| Since the last release there has been one large syntactic change to |
| the language, already discussed extensively on this list: semicolons |
| are now implied between statement-ending tokens and newline characters. |
| See http://groups.google.com/group/golang-nuts/t/5ee32b588d10f2e9 for |
| details. |
| |
| By default, gofmt now parses and prints the new lighter weight syntax. |
| To convert programs written in the old syntax, you can use: |
| |
| gofmt -oldparser -w *.go |
| |
| Since everything was being reformatted anyway, we took the opportunity to |
| change the way gofmt does alignment. Now gofmt uses tabs at the start |
| of a line for basic code alignment, but it uses spaces for alignment of |
| interior columns. Thus, in an editor with a fixed-width font, you can |
| choose your own tab size to change the indentation, and no matter what |
| tab size you choose, columns will be aligned properly. |
| |
| |
| In addition to the syntax and formatting changes, there have been many |
| smaller fixes and updates: |
| |
| 6g,8g,5g: many bug fixes, better registerization, |
| build process fix involving mkbuiltin (thanks Yongjian Xu), |
| method expressions for concrete types |
| 8l: support for Windows PE files (thanks Hector Chu) |
| bytes: more efficient Buffer handling |
| bytes, strings: new function Fields (thanks Andrey Mirtchovski) |
| cgo: handling of enums (thanks Moriyoshi Koizumi), |
| handling of structs with bit fields, multiple files (thanks Devon H. O'Dell), |
| installation of .so to non-standard locations |
| crypto/sha256: new package for SHA 256 (thanks Andy Davis) |
| encoding/binary: support for slices of fixed-size values (thanks Maxim Ushakov) |
| exp/vector: experimental alternate vector representation (thanks Jan Mercl) |
| fmt: %p for chan, map, slice types |
| gob: a couple more bug fixes |
| http: support for basic authentication (thanks Ivan Krasin) |
| image/jpeg: basic JPEG decoder |
| math: correct handling of Inf and NaN in Pow (thanks Charles Dorian) |
| misc/bash: completion file for bash (thanks Alex Ray) |

| Since the last release there are two changes to the language: |
| |
| * new builtin copy(dst, src) copies n = min(len(dst), len(src)) |
| elements to dst from src and returns n. It works correctly |
| even if dst and src overlap. bytes.Copy is gone. |
| Convert your programs using: |
| gofmt -w -r 'bytes.Copy(d, s) -> copy(d, s)' *.go |
| |
| * new syntax x[lo:] is shorthand for x[lo:len(x)]. |
| Convert your programs using: |
| gofmt -w -r 'a[b:len(a)] -> a[b:]' *.go |
| |
| In addition, there have been many smaller fixes and updates: |
| |
| * 6g/8g/5g: many bug fixes |
| * 8g: fix 386 floating point stack bug (thanks Charles Dorian) |
| * all.bash: now works even when $GOROOT has spaces (thanks Sergio Luis O. B. Correia), |
| starting to make build work with mingw (thanks Hector Chu), |
| FreeBSD support (thanks Devon O'Dell) |
| * big: much faster on 386. |
| * bytes: new function IndexByte, implemented in assembly |
| new function Runes (thanks Peter Froehlich), |
| performance tuning in bytes.Buffer. |
| * codereview: various bugs fixed |
| * container/vector: New is gone; just declare a Vector instead. |
| call Resize to set len and cap. |
| * cgo: many bug fixes (thanks Eden Li) |
| * crypto: added MD4 (thanks Chris Lennert), |
| added XTEA (thanks Adrian O'Grady). |

| * net: better handling of Close (thanks Devon O'Dell and Christopher Wedgwood) |
| support for UDP broadcast (thanks Jonathan Wills), |
| support for empty packets |
| * rand: top-level functions now safe to call from multiple goroutines |
| (thanks Roger Peppe). |
| * regexp: a few easy optimizations |
| * rpc: better error handling, a few bug fixes |
| * runtime: better signal handling on OS X, malloc fixes, |
| global channel lock is gone. |
| * sync: RWMutex now allows concurrent readers (thanks Péter Szabó) |
