ruby--ruby/ext/socket/mkconstants.rb
k0kubun cc777d09f4 erb.rb: deprecate safe_level of ERB.new 
Also, as it's in the middle of the list of 4 arguments, 3rd and 4th arguments
(trim_mode, eoutvar) are changed to keyword arguments.
Old ways to specify arguments are deprecated and warned now.

bin/erb: deprecate -S option.

We'll remove all of deprecated ones at Ruby 2.7+.

enc/make_encmake.rb: stopped using deprecated interface
