  | | |   |      Please report this when making bug reports.
  | | |   `----- Changes in /common/ code, or simply a significant number
  | | |          of bug fixes, gets a "build fraction" change.
  | | `--------- New cores, for any platform, will be accompanied by a
  | |            "build version" change, ie 2.7103.x to 2.7104.x+1.
  | |            New significant feature(s) also increment build version.
  | `----------- A "client contest" change follows a code freeze at which
  |              point the client is assumed to be stable. Code that
  |              would make clients incompatible with previous clients or
  |              proxies will be a accompanied by 'client contest' change.
  `------------- Denotes a client rewrite.

2.8008.459  new: x86: new rc5 K7 core thanks to
                 Sean Stanek <vulture@iastate.edu>
            new: all: the "update frequently (-frequent)" has been superseded
                 by "additional buffer-level checking". The new option
                 provides better control and supports one new mode
                 "update on per-project buffer exhaustion" which enables
                 old-style single-contest crunching (disables rotation).
                 See also: http://faq.distributed.net/cache/176.html
            new: all: out-buffer thresholds have been removed entirely;
                 use the "additional buffer-level checking" to support
                 updating/flushing more frequently than buffer exhaustion.
            chg: all: time threshold uses fetch work threshold > 0 as minimum
                 number of workunits to be fetched.
            new: all: -btime <pn> <n> complements time-driven threshold
            chg: all: -b[in] <pn> <n> now clears time threshold for <pn>.
            new: all: exit flagfile filename is now configurable.
            chg: macos: now supports all variants of System 7
            fix: Linux: dynamic import of dns resolution functions for better
                 glibc/libc cross compatibility (one shoe fits all again).
            fix: winnt: pause on process handling optimized and rewritten.
            chg: all: checkpointing now done at 10% or 10 minute intervals,
                 instead of 10% with 10 minute minimum.
            fix: all: project switchover no longer 'hangs'.
            fix: all: OGR nodecount network packet ordering fixed.

2.8007.458  fix: all: the annoying OGR 1 node bug finally fixed
            new: all: client can be configured a) to restart itself
                 on .ini change; b) (on most platforms) to pause itself as
                 long as process/executable x|y|z|... is running.
            fix: win32: use NULL DACLs for CreateMutex.
            chg: macos: numerous minor interface improvements
            new: macos: multiprocessor support (MP 2.x enhanced)

2.8005.453  chg: client supports thresholds either as a time-factor, or
                 as a workunit-factor. -config documentation has more info.
                 A review of your settings is *strongly* advised.

2.8004.452  chg: all: .ini option spin off from the generic [parameters]
                 section into subsections is now complete. phew! Nothing
                 left except "id".
            chg: reverted log file opening on win/dos/netware/os2 to
                 non-shared.

2.8004.451  fix: OS/2: Fixed crash in -config by using different API calls

                 native threads bound to LWPs instead of pthreads)
            chg: log file is opened shared on win/dos/netware/os2
            chg: log file is opened with persistant handles on *nix

            fix: solaris: time stamps/elapsed time on MP boxes
            fix: all: clients will again reset work if the core # changes
                 (functionality was lost in 2.8002.446 - reset if client
                 version or platform changes was unaffected).

2.8003.448  new: x86: 50% faster CSC MMX core added. '6bit - bitslice'
                 replaces '6bit - called'
            fix: all: lines in mail/logfile are no longer truncated
            fix: all: pause by signal (by user) and pause by filename
                 are additive, that is, pause remains in effect as
                 long as either one is in effect.
            fix: all: completed/summary time is now elapsed wall clock
                 time again
            fix: x86: Cyrix 6x86 auto-selects CSC core #3 now.
            imp: all: threads no longer check external flags for shutdown/

                 cache footprint.
            fix: win32: win95B doesn't have a 'Lucinda Console' TrueType
                 font, so client avoids it now.
            chg: many: DES cores are no longer included
            imp: all: benchmarks have greater time precision (no longer
                 overshoot the end of the bench period)
            chg: *nix: client setsid()s and dups std handles to /dev/null
                 when started with -quiet/-hide

            new: *nix: client distribution includes a man page
            chg: all: auto keyserver name resolution now allows as many

            imp: win16: scheduling and idle detection has been rewritten
            new: win16/win32: client archive includes a screen saver. When
                 run some _other_ screen saver in the foreground and start

                 packet-size' is greater than 31.
                 *Warning*: do not share buffers between clients that have
                 the use of big packets enabled and clients older than
                 2.7109.440 since older clients will truncate the packets.
