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). cmd/5a: removed support for R9/R10 (use m/g instead) (CL 9840043). cmd/cgo, cmd/go: support including C++ code with cgo (CL 8248043). fmt: indexed access to arguments in Printf etc. (CL 9680043). go/build: support including C++ code with cgo (CL 8248043). io: Copy prioritizes WriterTo over ReaderFrom (CL 9462044). testing: AllocsPerRun is now quantized to an integer (the type is still float64) (CL 9837049).
