  * Kernel
    * extended method:
      * Kernel#warn accepts multiple args in like puts.
    * incompatible changes:
      * system() and exec() closes non-standard file descriptors
        (The default of :close_others option is changed to true by default.)

  * Signal
    * incompatible changes:
      * Signal.trap raises ArgumentError when :SEGV, :BUS, :ILL, :FPE, :VTALRM
        are specified.

  * Time
    * change return value:
      * Time#to_s returned encoding defaults to US-ASCII but automatically
        transcodes to Encoding.default_internal if it is set.

  * Fiber
    * incompatible changes:
      * Fiber#resume cannot resume a fiber which invokes "Fiber#transfer".

* net/imap
  * new methods:
    * Net::IMAP.default_port
    * Net::IMAP.default_imap_port
    * Net::IMAP.default_tls_port
    * Net::IMAP.default_ssl_port
    * Net::IMAP.default_imaps_port

* resolv
  * new methods:
    * Resolv::DNS#timeouts=
    * Resolv::DNS::Config#timeouts=

=== Language changes
=== Compatibility issues (excluding feature bug fixes)

  * Signal.trap

    See above.

  * incompatible changes:
    The :close_others option is true by default for system() and exec().
    Also, the close-on-exec flag is set by default for all new file descriptors.
    This means file descriptors doesn't inherit to spawned process unless
    explicitly requested such as system(..., fd=>fd).
