This page summarizes the changes between tagged releases of Go. For full details, see the Mercurial change log.
++This release includes some package changes that may require changes to +client code. + +The Split function in the bytes and strings packages has been changed. +The count argument, which limits the size of the return, previously treated +zero as unbounded. It now treats 0 as 0, and will return an empty slice. +To request unbounded results, use -1 (or some other negative value). +The new Replace functions in bytes and strings share this behavior. +This may require you change your existing code. + +The gob package now allows the transmission of non-struct values at the +top-level. As a result, the rpc and netchan packages have fewer restrictions +on the types they can handle. For example, netchan can now share a chan int. + +The release also includes a Code Walk: "Share Memory By Communicating". +It describes an idiomatic Go program that uses goroutines and channels: + http://golang.org/doc/codewalk/sharemem/ + +There is now a Projects page on the Go Dashboard that lists Go programs, +tools, and libraries: + http://godashboard.appspot.com/project + +Other changes: +* 6a, 6l: bug fixes. +* bytes, strings: add Replace. +* cgo: use slash-free relative paths for .so references. +* cmath: correct IsNaN for argument cmplx(Inf, NaN) (thanks Charles L. Dorian). +* codereview: allow multiple email addresses in CONTRIBUTORS. +* doc/codewalk: add Share Memory By Communicating. +* exp/draw/x11: implement the mapping from keycodes to keysyms. +* fmt: Printf: fix bug in handling of %#v, allow other verbs for slices + Scan: fix handling of EOFs. +* gc: bug fixes and optimizations. +* gob: add DecodeValue and EncodeValue, + add support for complex numbers. +* goinstall: support for Bazaar+Launchpad (thanks Gustavo Niemeyer). +* io/ioutil: add TempFile for Windows (thanks Peter Mundy). +* ld: add -u flag to check safe bits; discard old -u, -x flags. +* math: amd64 versions of Exp and Fabs (thanks Charles L. Dorian). +* misc/vim: always override filetype detection for .go files. +* net: add support for DNS SRV requests (thanks Kirklin McDonald), + initial attempt to implement Windows version (thanks Alex Brainman). +* netchan: allow chan of basic types now that gob can handle such, + eliminate the need for a pointer value in Import and Export. +* os/signal: only catch all signals if os/signal package imported. +* regexp: bug fix: need to track whether match begins with fixed prefix. +* rpc: allow non-struct args and reply (they must still be pointers). +* runtime: bug fixes and reorganization. +* strconv: fix bugs in floating-point and base 2 conversions +* syscall: add syscall_bsd.go to zsycall_freebsd_386.go (thanks Peter Mundy), + add socketpair (thanks Ivan Krasin). +* time: implement time zones for Windows (thanks Alex Brainman). +* x509: support non-self-signed certs. ++
