UnreadRune, Buffer.UnreadByte (thanks Roger Peppe). +* crypto/tls: fix build of certificate generation example (thanks Christian Himpel). +* doc/install: describe GOHOSTOS and GOHOSTARCH. +* errchk: accept multiple source files (thanks Eoghan Sherry). +* exec.LookPath: return os.PathError instad of os.ENOENT (thanks Michael Hoisie).. +* flag: fix format error in boolean error report, + handle multiple calls to flag.Parse. +* fmt: add %U format for standard Unicode representation of code point values. +* gc: fix method offsets of anonymous interfaces (thanks Eoghan Sherry), + skip undefined symbols in import . (thanks Eoghan Sherry). +* go/scanner: remove Tokenize - was only used in tests +* gobuilder: add buildroot command-line flag (thanks Devon H. O'Dell). +* html: unescape numeric entities (thanks Ryan Hitchman). +* http: Add EncodeQuery, helper for constructing query strings. +* ld: fix dwarf decoding of 64-bit reflect values (thanks Eoghan Sherry). +* math: improve accuracy of Exp2 (thanks Eoghan Sherry). +* runtime: add Goroutines (thanks Keith Rarick). +* sync: small naming fix for armv5 (thanks Dean Prichard). +* syscall, net: Add Recvmsg and Sendmsg on Linux (thanks Albert Strasheim). +* time: make After use fewer goroutines and host processes (thanks Roger Peppe). +</pre> + +<h3 id="2010-12-02">2010-12-02</h3> + +<pre> +Several package changes in this release may require you to update your code if +you use the bytes, template, or utf8 packages. In all cases, any outdated code +will fail to compile rather than behave erroneously. + +The bytes package has changed. Its Add and AddByte functions have been removed, +as their functionality is provided by the recently-introduced built-in function +“append”. Any code that uses them will need to be changed: +s = bytes.Add(s, b) -> s = append(s, b...) +s = bytes.AddByte(b, c) -> s = append(s, b) +s = bytes.Add(nil, c) -> append([]byte(nil), c) + +The template package has changed. Your code will need to be updated if it calls +the HTMLFormatter or StringFormatter functions, or implements its own formatter +functions. The function signature for formatter types has changed to: + func(wr io.Writer, formatter string, data ...interface{}) +to allow multiple arguments to the formatter. No templates will need updating. +See the change for examples: + http://code.google.com/p/go/source/detail?r=2c2be793120e + +The template change permits the implementation of multi-word variable +instantiation for formatters. Before one could say + {field} +or + {field|formatter} +Now one can also say + {field1 field2 field3} +or + {field1 field2 field3|formatter} +and the fields are passed as successive arguments to the formatter, +by analogy to fmt.Print. + +The utf8 package has changed. The order of EncodeRune’s arguments has been +reversed to satisfy the convention of “destination first”. +Any code that uses EncodeRune will need to be updated. + +Other changes: +* [68]l: correct dwarf location for globals and ranges for arrays. +* big: fix (*Rat) SetFrac64(a, b) when b < 0 (thanks Eoghan Sherry). +* compress/flate: fix typo in comment (thanks Mathieu Lonjaret). +* crypto/elliptic: use a Jacobian transform for better performance. +* doc/code.html: fix reference to "gomake build" (thanks Anschel Schaffer-Cohen). +* doc/roadmap: update gdb status. +* doc/spec: fixed some omissions and type errors. +* doc: some typo fixes (thanks Peter Mundy). +* exp/eval: build fix for parser.ParseFile API change (thanks Anschel Schaffer-Cohen). +* fmt: Scan accepts Inf and NaN, + allow "% X" as well as "% x". +* go/printer: preserve newlines in func parameter lists (thanks Jamie Gennis). +* http: consume request body before next request. +* log: ensure writes are atomic (thanks Roger Peppe). +* path: Windows support for Split (thanks Benny Siegert). +* runtime: fix SysFree to really free memory on Windows (thanks Alex Brainman), + parallel definitions in Go for all C structs. +* sort: avoid overflow in pivot calculation, + reduced stack depth to lg(n) in quickSort (thanks Stefan Nilsson). +* strconv: Atof on Infs and NaNs. +</pre> + +<h3 id="2010-11-23">2010-11-23</h3> + +<pre> +This release includes a backwards-incompatible package change to the +sort.Search function (introduced in the last release). +See the change for details and examples of how you might change your code: + http://code.google.com/p/go/source/detail?r=102866c369 + +* build: automatically #define _64BIT in 6c. +* cgo: print required space after parameter name in wrapper function. +* crypto/cipher: new package to replace crypto/block (thanks Adam Langley). +* crypto/elliptic: new package, implements elliptic curves over prime fields (thanks Adam Langley). +* crypto/x509: policy OID support and fixes (thanks Adam Langley). +* doc: add link to codewalks, + fix recover() documentation (thanks Anschel Schaffer-Cohen), + explain how to write Makefiles for commands. +* exec: enable more tests on windows (thanks Alex Brainman). +* gc: adjustable hash code in typecheck of composite literals + (thanks to vskrap, Andrey Mirtchovski, and Eoghan Sherry). +* gc: better error message for bad type in channel send (thanks Anthony Martin). +* godoc: bug fix in relativePath, + compute search index for all file systems under godoc's observation, + use correct time stamp to indicate accuracy of search result. +* index/suffixarray: use sort.Search. +* net: add ReadFrom and WriteTo windows version (thanks Wei Guangjing). +* reflect: remove unnecessary casts in Get methods. +* rpc: add RegisterName to allow override of default type name. +* runtime: free memory allocated by windows CommandLineToArgv (thanks Alex Brainman). +* sort: simplify Search (thanks Roger Peppe). +* strings: add LastIndexAny (thanks Benny Siegert). +</pre> + +<h3 id="2010-11-10">2010-11-10</h3> + +<pre> +The birthday release includes a new Search capability inside the sort package. +It takes an unusual but very general and easy-to-use approach to searching +arbitrary indexable sorted data. See the documentation for details: + http://golang.org/pkg/sort/#Search + +The ARM port now uses the hardware floating point unit (VFP). It still has a +few bugs, mostly around conversions between unsigned integer and floating-point +values, but it's stabilizing. + +In addition, there have been many smaller fixes and updates: + +* 6l: generate dwarf variable names with disambiguating suffix. +* container/list: make Remove return Value of removed element. + makes it easier to remove first or last item. +* crypto: add cast5 (default PGP cipher), + switch block cipher methods to be destination first. +* crypto/tls: use pool building for certificate checking +* go/ast: change embedded token.Position fields to named fields + (preparation for a different position representation) +* net: provide public access to file descriptors (thanks Keith Rarick) +* os: add Expand function to evaluate environment variables. +* path: add Glob (thanks Benny Siegert) +* runtime: memequal optimization (thanks Graham Miller) + prefix all external symbols with "runtime·" to avoid + conflicts linking with external C libraries. +</pre> + +<h3 id="2010-11-02">2010-11-02</h3> + +<pre> +This release includes a language change: the new built-in function, append. +Append makes growing slices much simpler. See the spec for details: + http://golang.org/doc/go_spec.html#Appending_and_copying_slices + +Other changes: +* 8l: pe generation fixes (thanks Alex Brainman). +* doc: Effective Go: append and a few words about "..." args. +* build: fiddle with make variables. +* codereview: fix sync and download in Python 2.7 (thanks Fazlul Shahriar). +* debug/pe, cgo: add windows support (thanks Wei Guangjing <vcc.163@gmail.com>). +* go/ast: add Inspect function for easy AST inspection w/o a visitor. +* go/printer: do not remove parens around composite literals starting with + a type name in control clauses. +* go/scanner: bug fixes, revisions, and more tests. +* gob: several fixes and documentation updates. +* godoc: bug fix (bug introduced with revision 3ee58453e961). +* gotest: print empty benchmark list in a way that gofmt will leave alone. +* http server: correctly respond with 304 NotModified (thanks Michael Hoisie). +* kate: update list of builtins (thanks Evan Shaw). +* libutf: update to Unicode 5.2.0 to match pkg/unicode (thanks Anthony Martin). +* misc/bbedit: update list of builtins (thanks Anthony Starks). +* misc/vim: update list of builtins. +* mkrunetype: install a Makefile and tweak it slightly so it can be built. +* netchan: fix locking bug. +* pidigits: minor improvements (thanks Evan Shaw). +* rpc: fix client deadlock bug. +* src: use append where appropriate (often instead of vector). +* strings: add Contains helper function (thanks Brad Fitzpatrick). +* syscall: SIO constants for Linux (thanks Albert Strasheim), + Stat(path) on windows (thanks Alex Brainman). +* test/ken/convert.go: add conversion torture test. +* testing: add Benchmark (thanks Roger Peppe). +</pre> + +<h3 id="2010-10-27">2010-10-27</h3> + +<pre> +*** This release changes the encoding used by package gob. + If you store gobs on disk, see below. *** + +The ARM port (5g) now passes all tests. The optimizer is not yet enabled, and +floating point arithmetic is performed entirely in software. Work is underway +to address both of these deficiencies. + +The syntax for arrays, slices, and maps of composite literals has been +simplified. Within a composite literal of array, slice, or map type, elements +that are themselves composite literals may elide the type if it is identical to +the outer literal’s element type. For example, these expressions: + [][]int{[]int{1, 2, 3}, []int{4, 5}} + map[string]Point{“x”: Point{1.5, -3.5}, “y”: Point{0, 0}} +can be simplified to: + [][]int{{1, 2, 3}, {4, 5}} + map[string]Point{“x”: {1.5, -3.5}, “y”: {0, 0}} +Gofmt can make these simplifications mechanically when invoked with the +new -s flag. + +The built-in copy function can now copy bytes from a string value to a []byte. +Code like this (for []byte b and string s): + for i := 0; i < len(s); i++ { + b[i] = s[i] + } +can be rewritten as: + copy(b, s) + +The gob package can now encode and decode interface values containing types +registered ahead of time with the new Register function. These changes required +a backwards-incompatible change to the wire format. Data written with the old +version of the package will not be readable with the new one, and vice versa. +(Steps were made in this change to make sure this doesn’t happen again.) +We don’t know of anyone using gobs to create permanent data, but if you do this +and need help converting, please let us know, and do not update to this release +yet. We will help you convert your data. + +Other changes: +* 5g, 6g, 8g: generate code for string index instead of calling function. +* 5l, 6l, 8l: introduce sub-symbols. +* 6l/8l: global and local variables and type info. +* Make.inc: delete unnecessary -fno-inline flag to quietgcc. +* arm: precise float64 software floating point, bug fixes. +* big: arm assembly, faster software mulWW, divWW. +* build: only print "You need to add foo to PATH" when needed. +* container/list: fix Remove bug and use pointer to self as identifier. +* doc: show page title in browser title bar, + update roadmap. +* encoding/binary: give LittleEndian, BigEndian specific types. +* go/parser: consume auto-inserted semi when calling ParseExpr(). +* gobuilder: pass GOHOSTOS and GOHOSTARCH to build, + write build and benchmarking logs to disk. +* goinstall: display helpful message when encountering a cgo package, + fix test for multiple package names (thanks Fazlul Shahriar). +* gotest: generate correct gofmt-formatted _testmain.go. +* image/png: speed up paletted encoding ~25% (thanks Brad Fitzpatrick). +* misc: update python scripts to specify python2 as python3 is now "python". +* net: fix comment on Dial to mention unix/unixgram. +* rpc: expose Server type to allow multiple RPC Server instances. +* runtime: print unknown types in panic. +* spec: append built-in (not yet implemented). +* src: gofmt -s -w src misc. + update code to use copy-from-string. +* test/bench: update numbers. +* websocket: fix short Read. +</pre> + +<h3 id="2010-10-20">2010-10-20</h3> + +<pre> +This release removes the log package's deprecated functions. +Code that has not been updated to use the new interface will break. +See the previous release notes for details: + http://golang.org/doc/devel/release.html#2010-10-13 + +Also included are major improvements to the linker. It is now faster, +uses less memory, and more parallelizable (but not yet parallel). + +The nntp package has been removed from the standard library. +Its new home is the nntp-go project at Google Code: + http://code.google.com/p/nntp-go +You can install it with goinstall: + goinstall nntp-go.googlecode.com/hg/nntp +And import it in your code like so: + import "nntp-go.googlecode.com/hg/nntp" + +Other changes: +* 6g: avoid too-large immediate constants. +* 8l, runtime: initial support for Plan 9 (thanks Yuval Pavel Zholkover). +* 6l, 8l: more improvements on exporting debug information (DWARF). +* arm: code gen fixes. Most tests now pass, except for floating point code. +* big: add random number generation (thanks Florian Uekermann). +* gc: keep track of real actual type of identifiers, + report that shift must be unsigned integer, + select receive with implicit conversion. +* goplay: fix to run under windows (thanks Yasuhiro Matsumoto). +* http: do not close connection after sending HTTP/1.0 request. +* netchan: add new method Hangup to terminate transmission on a channel. +* os: change TestForkExec so it can run on windows (thanks Yasuhiro Matsumoto). +* runtime: don't let select split stack. +* syscall/arm: correct 64-bit system call arguments. +</pre> + +<h3 id="2010-10-13">2010-10-13</h3> + +<pre> +This release includes changes to the log package, the removal of exp/iterable, +two new tools (gotry and goplay), one small language change, and many other +changes and fixes. If you use the log or iterable packages, you need to make +changes to your code. + +The log package has changed. Loggers now have only one output, and output to +standard error by default. The names have also changed, although the old names +are still supported. They will be deleted in the next release, though, so it +would be good to update now if you can. For most purposes all you need to do +is make these substitutions: + log.Stderr -> log.Println or log.Print + log.Stderrf -> log.Printf + log.Crash -> log.Panicln or log.Panic + log.Crashf -> log.Panicf + log.Exit -> log.Exitln or log.Exit + log.Exitf -> log.Exitf (no change) +Calls to log.New() must drop the second argument. +Also, custom loggers with exit or panic properties will need to be reworked. +For full details, see the change description: + http://code.google.com/p/go/source/detail?r=d8a3c7563d + +The language change is that uses of pointers to interface values no longer +automatically dereference the pointer. A pointer to an interface value is more +often a beginner’s bug than correct code. + +The package exp/iterable has been removed. It was an interesting experiment, +but it encourages writing inefficient code and has outlived its utility. + +The new tools: +* gotry: an exercise in reflection and an unusual tool. Run 'gotry' for details. +* goplay: a stand-alone version of the Go Playground. See misc/goplay. + +Other changes: +* 6l: Mach-O fixes, and fix to work with OS X nm/otool (thanks Jim McGrath). +* [568]a: correct line numbers for statements. +* arm: code generation and runtime fixes, + adjust recover for new reflect.call, + enable 6 more tests after net fix. +* big: fix panic and round correctly in Rat.FloatString (thanks Anthony Martin). +* build: Make.cmd: remove $(OFILES) (thanks Eric Clark), + Make.pkg: remove .so before installing new one, + add GOHOSTOS and GOHOSTARCH environment variables. +* crypto/tls: better error messages for certificate issues, + make SetReadTimeout work. +* doc: add Sydney University video, + add The Expressiveness of Go talk. +* exp/draw/x11: support X11 vendors other than "The X.Org Foundation". +* expvar: add (*Int).Set (thanks Sam Thorogood). +* fmt: add Errorf helper function, + allow %d on []byte. +* gc: O(1) string comparison when lengths differ, + various bug fixes. +* http: return the correct error if a header line is too long. +* image: add image.Tiled type, the Go equivalent of Plan 9's repl bit. +* ld: be less picky about bad line number info. +* misc/cgo/life: fix for new slice rules (thanks Graham Miller). +* net: allow _ in DNS names. +* netchan: export before import when testing, and + zero out request to ensure correct gob decoding. (thanks Roger Peppe). +* os: make tests work on windows (thanks Alex Brainman). +* runtime: bug fix: serialize mcache allocation, + correct iteration of large map values, + faster strequal, memequal (thanks Graham Miller), + fix argument dump in traceback, + fix tiny build. +* smtp: new package (thanks Evan Shaw). +* syscall: add sockaddr_ll support for linux/386, linux/amd64 (thanks Mikio Hara), + add ucred structure for SCM_CREDENTIALS over UNIX sockets. (thanks Albert Strasheim). +* syscall: implement WaitStatus and Wait4() for windows (thanks Wei Guangjing). +* time: add After. +* websocket: enable tests on windows (thanks Alex Brainman). +</pre> + +<h3 id="2010-09-29">2010-09-29</h3> + +<pre> +This release includes some minor language changes and some significant package +changes. You may need to change your code if you use ...T parameters or the +http package. + +The semantics and syntax of forwarding ...T parameters have changed. + func message(f string, s ...interface{}) { fmt.Printf(f, s) } +Here, s has type []interface{} and contains the parameters passed to message. +Before this language change, the compiler recognized when a function call +passed a ... parameter to another ... parameter of the same type, and just +passed it as though it was a list of arguments. But this meant that you +couldn't control whether to pass the slice as a single argument and you +couldn't pass a regular slice as a ... parameter, which can be handy. This +change gives you that control at the cost of a few characters in the call. +If you want the promotion to ..., append ... to the argument: + func message(f string, s ...interface{}) { fmt.Printf(f, s...) } +Without the ..., s would be passed to Printf as a single argument of type +[]interface{}. The bad news is you might need to fix up some of your code, +but the compiler will detect the situation and warn you. + +Also, the http.Handler and http.HandlerFunc types have changed. Where http +handler functions previously accepted an *http.Conn, they now take an interface +type http.ResponseWriter. ResponseWriter implements the same methods as *Conn, +so in most cases the only change required will be changing the type signature +of your handler function's first parameter. See: + http://golang.org/pkg/http/#Handler + +The utf8 package has a new type, String, that provides efficient indexing +into utf8 strings by rune (previously an expensive conversion to []int +was required). See: + http://golang.org/pkg/utf8/#String + +The compiler will now automatically insert a semicolon at the end of a file if +one is not found.
