1.7.0 (01/01/2006)
-------------------
compiler/server:
- all time <-> float/double operators from postime.h also allowed/available for
  Poses++ compiler
- general change of expression sequence in backtracking. From now all expressions
  (card, match, cond, time) in all arcs will be processed from left to right and
  arc by arc from first to last so side effects like assignments to local variables
  could be used fully transparent.
- so called "search arcs" implemented. Search arcs will act similarly to test arcs
  but without reserving or keeping token capacity. So with a search arc you will
  "see" in difference to test arcs and similar to inhibitor arcs already kept
  tokens too.
  A match variable firstly assigned on a search arc can be used differently to inhibitor
  arcs also in expressions of following arcs.
  For search arcs is "??" used as arc operator. For symmetry reasons the new inhibitor
  arc operator is now "!!" . The old inhibitor arc operator "!>" keeps valid for
  compatibility reasons.
system:
- support for gcc-4.0.1 added
- support for 64bit (x86_64) Linux systems added
- support for Borland CBuilder5 and CBuilder 6 added
- support for Microsoft Visual C++ 7.1 (Microsoft Visual Studio .NET 2003) added
- support for Microsoft Visual C++ 8.0 (Microsoft Visual Studio .NET 2005) added

1.7.2 04/02/2006
----------------
- as preparation for a completely new developed client software a new command
  "onevent" is implemented at server side to allow common client defined tcl script
  reactions for any client applications. The old event behaviour controlled
  by the command "eventmask" was changed only by the additional option "message".
- posgraph.dll instead of posgraf.dll is now implemented to read incoming data
  multi threaded and so independent from the state of Windows GUI.

1.7.3 04/27/2006
----------------
- posclient-API (posclient.h/posclient.dll/libposclient.so) prepared for a
  mutlti thread environment.
- for the new client the server command "onevent" got additional parameter
  "level" to control the update level the event is invoked in.

2.0 04/24/2008
-----------------------
- various changes due to a new client development
- new front end client posdesk.exe substitudes older front end poside.exe
- support for gcc-4.1.x added
- support for gcc-4.2.x added
- support for Microsoft Visual Studio 2008 added (vc90)
- extremly improved speed for animation client

2.1 11/22/2009
-----------------------
- API wrapper module PosClient.cs for CSharp client development added
- API wrapper module PosClient.java for Java client development added
- PosesPlayer.exe a new CSharp based animation client added
- support for gcc-4.3.x and gcc-4.4.x added
- tcl scripts as examples to access the simulation server added

2.1p? 02/21/2010
----------------
- bug fix for animation files with corrupt compound blocks written by the animation player

2.2 11/24/2013
----------------
- bug fixes in posdesk.exe

2.3 23.04.2021
--------------
- C++ compiler of Visual Studio 2010 and 2017 added

2.4 24.05.2023
--------------
- C++ compiler of Visual Studio 2022 and gcc 11 added
