* eval.c (ruby_cleanup): $SAFE is turned off in the finalization.

Each END proc should preserve its own $SAFE level. [ruby-core:01119]

* marshal.c (marshal_load): remove unused variable "hash".
  [ruby-core:01120]

* hash.c (env_str_new): freeze strings from ENV. [ruby-talk:72860]

* array.c (rb_ary_first): optional argument to retrieve first n
  elements.

* array.c (rb_ary_last): optional argument to retrieve last n
  elements.
