|Files in this directory are data for Go's API checker ("go tool api", in src/cmd/api).
|Each file is a list of API features, one per line.
|go1.txt (and similarly named files) are frozen once a version has been
|shipped. Each file adds new lines but does not remove any.
|except.txt lists features that may disappear without breaking true
|next.txt is the only file intended to be mutated. It's a list of
|features that may be added to the next version. It only affects
|warning output from the go api tool.
