  |              proxies will be a accompanied by 'client contest' change.

                 and then splits it locally into sub-packets. Greatly
                 improves network throughput and reduces server load.

            new: all: the "update frequently (-frequent)" has been superceded
                 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;

            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.

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.

                 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".
