部分更新内容：
Only targets with public visibility can be bound to something in //external: .
The deprecated -x startup option has been removed.
docker_build: change the repository names embedded by docker_build. You can revert to the old behavior by setting legacy_repository_naming=True.
The string methods strip(), lstrip(), and rstrip() now by default remove the same whitespace characters as Python 3 does, and accept None as an argument.
Deprecated globals HOST_CFG and DATA_CFG are removed. Use strings "host" and "data" instead.
repository_ctx environment is now affected by --action_env flag (value from the client environment will be replaced by value given on the command line through --action_env).
All executable labels must also have a cfg parameter specified.
Removed the cmd_helper.template function. The function was equivalent to: def template(items, template): return [template.format(path = i.path, short_path = i.short_path) for i in items]
