* New in version 16 (1998-12-31):
=================================

  + Hopefully made thing saner w.r.t. handling of large numbers of
    interrupts.

  + Fixed a problem with interrupts on SMP boxen (noted by dth). Note that
    procinfo will only display values for the first CPU.


* New in version 15 (1998-07-04):
=================================

  + Fixed IRQ bug introduced in version 14. Thanks to Samel Vitezslav
    <xsamel00@dcse.fee.vutbr.cz>, and Evgeni A. Nurminski
    <nurmi@ipm.marine.su>.

  + lsdev parses /proc/interrupts properly again. Since I fixed this by
    *simplifying* things I have the lingering suspicion I might have broken
    something somewhere else again, but it seems to work with 2.0.33 and
    2.1.103.  Thanks to Samel Vitezslav for letting me know.


* New in version 14 (1998-05-24):
=================================

  + Forgot to freopen stdin and stderr as well as stdout when using -F,
    leading to funny things in full-screen mode. Fixed.

  + Appearantly there are some SMP motherboard out there that can handle 24
    IRQ's instead of 16. Fixed, and also to make sure that things still fit
    inside 80x24, procinfo now squeezes the IRQ list by default. The -i
    option now unsqueezes the display. (Thank you Edwin Huffstutler
    <edwinh@computer.org>.)


* New in version 13 (1998-03-07):
=================================

  + Procinfo's gone interactive! :-) Pressing 'q' when running full-screen
    exits, pressing 'd' toggles between what the -d option does, etc. etc.
    etc. etc. etc.

  + Fixes for Linux/Alpha, relating to the obscene number of IRQ's on that
    platform. To make it possible to keep running procinfo full-screen on a
    80x24 terminal on Alphas, I've added an option -i that squeezes the IRQ
    portion of the display by only printing IRQ's that have either a label
    or a non-zero interrupt count. It's not guaranteed to work if you really
    *have* a lot of IRQ's allocated, of course, but you can't have
    everything.

  + Fixed a not-zero-terminated bug and a driver-name-starts-with-digit bug,
    both in the interrupts handling, both thanks to Johan Lindh
    <sirreal@warrior.net>.

  + Added a short manpage for socklist.

  + Signal handling cleaned up. This incidentally fixes a bug with
    suspending a procinfo compiled with glibc2, which I had brilliantly
    predicted way back when I wrote version 0.1 in 1994, long before I'd
    even *heard* of glibc2. Clever, huh?


* New in version 12 (1998-01-21):
=================================

  + New utility! Written by Larry Doolittle <ldoolitt@jlab.org>. Socklist
    gives you a list of all open sockets, enumerating types, port, inode,
    uid, pid, fd and the program to which it belongs. Thanks Larry!

  + With -d or -D and update intervals other than one second, the values
    displayed are once more the numbers of IRQ ticks, etc. per interval,
    rather than averaged out per second. To get the old behaviour back, use
    the new -S option.

  + Bugfixes for Alphas (Thomas Bogendoerfer <tsbogend@alpha.franken.de>).

  + Forgot to keep the modules stuff compatible with 2.0.x. Thank you
    <soneill@netaxs.com> and Marty Leisner <leisner@sdsp.mc.xerox.com>.

  + Yet more make_version tweaks in order to survive the advent of egcs.

  + Should survive (not necessarily prettily) impossible values from /proc
    when jiffies wraparound has occurred, and, incredibly, still work on SMP
    boxen as well. Please report if any bugs remain. Thanks to Jon Lewis
    <jlewis@inorganic5.fdt.net>.

  + New non-numerical entries in /proc/interrupts (NMI, IPI) could cause
    confusion (J. Alan Eldridge <alane@wozzle.dialup.access.net>).

  + Only require $TERM if really necessary. This makes `rsh <host> procinfo'
    work.

  + Dropped the "0." from the version number. I mean, what's the point?

  + Fixed /proc/interrupts breakage with 2.1.80. For simplicity's sake I've
    dropped the '+' indicating a fast irq handler -- it's not there in
    2.1.80 anyway.


* New in version 0.11 (1997-05-28):
===================================

  + Memory usage won't break on 2.1.41 and later.

  + The status line should be able to deal better with kernels
    compiled with gcc snapshots, i.e. where /proc/version has
    something like "(gcc driver version x snapshot y executing gcc
    version z)". I don't know if the current code can live with all
    variations on this theme though.

  + The occasional bug fix I've forgotten about by now.


* New in version 0.10 (1996-09-15):
===================================

  + Made parsing of /proc/interrupts a bit more flexible (its format
    changed a little in late 2.0.x kernels).

  + Now runs if you don't have module support compiled in. Thanks both
    to Rob Hooft <Rob.Hooft@EMBL-Heidelberg.de> and Andrew Pam
    <avatar@glasswings.com.au> for pointing this one out.

  + Buglet in make_version() fixed.

  + Very silly buglet with IRQ labels fixed (thanks to Harald Anlauf
    <anlauf@crunch.ikp.physik.th-darmstadt.de>).


* New in version 0.9 (1996-04-28):
==================================

  + Fixed a problem with memory info not getting updated.

  + Fixed a problem with include files for recent versions of libc.

  + Added lsdev, a proglet that combines IRQ, DMA and I/O port
    information into one list. (There wasn't room left on the screen
    for I/O ports in procinfo itself, hence this perl script.) Note
    that this doesn't always work because some drivers use different
    labels in different files for the same hardware.

  + The header line should now always fit on one screen line -- run
    procinfo in an xterm, resize its width a few time and see the
    magic! :-) It defaults to 80 characters if stdout isn't a
    terminal.


* New in version 0.8 (1996-01-05):
==================================

  + If your kernel has /proc/cmdline, its contents are printed with
    `-a' or `-m'.

  + Support for the cached field in /proc/meminfo.



[NOTE: any mention of kernel patches down below is obsolete for current kernels.]


* New in version 0.7 (1995-11-22):
==================================

  + Thanks to Marcel J.E. Mol <marcel@duteca.et.tudelft.nl> we now
    have the following:

      - Disk info is now split in read and write io's, if you run Linux
        1.3.43 or later or if you apply pre-1.3.43-disk_io_blk.patch to
	the kernel.

      - The update interval is now more accurate (wow, one of the TODO
	entries is gone:-).

      - Fixed usage message (-F).

    I added another switch -b to procinfo. Assuming you have applied
    the patch mentioned above, the disk read and write figures are for
    blocks transferred with -b, or for number of requests without it.
    I'd have done it the other way 'round, were it not for backwards
    combatability.

  + Both utilities now accept a decimal fraction with the -n option.


* New in version 0.6 (1994-11-01):
==================================

  + If your kernel is 1.1.48 or later, the IRQ display tells you
    which DMA channels are used by what.

  + Explanation of page in/out in the manual page corrected. Thanks
    to Henry Ware <hware@bronze.coil.com>.

  + Support added for terminals with magic cookies (yes I know it's
    1994). See the COOKIE_NOSOSE define in procinfo.c if you're
    suffering from this.

  + New option -F followed by a file or device name causes all output
    to go to that file or device. Useful if you want to nohup procinfo
    with the output going to a tty. Based on a patch by Steven Lembark.


* New in version 0.5 (1994-08-12):
==================================

  + The hostname is displayed in the top right corner (as suggested
    by Danny ter Haar). I cut off half of the /proc/version line as
    it was getting far too long in recent kernel versions to fit on
    one line.

  + Times larger than 24 hours are now displayed as `days hh:mm:ss.ss'
    Patch from The Big Cheese <root@delphi.glendon.yorku.ca>.

  + New option `-D' to show totals on memory usage and differences
    on the rest. Patch from Steven Lembark <lembark@wrkhors.la.ca.us>.

  + If your kernel is 1.1.43 or later, you also get the names of who
    is using the irq channels appearing and disappearing as drivers
    grab and release irq's.


* New in version 0.4 (1994-05-21):
==================================

  + The CPU times display was rather buggy. This has been fixed and
    improved to display 100th of seconds. Thanks to Rob Janssen for
    the patches.

  + The various #define's have gone. procinfo now displays whatever
    info is available. Note that info from /proc/net is still
    missing, since I don't have the network code compiled into my
    kernel.

  + Thanks again to Rob Janssen, procinfo should now run correctly
    with older versions of the shared libraries.

  + Modules which are deleted or uninitialized and file systems
    which require no device are now marked as such.


* New in version 0.3 (1994-05-08):
==================================

  + Interrupts look better. Idea from Danny ter Haar
    <danny@cistron.nl.mugnet.org>.

  + A new option `-d' gives you the differences for memory,
    pagein/out, swapin/out, disks, context and interrupts since last
    update. Suggested by Rob Janssen <pe1chl@rabo.nl>.

  + Since the advent of /proc/devices in Linux 1.1.3 and of the
    modularized SLS 1.0.5 kernel means that not everything will fit on
    one 80x25 screen anymore, I have introduced a new option `-m' that
    will replace the default screen with one showing all modules (and
    devices and filesystems if your kernel is new enough). The modules
    list has disappeared from the default display. `-a' gives you
    everything.

  + Added percentages for CPU usage. Note that these are accumulated
    percentages, as opposed to those given by top(1).

  + To accommodate both those who use 1.0.x kernels and those who use
    1.1.x kernels, I have re-arranged the #defines a bit. See below.


* New in version 0.2 (1994-03-30):
==================================

  + The kernel patch broke rpc.rstatd. Fixed. Please make sure you
    don't use an old version of procinfo with the new kernel patch or
    vice versa.

  + Wildly expanded manual page.

  + A few cosmetic changes.


  + Semi-obsolete interrupt patch.
  ================================

  As is, the `intr' line in /proc/stat under Linux 1.0 prints the
  accumulated number of interrupts that have happened since boot-up
  for all 16 irq channels lumped together. You can change this to
  display the number of interrupts for each individual irq by applying
  the patch in `kernel.patch' to the kernel sources (if necessary) and
  then compiling procinfo with -DHAVE_IRQ_ARRAY.

  If your kernel is at version 1.0.4 or older, just say

  cd /usr/src/linux		(or whichever dir contains the kernel sources)
  patch < kernel.patch

  If you have version 1.0.5, then the patch is already part of the
  standard kernel, except that there is a small bug in
  linux/fs/proc/array.c at line 101 where it reads

		"%u",

  but should read

		"intr %u",

  Change this by hand and recompile and you should be all set.

  As said above, the patch that came with procinfo 0.1 broke the
  rpc.rstatd daemon which reads the first number form the `intr' line
  and assumes that that line contains the total number of interrupts.
  In this version of procinfo, the patch merely adds the sixteen extra
  numbers *after* the original total number (rather than replacing the
  total number *with* the sixteen extra numbers), thus retaining
  compatibility with rpc.rstatd.
