Notes on .exe build from revision 12739

2012-08-31

Enhancements:
- A more stable and complete OMC model compiler. The 1.9.0 beta version simulates more models than the previous 1.8.1 version.
- Better simulation support for MSL, e.g. 74 MSL 3.1 example models now simulate compared to 36 models for the 1.8.1 version. Almost all MultiBody example models (except 2) now simulate.
- Better simulation support for several other libraries, e.g. more than twenty examples simulate from ThermoSysPro, and all but one model from PlanarMechanics simulate.
- NOTE: this beta version does not support simulation of the Fluid library. That is the target for the final 1.9.0 release, planned for the October/November time frame.
- Improved tearing algorithm for the compiler backend. Tearing is by default used.
- Matching and dynamic state selection algorithms for the compiler backend.
- New index reduction algorithm implementation.
- Better initialization, including symbolic matrices for initialization.
- Better class loading from files. The package.order file is now respected and the file structure is more thoroughly examined.
- It is now possible to translate the error messages in the omc kernel.
- Enhanced ModelicaML version with support for value bindings in requirements-driven modeling available for the latest Eclipse and Papyrus versions. GUI specific adaptations. Automated model composition workflows (used for model-based design verification against requirements) are modularized and have improved in terms of performance.
- Improved FMI import to prepare for FMI for co-simulation.
- Checking (when possible) that variables have been assigned to before they are used in algorithmic code.
- Full version of Python scripting.
- Prototype support for uncertainty computations, special feature enabled by special flag.
- Parallel algorithmc Modelica support (ParModelica) for efficient portable parallel algorithmic programming based on the OpenCL standard, for CPUs and GPUs.
- Support for optimisation of semiLinear according to MSL 3.3 chapter 3.7.2.5 semiLinear.
- Various bugfixes.

Functionality from 1.8 that is missing in 1.8.1 but will be put back soon:
- Interactive simulation is not operational in this beta release. It will be put back again in the near future, first available as a nightly build. It is also available in the previous 1.8.0 release.
