=== kgio 2.2.0 - kinder, gentler I/O for the Internets / 2011-02-04 03:07 UTC

  * sockets accept()ed by a TCP_NOPUSH/TCP_CORK listener
    automatically flush on kgio_*read calls if there is pending
    data.  "Kgio.autopush = false" disables this globally,
    and Kgio::Socket also get "kgio_autopush=" to enable/disable
    on a per-object individual basis.

  * ECONNRESET exceptions get empty backtraces for kgio_*read.
    There's nothing a programmer can do about these, so there's
    no point in going through the expensive backtrace generation
    process.

  * Kgio.try* singleton methods added for working with non-Kgio
    enhanced objects.  No more needing to use Object#extend
    and blowing away your method cache to make existing I/O
    objects kinder and gentler.

  * IPv6 support should be complete, systems without a native
    getaddrinfo(3) are now unsupported (and will remain so
    unless somebody complains).

  There should be no other backwards-incompatible changes other
  than requiring getaddrinfo(3) and friends for IPv6 support.
