4.0.070313
------------

+ ONS B3/[N7:0] was not working properly, i.e. ONS instruction using an
  indirect bit address.

+ Nexgen search would find "F8:1???" when searching for "F8:1".  Since searching
  is actually performed by the runtime, we had to fix it.

+ If a branch segment had no instructions on it, then Nexgen search would be off
  by the number of BLANK instructions inserted by Nexgen for display purposes.

+ Searching for the name of a TLIO or TLII without the TLIO or TLII opcode 
  argument was failing.  Searching for "TLIO LOADDATA" would work, "LOADDATA"
  would not work.
  

4.0.060622
------------
+ Switched to a new build system.  So everything is being compiled by a new
  environment.  Don't panic if you encounter a new runtime problem.  There is
  a miniscule chance this may happen, and that it may be attributable to the
  new build system.

+ When running as a daemon and not from the console, SoftPLC would not dispatch
  FNC_DEINSTALL to all the TLMs when the user killed the SoftPLC daemon.
  The dispatch would work fine when running from the console.  Fix involved
  a new /SoftPLC/run/libsoftplc.so and /etc/init.d/function script file.
  
+ Fixed a problem with FAL which disallowed using XOR, OR, AND functions 
  nested within.

+ Sorry, the 4.0 runtime had been shipping for many many months before we
  got this history.txt file going.
