= Release Notes for OpenModelica [milestone:1.11.0] =
[[PageOutline(2-3)]] 

The most important enhancements in the OpenModelica 1.11.0 release:
== OpenModelica Compiler (OMC) ==

New features:

- Real-time synchronization support by using simFlag -rt=1.0 (or some other time scaling factor).
- A prototype implementation of OPC UA using an [http://open62541.org open source OPC UA implementation]. The old OPC implementation was not maintained and relied on a Windows-only proprietary OPC DA+UA package. (At the moment, OPC is experimental and lacks documentation; it only handles reading/writing Real/Boolean input/state variables. It is planned for OMEdit to use OPC UA to re-implement interactive simulations and plotting.)

Performance enhancements:

- Code generation directly to file (saves maximum memory used). #3356
- Code generation in parallel enabled since #3356 allows this without allocating too much memory (controlled by omc flag `-n`).
- Various scalability enhancements, allowing the compiler to handle hundreds of thousands of equations. See for example [https://test.openmodelica.org/libraries/ScalableTestSuite_Experimental/BuildModelRecursive.html ScalableTestSuite] for some of the improvements.
- Better defaults for handling tearing (OMC flags `--maxSizeLinearTearing` and `--maxSizeNonlinearTearing`).
- Allowing mixed dense and sparse linear solvers in the generated simulation (chosen depending on simflags `-ls` (dense solver), `-lss` (sparse solver), `-lssMaxDensity` and `-lssMinSize`).
