+
+pcp-3.8.2 (31 July 2013)
+    - Support for the Unix domain socket transport between pmcd
+      and client tools, using the "unix:" host specifier (and the
+      more forgiving "local:" which falls back to localhost if no
+      platform support exists).
+    - Note: PCP_RUN_DIR is as a result now installed owned by the
+      "pcp" user and group (rather than as "root").  Several other
+      directories are also now installed "pcp"-owned too, after
+      (unrelated) pmie and changes described below.
+    - Support for automatic extraction of client tool credentials
+      with Unix domain sockets, and transfer to interested PMDAs,
+      on Linux, Mac OS X and Solaris.  IOWs, PMDAs now know which
+      user they are acting on behalf of for each connection, when
+      this class of socket is used.  In a future release, it hoped
+      to make this the default local connection style.
+    - Extensions to pmdaproc to allow it to perform access-control
+      checking and metric value fetches as the user requesting the
+      data, instead of as root, such that kernel-based permission
+      checking is now performed.
+    - Re-enabled pmdaproc by default on Linux.
+    - pmdagfs2: updates to metrics, tests and a new manual page.
+    - pmdagfs2: fixes for distributions without gfs2 trace-points.
+    - pmdalinux: fix hinv.map.lvname realink memory corruption bug.
+    - pmdalinux: fix issue where EPERM passed out as a fetch result
+      with inaccessible filesystem paths.
+    - pmdalinux: rework /proc/net/snmp metric extraction, added new
+      metrics from recent kernels (checksum error counters, icmpmsg).
+    - Linux PMDA SNMP metric type migration support (log rewriter).
+    - pmdasystemd: correct .maxmem metric to PM_SPACE_BYTE

+    - PMDA_INTERFACE_4 and the support of dynamic subtrees of the PMNS
+      where the PMDA (not PMCD) maintains knowledge of the PMNS.
+    - RPM packaging split into pcp, pcp-libs and pcp-libs-devel
+      pcp-libs is common - it's required by pcp and by pcp-libs-devel but
+      pcp and pcp-libs-devel can be installed with or without each other.
+    - Added separate specific licenses for the new subpackages,
+      particularly pcp-libs, which is LGPL.

+    - Don't ship static libraries in Fedora, we have the debug package for that
+    - Install .NeedRebuild, add to %files and remove crud from %post scriptlets
+    - Added %changelog in RPM spec and moved %files to end before %changelog
+    - Move demos, examples and demo PMDAS to the libs-devel package since they
+      are not used for production (but are useful for devel and needed for QA).
+    - Don't install trace demo binaries since src is installed anyway
+    - Reconciled build/rpm/pcp.spec.in with build/rpm/pcp_fedora.spec
+    - Integrated RPM packaging support for perl-PCP-PMDA and perl-PCP-MMV
+      (but perl-PCP-Logsummary is not currently shipped in RPM packages)
+    - RPM build requires perl(ExtUtils::MakeMaker) rather than
+      perl-extutils-makemaker (this is the standard notation)
+    - For easier upgrades, the perl PMDAs only really require pcp >= package
+      version (until we change or extend an API).
+    - ReplacePmnsSubtree fix bad signal handling botch (affecting MMV PMDA)

+pcp-2.2.1-3 (21 June 2001)
+    - remove unwanted *.rpmorig files after upgrade 
+    - fixed bug #827972, pcp root exploit with pmpost
+    - fixed assorted other security issues.
+
+pcp-2.2.0-15 (23 May 2001)
+    - don't include linux/kernel_stat.h and avoid __sparc__ conditional code 
+    - from Michal Kara: rc will rebuild PMNS if root_* files newer than root
+    - add the roomtemp PMDA for measuring temperatures using the 1-Wire
+      serial network ans sensor technology from Dallas Semiconductor
+    - zero network.tcpconn values before counting them in /proc/net/tcp
+      (Michal Kara's original code was correct - markgw busted it!)
+    - add new LGPL library libpcp_http. Used by permission of the author,
+      Laurent Demailly <L@Demailly.com>
+    - minor surgery on apache PMDA to link with -lpcp_http
+    - minor fix diagnostic from __pmLogRead
+    - as reported by Alexander L. Belikoff <abel@vallinor4.com>, it was
+      not possible to disable the primary logger via changes to the
+      /var/pcp/config/pmlogger/control file ... this has been fixed
+    - as reported by Alan Bailey <bailey@mcs.anl.gov>, the assumption
+      that /var/pcp/config/pmlogger/control was version 1.1 was implicit 
+      ... this is now documented and the pmlogger_* scripts will warn
+      if the deprecated version 1.0 format is used accidently
+    - from Michal Kara: fix mem leak in apache PMDA
+    - from Michal Kara: install /var/pcp/config/pmlogger/Makefile
+      (src is in src/pmlogctl/Makefile.install). This provides pre-processing
+      of pmlogger config files with cpp.
+    - reintroduction of "impl.h" header, deprecate "pmapi_dev.h" and major
+      makefile surgery to reintegrate the IRIX and Linux PCP source trees
+    - add ia64 support infrastructure.
+    - use -fno-strict-aliasing for correct ia64 compilation
+    - use -fpic to avoid gprel errors linking shlibs on ia64

+    - promote shping to open-source status
+    - fix bug #814989 where disk.all.* not summed correctly (if the sard
+      patch has been applied to running kernel)
+    - with the sard patch applied to the kernel, disk.all metrics were
+      being summed as the total of disk.partitions and disk.dev metrics,
+      resulting in approximately twice the rate of disk I/O for the
+      disk.all metrics
+    - added more disk metrics and update help text
+    - the "cpu" instance domain is now dynamic and supports any number of CPUs
+    - fixed pmie rc and pmie_{check,daily} scripts
+    - a bunch of places were using $PCP_VAR_DIR/config/pmcd/pmcd.conf
+      as the path to pmcd.conf (which is correct). Others were using
+      /etc/pmcd.conf (which is only correct on IRIX).
+    - merged IRIX/Linux versions of pmsocks
+    - mimic the IRIX xconfirm behaviour more closely, pv 817289
+    - pv:817367 Handle SIGCHLD from xconfirm problem on Linux
+    - minor changes in error messages to make them less IRIX-centric
+      and hence more sensible for Linux
+    - fix weblog link in doc dir logic and old netscape should be
+      detected as CERN not NS_PROXY.
+    - fix weblog so regex in the configuration file is recognized
+      correctly on all platforms
+    - only run weblogconv.sh on linux
+    - conversion to more simple copyright in numerous places
+    - avoid grep -q usage: not supported on early IRIX
+    - pv:803341 Change Creator: for mkaf from mkaf to pmchart to assist
+      with pmafm replay when pcp also installed.
+    - updated man page text for platform-agnostic descriptions.
+    - fix 817880 pmafm remove does not list all files
+    - src/pmie/GNUmakefile Fix busted sed translation of the control
+      file so the logfiles (and hence directories) are ...pmie/<hostname>
+      rather than pmie<hostname>
+    - renamed all Makefiles to GNUmakefile
+    - makefile surgery to allow multiple RPMs to be built from one src tree
+    - fixes to src/pmcd/pmdaproc.sh to not use test -e
+    - pv:815326 fix pcp linux /usr/share/magic doesn't detect pmie config
+    - pv:818381 fix pmie_check fails esp integration
+    - man page for pmlogsummary was in both pcp and pcp-pro
+    - fix to src/pmie/pmie_check.sh, improve pattern to match No such
+      file or directory for linux
+    - fix all linux specs to install root,root rather than root,bin
+      (needed to avoid warnings when installing on redhat7.1)
+    - add GNUmakefile.install for all PMDAs, installed in each PMDA dir
+    - fix src/pmdas/weblog/server.sh to use quotes on -d that was breaking
+      when parameter empty.
+    - pv:807561 change pmprobe -i and -I semantics to call pmGetInDom
+      rather than using the returned indom from pmFetch
+    - add hinv.machine for oview to use
+    - change the cpu instance domain to use the numa names if they are
+      present on the machine, else revert to cpuX syntax
+    - numerous fixes so the src RPM builds on all platforms
+    - pv:824382 - xfs block metrics were scaled incorrectly
+    - add support for /proc/slabinfo metrics (mem.slabinfo.*)
+    - add new "process" and "mounts" PMDAs, contributed by Alan Baily
+    - added GPL copyrights to process and mounts src, fixed makefiles
+      to extract domain number from stdpmid and added install targets,
+      and small change to ignore comments in conf files.
+    - added hinv.pagesize (uses the getpagesize(2) system call)
+    - fixed bug #825229 where rpm upgrade would clobber root pmns for PMDAs
+
+pcp-2.1.10-8 (released circa Oct 18 2000, with SGI ACE1.4)
+    - guard against DOS attack by restring incoming PDU size to 64K.
+    - add hinv.map.cpu and hinv.cpu metrics exported by /proc/cpuinfo
+    - fix small error in INSTALL_MAN rule in src/include/builddefs.in
+    - fix for bug #793427 - correct symlinks for man pages with multiple
+      entries in the .SH NAME section.
+    - add network.tcpconn metrics to export counts of tcp connections in each
+      state. Code contributed by Michal Kara (lemming@arthur.plbohnice.cz)
+    - few minor fixes for build on ia64
+
+pcp-2.1.9-12 (released circa Sept 13 2000, with SGI Propack1.4)
+    - for 2.4 without sard, correctly match disk numbers in /proc/stat
+      with major,minor numbers in /proc/partitions.
+
+pcp-2.1.9-11 (unreleased)
+    - add pagebuf metrics (Daniel and Nathan)
+    - fixes so the build works if pcp is not already installed
+    - minor security fix to pcp.spec.in (force mode 644 for .NeedRebuild)
+    - make sure the src RPM builds correctly (LSRCFILE issues from LinuxWorld)
+    - fix for bug #797756, upgrade from pcp2.1.6 to any newer version leaves
+      pcp chkconfig off and the name space does not get rebuilt.
+    - extended the weblogs PCP agent so it can report proxy/squid
+      http servers, and added assorted http cache statistics.
+    - fixed the Cisco router PCP agent (it was broken in pp1.3).
+    - add support for disk stats in 2.4.x kernels with "disk_io" field
+      in /proc/stat (only used when sard patch is not installed)
+    - if the pcp-pro package (SGI proprietary) is installed, all libpcp
+      clients on linux are now "authorized" to monitor IRIX systems that
+      do not have a pmcd collector license.
+
+pcp-2.1.9-6 (released 2 Aug 2000 for propack1.4 - alpha, not final)
+    - install /usr/share/pcp/lib/rc-proc.sh containing common
+      shell functions for use by rc scripts - these functions
+      are tolerant of the chkconfig command missing (as in SUSE).
+    - update all rc scripts and {pmlogger,pmie}_{check,daily} scripts
+      to use the new rc-proc.sh functions. Remove the /etc/sysconfig
+      stuff entirely (it was not being used anyway).
+    - fix for #795934 : after rpm -U, pcp is chkconfig off. It turned
+      out that an upgrade executes the %post _and_ the %preun scripts,
+      which resulted in pcp being chkconfig'd on then off again.
+    - fix pmie rc scripts so they work, are chkconfig friendly,
+      and cope with _and_ without pmieconf (which is in pcp-pro).
+      Also install /var/pcp/config/pmie/config.default as a simple example
+      to monitor the load average and report to syslog. The pmie
+      daemon is chkconfig off by default.
+    - default run levels for pmcd and pmie (daemon) are now 2345, for SUSE
+    - reconcile troff and groff differences in man page sources
+    - fix for bug #797049 use strftime(%z) to determine timezone offsets
+      w.r.t. daylight savings
+    - portability surgery on src/libpcp_trace, and add new pmtracecounter()
+      function, see pmtracebegin(3) for details.
+    - reconcile pcp.env and pmcd.options from IRIX
+    - fix for bug #797048 update-magic does not fully remove old entries
+      before adding new, hence the magic file would grow after each upgrade
+    - other minor reconciliation work with IRIX
+    - fix build environment to allow proper handling of compressed man pages
+    - add support for RPM version 4.
+    - add support for add kernel.{all,percpu}.syscall metrics
+      (requires kernel patch)
+    - fixed for bug #797164: potential SEGV due to calling realloc on a 
+      misused pointer - src/pmdas/weblog/weblog.c
+    - use realpath(3) to resolve devices in /proc/mounts for filesys.* metrics
+
+
+pcp-2.1.8-2 (released 30 June 2000)
+    - fix for bug #793871 pmlogger_check fails after redhat upgrade
+      (because PCP entries in /usr/share/magic were clobbered)
+    - also install /var/pcp/pmdas/linux/pmdalinux (as a non-DSO
+      agent for debugging and profiling purposes).
+    - added pmda.uname (uname -a) and pmda.version (linux pmda version)
+      metrics. The pmda.uname metric is needed by the "pcp" command.
+    - fix for #789025 fix to ensure rpm --verify succeeds immediately
+      after an install, and other errors in pmlogger_check
+    - released with ACE 1.3 (MR 19 Jul 2000)
+
+pcp-2.1.7 (internal release for testing)
+    - merged changes from IRIX for multiple namespace support in
+      pmdaproc.sh
+    - parameterized path to pmcd.conf and pmcd.options to avoid
+      having to move these files in IRIX. Use PCP_PMCDCONF_PATH and
+      PCP_PMCDOPTIONS_PATH respectfully.
+    - add new error define PM_ERR_LOGFILE (reconciled from IRIX)
+    - conditional pragma for pmGetConfig (not used in linux)
+    - use if defined(HAVE_OBJECT_STYLE) to guard __pmCheckObjectStyle
+      since it's not used in linux (reconciled with irix code)
+    - correct logic used to scan for pmlogger pid in pmlogger_check
+      in case where pmlogger exits prematurely, part of #789025
+    - added -Wall to default CFLAGS and LDFLAGS
+    - added xfs metrics (needs kernel support else no values available)
+      extracted from /proc/fs/xfs/stat
+    - added nfs (version 3) metrics, same names as on irix, bug #789669
+    - fix instance domain for kernel.percpu.interrupts, bug #790372
+
+pcp-2.1.6 (released 3 May 2000)
+    - released with ISE 1.2 (MR 25 May 2000)
+    - released with ISEMAIL 1.0 (MR 24 May 2000)
+    - this is the version shipped with SGI ProPack1.3
+    - change use of __clone to pthread_create for portability
+    - add support for raid disk stats (previously ignored)
+    - fix for bug #789425 pmie suspect behaviour with "delta" keyword
+    - add support for devfs style scsi disk names
+    - fixed a problem where nfs stats were always showing NFSv3 stats
+      rather than NFSv2 stats. We are not (yet) supporting NFSv3 stats.
+
+pcp-2.1.5 (released 12 April 2000)
+    - released with SGI ACE 1.2 (MR 19 Apr 200)
+    - fix bug #786743 filesys metrics are wrong
+    - fix potential segfault bug in timezone handling
+    - tolerate SUSE's location of magic file different to Redhat's
+    - tolerate no chkconfig on SUSE (use %postinstall create rc symlinks)
+
+pcp-2.1.4 (released 15 Feb 2000)
+    - fix for segfault src/pmdas/linux/pmda.c on linuxppc, found by
+      Dale F. Brantly <dale.brantly@sgi.com>
+    - fix build error in src/pmclient, was trying to use pmgenmap
+      without /etc/pcp.env, also found by Dale.
+    - setlinebuf(stdout) for all clients that loop
+      (fixes a buffering problem on alpha-linux).
+    - fixed some missing "{" in conditional variable assignments
+      in src/pmie/etc_init.d_pmie (found by lstep@free.fr)
+    - changed use of pmgenmap in build for pmclient and
+      pmkstat to be consistent (found by lstep@free.fr)
+    - don't assume clock tick rate is 100/second. Use the CLK_TCK macro
+      instead. Rearrange arithmetic in src/pmdas/linux/pmda.c where we
+      divide by CLK_TCK to avoid truncation in conversions from jiffies
+      to milliseconds.
+    - return "no values available" rather than PM_ERR_APPVERSION for
+      the metrics disk.{all,dev}.{read,write,total}_bytes since these
+      are not available on systems without the "sard disk patch".  This
+      is now consistent with requests for disk.partitions.* metrics.
+
+pcp-2.1.3 (released with 2.1.4)
+    - released with ISE 1.0 (MR 1 Mar 2000)
+    - added hinv.map.scsi metric as a map of SCSI devices (if any)
+    - added disk.dev.{read,write,total}_bytes
+    - filter devpts from filesys.* metrics to avoid FPE errors
+    - added support for new style Apache configuration file and
+      "silent" install to weblog scripts
+
+pcp-2.1.2 (released with 2.1.4)
+    - released with SGI ACE 1.0
+    - fixed date field in LSM
+    - install pmiestats.h for pmieconf
+    - renamed /var/pcp/config/pmafm/pcp-col to
+      /var/pcp/config/pmafm/pcp
+    - added network.{ip,icmp,tcp,udp} metrics
+      extracted from /proc/net/snmp
+    - fixed shell syntax error in pmlogger_daily(1)
+      (changed test -l to test -f)
+    - fixed problem with definition of __psint_t on 64bit machines
+    - fixed timezone problem with daylight saving
+
+pcp-2.1.1 (released 7 Dec 1999)
+    - initial pcp-2.1.1 open source release
