There are still a few minor documentation issues to resolve, +and a handful of bugs that should be addressed before the release, but the vast +majority of Go programs should be completely unaffected by any changes we make +between now and the full release. + +If you're interested in helping us test, eager to try out Go 1, or just +curious, this weekly snapshot is the one to try. We'll issue a new App Engine +Go 1 beta SDK very soon, so if you're an App Engine user you can try it there +too. + +To help us focus on any remaining bugs and avoid introducing new ones, we will +restrict our attention to critical fixes and issues marked Go1-Must in the +issue tracker. Everything non-essential will be held until after the Go 1 +release is cut and in the field for a while. + +Changes in this snapshot: +* archive/zip: verify CRC32s in non-streamed files, + write data descriptor signature for OS X; fix bugs reading it. +* build: build correct cmd/dist matching GOHOSTARCH (thanks Shenghou Ma), + re-enable some broken tests in run.bash (thanks Shenghou Ma), + remove some references to Make.inc etc. + use run.go for running tests. +* builder: use short test for subrepos (thanks Shenghou Ma). +* cgo, runtime: diagnose callback on non-Go thread. +* cmd/api: set compiler for all build contexts, + work on Windows again, and make gccgo files work a bit more. +* cmd/cgo: document CGO_LDFLAGS and CGO_CFLAGS, + silence const warnings. +* cmd/dist, cmd/go: move CGO_ENABLED from 'go tool dist env' to 'go env' (thanks Shenghou Ma). +* cmd/dist: fix build for Linux/ARM (thanks Shenghou Ma), + use correct hg tag for go version (thanks Alex Brainman). +* cmd/fix: add rules for net/http -> net/http/httputil renames. +* cmd/gc: allow ~ in import paths, + delete old map delete in walk, + do not confuse unexported methods of same name, + if $GOROOT_FINAL is set, rewrite file names in object files, + implement len(array) / cap(array) rule, + import path cannot start with slash on Windows (thanks Shenghou Ma), + must not inline panic, recover, + show duplicate key in error, + unnamed struct types can have methods. +* cmd/go: add -compiler, + add env command, use to fix misc/cgo/testso, + allow go get with arbitrary URLs, + allow ssh tunnelled bzr, git and svn (thanks Ingo Oeser), + always provide .exe suffix on windows (thanks Shenghou Ma), + document import path meta tag discovery in go help remote, + honor buildflags in run, test (thanks Rémy Oudompheng), + local import fixes, + make go get new.code/... work, + rebuild external test package dependencies, + respect $GOBIN always, + support -compiler for go list, fix isStale for gccgo (thanks Rémy Oudompheng). +* cmd/godoc: add support for serving templates. + fix codewalk handler (thanks Francisco Souza). + remove extra / in paths (thanks Ugorji Nwoke), + support $GOPATH, simplify file system code, + switch on +1 buttons. +* cmd/gofmt: fix race in long test (thanks Mikio Hara). +* codereview: fix for Mercurial 2.1. +* crypto/x509: allow server gated crypto in windows systemVerify (thanks Mikkel Krautz), + do not forget to free cert context (thanks Alex Brainman), + don't include empty additional primes in PKCS#1 private key, + enforce path length constraint, + new home for root fetchers; build chains using Windows API (thanks Mikkel Krautz). +* csv: clarify what a negative FieldsPerRecord means. +* database/sql: add docs about connection state, pooling, + ensure Stmts are correctly closed (thanks Gwenael Treguier), + fix double connection free on Stmt.Query error, + fix typo bug resulting in double-Prepare. +* database/sql: add ErrBadConn. +* doc/go1: template packages have changed since r60. +* doc/go_mem: init-created goroutine behavior changes for Go 1 (thanks Shenghou Ma). +* doc/gopher: flip frontpage gopher's eyes. +* doc: add "About the go command" article, + add C?
