2012-03-28

  1. New append function
  2. Add close function
  3. Update compound literals
  4. Init is now ready to run coroutines
  5. The new type rune is used to represent Unicode code points
  6. New type error
  7. The delete function replaces the previous delete syntax
  8. Map iterations are unpredictable, even on the same machine
  9. Redefined multiple assignmentA, b = 1, 2The specific behavior of
  10. Return Shadowed Value is disabled
  11. Allows copying structs containing unexported fields
  12. Structs and arrays can now be compared and therefore used as map keys; Func can’t be compared; Whether Slice can be compared remains uncertain.

Go to 1.1

2013-05-13

  1. x/0A run-time panic has been changed to a compil-time error.
  2. Methods are introduced
  3. In some cases return can be omitted
  4. Unicode characters with code points greater than 65535 are compatible
  5. When cross-compiling, go disables CGO by default, which can be enabled using the CGO_ENABLED=1 environment variable

Go to 1.2

2013-12-01

  1. Enhanced checking of code that uses nil
  2. New grammarslice = array[2:4:7], 7 indicates the capacity
  3. The scheduler supports pre-emption
  4. Limit the maximum number of threads. Default is 10000
  5. The minimum size of the coroutine stack has been increased from 4KB to 8KB. The maximum size can be set using setMaxStack. The default is 1GB(64bit) / 250MB(32bit).
  6. go doc 被 godoc .replace

Go to 1.3

2014-06-18

  1. The implementation of the stack of coroutines has been modified from fragment model to continuous model. When a coroutine needs a larger stack, it uses a larger block of memory (rather than segments).
  2. There is no longer a fixed order for traversing small maps.

Go to 1.4

2014-12-10

  1. Allows for range syntax:for range x { }
  2. x.M()The type of x is theta**TError reporting (not reported before)
  3. Rewrite runtime with Go (previously C) so GC can detect all active Pointers in the program

Go to 1.5

2015-08-19

  1. Compiler and Runtime are implemented entirely by Go (plus a bit of assembly)
  2. GC supports concurrency, which reduces outage times
  3. GOMAXPROCS defaults to the number of CPU cores, the previous default was 1
  4. Support for internal packages
  5. Support for Vendoring (test characteristics)
  6. Map keys now support abbreviations: 
    m := map[Point]string{{29.935523.52.891566} :"Persepolis".// key does not write Point
    {25.352594.131.034361} :"Uluru",
    {37.422455.122.084306} :"Googleplex",}Copy the code
  7. To supportgo docThe command
