Earlier versions: V3 and V4

Willert Software Tools used to deliver frameworks identified by a number following the "WST" prefix. For example: WST52lt. Each number, like 52, stands for a combination of a toolchain, CPU and RTOS. It "lt" prefix was used, OO RTX by Willert Software tools was used as the runtime system.

What are the major changes coming with V5?

• The product names. Products are now named like composers, e.g. the V4 framework "WST52lt" is knows as "Beethoven" in V5. Appended to the product name you will find a version string like "V5.XrY". X is incremented every thime when we add new functionality or implement changes. Y increments with every bugfix release.
  
• The new V5 product has been setup in such way, that it allows you to install and use multiple versions
  next to each other in a safe manner, including a new V5 next to a V4 or V3 product.
  
• In V5, the Embedded UML Studio relies on an external build environment, namely the IDE which
  comes with your toolchain, where all generated files will be deployed or copied to. In earlier versions,
  the build process was carried out inside Rhapsody via a generated Makefile; in your Rhapsody model
  you therefore had to specify compiler options, startup file and linker details. This was all done via
  properties, and in V5 most of these details are configured entirely in your IDE.
  The advantage of this approach is that all tool dependant options can be used directly. Most of the
  time the user is already using the IDE to program his application and is comfortable with using all
  these options.
  Most IDE's deliver special dialogs to setup CPU specifics; they can be used then without having to go
  to difficulties to integrate the results in Rhapsody.
  When support questions concerning the result of the compiler come up, most compiler support
  departments demand a working IDE project before they supply support. With the new development
  procedure this is automatically generated.
  

Please use the examples in GettingStarted.pdf (which will be installed along with your V5 product) first so you get a feeling about how the new V5 product works. You can safely install it on your PC without breaking existing projects or Rhapsody, your
previous version and projects will be preserved.
