Release calendar:
=== 6.5.30 - Aug 2006 ===
  * The IRIX 6.5.30 release included the following for Guaranteed-Rate
    I/O version 2 (GRIOv2):
    * An extension to the node-level bandwidth allocation, which now
      has two options:
      * The node receives at most (ceiling) the configured bandwidth
      	(previous behavior)
      * The node receives at least (floor) the configured bandwidth
      	(new)
  * The following changes for ggd2:
    * Clarification that the -m option sets per-volume minimum
      distributed bandwidth allocator (DBA)
    * The new -s option, which sets per-node minimum DBA
    * The new -u option, which specifies the DBA update interval

drive type for STK T1000A tape drives, which are supported with APD
release 2.12.

    secure sockets layer (SSL) and secure shell (SSH) is available
    with IRIX 6.5.30. T

Savings Time in accordance with the amendments to the Uniform Time
Act.

nfs(4) protocol used to communicate to nsd(1M).
  * For the IRIX 6.5.30 release, the job limits code was modified to
improve the accuracy of the measurement of shared memory usage within
a job.

=== 6.5.19 - Feb 2003 ===
  * SGI Origin 3900 server
  * F - CXFS
    * A new rolling annual upgrade policy permits you to upgrade from
      6.5.n to the n+1 or n+4 release. This policy is effective with
      6.5.18f.
    * The time required to update and propagate the database across
      nodes in the cluster has been significantly decreased.
    * If you use I/O fencing and ipfilterd(1M) on a node, the
      ipfilterd configuration must allow communication between the
      node and the telnet(1) port on the switch.
    * The CXFS Manager graphical user interface (GUI) has added a new
      icon to represent client-only nodes.
    * Application programmers should be aware that XFS recently
      relaxed the requirement that direct I/O be aligned along
      filesystem block boundaries. As of IRIX 6.5.19f, direct I/O will
      also be accepted using 512-byte alignment. This change makes the
      use of direct I/O on a CXFS partition more consistent with that
      of other vendors requirements and thus makes the use of CXFS
      more transparent.
  *IRIX 6.5.19 provides a Pseudo Random Number Generator, accessible
  through the special files /dev/random, and /dev/urandom. These files
  support the standard file interface operations.

    function was added to libc.
  * OpenSSH version 3.4p1 added
  * Processors can no longer be unisolated while still non-preemptive

    adjusts the cards parameters to maintain good performance across
    very dynamic workloads.
  * Digital Media Environment -64-bit versions of dmedia libraries
    added This release includes 64-bit versions of libaudiofile and
    libcdaudio.
  * Support for sendmail version 8.12.5
=== 6.5.18 - Nov 2002 ===
  * F - CXFS Supports IRIX Client-Only Nodes As of 6.5.18f,
  * F - CXFS relocation disabled; CXFS recovery supported on standby
    nodes In 6.5.18f, CXFS relocation is disabled by default and CXFS
    recovery is supported only when using standby nodes.
  * Support added for UDF filesystems The IRIX 6.5.18 release includes
    read-only support for the UDF filesystems format typically used
    for DVDs and packet-written CD-RWs.
  * QLFC enhanced driver messages QLFC has been enhanced to improve
    its output message format for messages logged to the console and
    SYSLOG.
  * New hinv command support The hinv command with the -v option
    displays the PCI/PCI-X bus speed of QLogic fibrechannel adapters
  * Beginning with IRIX 6.5.18, a user is able to keep the interrupt
    and processing load generated by interval timers away from
    specific CPUs. This feature may reduce latency and jitter for
    real-time applications.
  * Job limits support clarified Job limit values (rlim_t) are 64-bit
    in both n32 and n64 binaries.
  * Enhancements to atcheckpoint() and atrestart() At checkpoint time
    and at restart time, registered functions are called in the same
    order as the first-in-first-out order of their registration with
    atcheckpoint() or atrestart(), respectively.

    2310 and 2342, is updated to version 3.01.07. With this firmware,
    the amber led on the boards will flash when there is no cable
    connected or there is no signal on a connected cable.
  * F - New XVM Manager Graphical User Interface (GUI)
  * F - New XVM snapshot feature
  * F - Support for XVM volumes with FailSafe 2.1.3
  * With IRIX 6.5.17, the underlying documentation tools and books
    have undergone a major upgrade. These processes now allow for SGML
    or XML documents to be published directly into HTML (our delivery
    format). These same tools are available to you as part of the "SGI
    Book Building Tools" product; formerly the "IRIS InSight
    Professional Publisher".
  * The overall behavior of the NFS Version 3 client has been modified
    to improve mixed and heavy load performance.
  * Device drivers now have the capability to create kernel threads
    not associated with particular interrupts to act as daemons and do
    background processing.
  * Support for several new networking interface functions have been
    added. They provide node name and/or a service name translation in
    a protocol-independent manner to support both IPv4 and IPv6.
