| <h3 id="2010-03-30">2010-03-30</h3> |
| |
| <pre> |
| This release contains three language changes: |
| |
| 1. Accessing a non-existent key in a map is no longer a run-time error. |
| It now evaluates to the zero value for that type. For example: |
| x := myMap[i] is now equivalent to: x, _ := myMap[i] |
| |
| 2. It is now legal to take the address of a function's return value. |
| The return values are copied back to the caller only after deferred |
| functions have run. |
| |
| 3. The functions panic and recover, intended for reporting and recovering from |
| failure, have been added to the spec: |
| http://golang.org/doc/go_spec.html#Handling_panics |
| In a related change, panicln is gone, and panic is now a single-argument |
| function. Panic and recover are recognized by the gc compilers but the new |
| behavior is not yet implemented. |
| |
| The ARM build is broken in this release; ARM users should stay at release.2010-03-22. |
| |
| Other changes: |
| * bytes, strings: add IndexAny. |
| * cc/ld: Add support for #pragma dynexport, |
| Rename dynld to dynimport throughout. Cgo users will need to rerun cgo. |

| * flag: add user-defined flag types. |
| * gc: usual bug fixes |
| * go/ast: generalized ast filtering. |
| * go/printer: avoid reflect in print. |
| * godefs: fix handling of negative constants. |
| * godoc: export pprof debug information, exported variables, |
| support for filtering of command-line output in -src mode, |
| use http GET for remote search instead of rpc. |
| * gofmt: don't convert multi-line functions into one-liners, |
| preserve newlines in multiline selector expressions (thanks Risto Jaakko Saarelma). |
| * goinstall: include command name in error reporting (thanks Andrey Mirtchovski) |
| * http: add HandleFunc as shortcut to Handle(path, HandlerFunc(func)) |
| * make: use actual dependency for install |
| * math: add J1, Y1, Jn, Yn, J0, Y0 (Bessel functions) (thanks Charles L. Dorian) |

| <h3 id="2010-03-04">2010-03-04</h3> |
| |
| <pre> |
| There is one language change: the ability to convert a string to []byte or |
| []int. This deprecates the strings.Bytes and strings.Runes functions. |
| You can convert your existing sources using these gofmt commands: |
| gofmt -r 'strings.Bytes(x) -> []byte(x)' -w file-or-directory-list |
| gofmt -r 'strings.Runes(x) -> []int(x)' -w file-or-directory-list |
| After running these you might need to delete unused imports of the "strings" |
| package. |
| |
| Other changes and fixes: |
| * 6l/8l/5l: add -r option |
| * 8g: make a[byte(x)] truncate x |

| <h3 id="2010-01-27">2010-01-27</h3> |
| |
| <pre> |
| There are two small language changes: the meaning of chan <- chan int |
| is now defined, and functions returning functions do not need to |
| parenthesize the result type. |
| |
| There is one significant implementation change: the compilers can |
| handle multiple packages using the same name in a single binary. |
| In the gc compilers, this comes at the cost of ensuring that you |
| always import a particular package using a consistent import path. |
| In the gccgo compiler, the cost is that you must use the -fgo-prefix |
| flag to pass a unique prefix (like the eventual import path). |
| |
| 5a/6a/8a: avoid use of fixed-size buffers (thanks Dean Prichard) |

| |
| <h3 id="2009-12-22">2009-12-22</h3> |
| |
| <pre> |
| 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) |

| handling of structs with bit fields, multiple files (thanks Devon H. O'Dell), |
| installation of .so to non-standard locations |

| 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 |

| Since the last release there are two changes to the language: |
| |

| gofmt -w -r 'bytes.Copy(d, s) -> copy(d, s)' *.go |
| |
