3.1.0 (r1074)
~~~~~~~~~~~~~
	[build]
		-Add: make test in src/ and in the central Makefile

	[core]
		-Change: switching over from bison to byaccic; bison fails to provide a sustainable API
		-Fix: diagnostic: don't crash if there are no processes to print
		-Fix: make sure newly allocated fds have fd field set to -1 - the caller needs to fill i this field later
		-Fix: always initialize parser fields to 0, so line number is tracked correctly even when parsing from string
		-Fix: lines are counted from 0 so report syntax error with +1
		-Fix: don't crash if there are no processes 
		-Add: process properties: retval, retval_zero and retval_non_zero
		-Add: digagnostics: a call for trace dump
		-Add: debug trace reads and writes with -d

	[doc]
		-Add: proposed man pages for [socket]
		-Add: document the reconn parameter of socket
		-Add: example on how to embed an awk script
		-Add: plumb.1 source
		-Add: manual page for 69

	[regression]
		-Fix: last flush for [cmd] always requires a semicolon for proper termination and execution
		-Fix: race condition in pause_resume.pb; leave some time after the end of the last print so plumb has the chance to flush stdout
		-Change: enable running push-parser tests again

	[socket]
		-Add: new virtual process for networking

	[util]
		-Add: 69: stdio loop between two processes

	[virt]
		-Fix: tank: msg_t is too short, clashes on AIX



3.0.3 (r997)
~~~~~~~~~~~~
 [core] -Fix: fd_close() removes RP sink from the POLLOUT watch to avoid polling for dead/closed fds
 [core] -Fix: don't double free loopback pipes that are coming and going to the same process
 [core] -Add: help() for -h
 [tank] -Add: configurable datagram buffering
 [virt] -Add: vp_arg_atoi() and vp_arg_atof() - VPs use a central safe string to number conversion in their argument parsing
 [doc] -Fix: grammar in plumb.5
 [doc] -Fix: do install plumb.1


3.0.2 (r969)
~~~~~~~~~~~~
 [timer] -Fix: API CHANGE: don't print \n on stdout "msg"s
 [core] -Cleanup: compiler warnings
 [core] -Del: unused ->init callback; handled at creation of the VP or RP
 [core] -Change: generalize unbinding pipe from a process
 [core] -Fix: for sources of newly created RP use fd_rp_surce_poll() instead of manually setting POLLIN - the RP may be started up paused
 [core] -Fix: diagostics: don't segfault for NULL proc in resolving fd for printing (may happen when printing crash dump for alien FD)
 [core] -Fix: invalid memory write when reallocating fd array (happened when binding fd>=16)
 [core] -Fix: when reallocating fd array of a process, rebind the fd pointers stored in pipes - lack of rebinding caused crashes when binding more than 16 fds
 [virt] -Cleanup: compiler warnings
 [fixlen] -Add: comment the code as it is simple enough to be an example for developing VPs
 [doc] -Add: manual page for event (the event dispatcher)
 [doc] -Add: manual page for the plumb executbale (plumb.1)
 [doc] -Update: regex.3plumb for the recovered mml

3.0.1 (r945)
~~~~~~~~~~~~
 -Fix: install plumblib
 -Fix: shutdown procedure: when exiting, wait until all buffers are
       flushed before closing all fds
 -Fix: [regex]: substitution of text $ won't ruin the previous character
 -Change: allow VPs to write into a gorwing write buffer while still
          backpromoting blocking

 New regression tests:
 -Add: simple cat-prefix test to see if nothing is left pending in buffers
 -Add: test for binary end-of-record regex ($$)
