  note :
    All functions that were defined in parrot/interpreter.h have been renamed in order

    For example, function C<Parrot_new> has been renamed to C<Parrot_interp_new>.

    Also, "Parrot_interp_" has been prepended to all functions that didn't begin with
    "Parrot_" for consistency. For example, function C<allocate_interpreter> has been
    renamed to C<Parrot_interp_allocate_interpreter>.

    Other than the above changes, the below functions were also renamed to make their
    purpose more clear:
        * C<interpinfo> -> C<Parrot_interp_info>
        * C<Parrot_int_get_interp_from_pmc> -> C<Parrot_interp_get_from_pmc>

  note :
    The new rindex_i_s_s and rindex_i_s_s_i opcodes are experimental. They
    duplicate functionality found in the String PMC reverse_index method.

  note :
    The .write_bytes and .read_bytes methods for the Handle PMC (inherited
    by FileHandle and Socket, currently) are new and experimental.

  name : 'Socket.read(nb) with nb > 512'
  eligible : '4.8'
  note :
    The Socket .read method with an nb argument greater than the current SO_RCVBUF buffer size (typically 512) will since 4.8 behave like POSIX read() and recv(), returning only up to nb bytes. You need to loop until the wanted number of bytes is received.

    Will be removed with Release 7.3.0.

  name :  'stricter StringHandle PMC, no auto-reopen, auto-read'
  note:
    StringHandle auto-read and auto-reopen semantics is deprecated. It behaves
    now as the FileHandle PMC.
    Reading from a handle open for writing fails, readall() for a closed handle fails.
    Either use the "rw" mode or the new set_mode() method, and the new seek(0, 0) method.
    Will fail with Release 8.3.0.
