This file collects notes about what has changed since Go 1.1
|
|
and should be mentioned in the Go 1.2 release notes.
|
|
During the Go 1.2 release process it will be necessary to convert
|
|
it to HTML, similar to go1.1.html, but for now it is a text file,
|
|
to make the process of keeping it up-to-date more lightweight.
|
|
|
|
Please keep the descriptions to a single line, starting with the
|
|
package or cmd/xxx directory name, and ending in a CL number.
|
|
Please keep the list sorted (as in sort.Strings of the lines).
|
|
