Release Notes for Prosys Sentrol 5.0.0

The main changes are to support the Unicode strings everywhere, when compiled with D2009. There are also some bug fixes here and there, and the storage components have been improved remarkably (once again) to actually support different databases (see the new Tutorial project).

Note in OPC development, that Delphi/C++Builder 2009 has changed in the way it initializes COM by default, so it no longer supports CoInitFlags for defining the COM threading model of the main thread (although this is not mentioned in Delphi Help). There is also a new chapter in the Help / Reference Guide about Threading Issues, which you should check.
