Description
Version 3.2.2 is backward compatible to version 3.2.1, that is models developed withversions 3.0, 3.0.1, 3.1, 3.2, or 3.2.1 will work without any changes also with version 3.2.2(with exception of the, usually uncritical, nonbackwards compatible changes listed below with regards toexternal object libraries, and one bug fix introduced in 3.2.1 Build.3 for noncircular pipesthat can be nonbackwards compatible if a user constructed a new pipe model based onModelica.Fluid.Pipes.BaseClasses.WallFriction.PartialWallFriction, see details below).
 This version of the Modelica package is fully compatible to Modelica Specification 3.2 revision 2.
 About 240 tickets have been fixed in this release and the previous maintenance releases:
 Version 3.2.1 Build.3 (July 30, 2015) with respect to 3.2.1 Build.2 (August 14, 2013):
About 103 tickets have been fixed for this maintenance release.
 Version 3.2.1 Build.4 (September 30, 2015) with respect to 3.2.1 Build.3 (July 30, 2015):
 About 10 tickets have been fixed for this maintenance release. Critical tickets:
 Ticket 1768 fixes an issue with block CombiTimeTable (wrong output when using fixed time step integrator with time step greater than table resolution).
 Ticket 1758 states that simulation of Modelica.Fluid.Examples.HeatingSystem fails in Dymola 2016 if option "pedantic mode for checking Modelica semantics" is set. This issue was not fixed in the library due to the following reasons:
The Modelica.Fluid library uses a particular pattern to define some parameters resulting in a cyclic dependency of parameters if only incident information is taken into account. According to Modelica Specification 3.2 revision 2 this is not allowed (and therefore Dymola 2016 correctly reports errors if the pedantic flag is set). In ticket 1320 this issue was resolved for Modelica Specification 3.3 revision 1 by allowing cyclic parameter definitions if the cycles disappear when evaluating parameters that have annotation Evaluate=true. Modelica.Fluid is correct with respect to Modelica Specification 3.3 revision 1. Changing the Modelica.Fluid library for 3.2.1 build.4 so that no cyclic parameter dependencies would be present anymore would (a) result in a nonbackwards compatible change and (b) make the usage of Modelica.Fluid less convenient. For this reason Modelica.Fluid is not changed. (Practically, this means for example that the pedantic flag in Dymola 2016 needs to be switched off, when using the Modelica.Fluid library in version 3.2.1 build 4 and any previous version).  In ticket 1757 it is (correctly) stated that the example model PsychrometricData was moved from Modelica.Media.Air.MoistAir.PsychrometricData and that this is a nonbackwards compatible change. This nonbackwards compatible change is accepted, because it fixes a circular dependency (a model references a package in which it resides), for details see ticket 1679. Fixing this ticket is seen as of much higher priority, as the small drawback that an example model is moved (and the probability is very high that this moved model is not used in any user model).
 Version 3.2.2 Build.2 (March 16, 2016) with respect to 3.2.1 Build.4 (September 30, 2015):
About 130 tickets have been fixed for this release.
The ModelicaStandardTables object library (.lib, .dll, .a, .so, depending on tool) has been split into the libraries ModelicaStandardTables, ModelicaMatIO, zlib and the new object library ModelicaIO has been added.
For a tool vendor this can be a nonbackwards compatible change if the same object libraries have been used in the past for different releases of package Modelica. In Resources/CSources/readme.txt the issue is explained in detail and how to resolve it. For a user this might be a nonbackwards compatible change if he/she implemented an own external C interface function to one of the functions in the ModelicaStandardTables, ModelicaMatIO or zlib libraries. In this case, the library annotations to these functions need to be adapted.
 Version 3.2.1 Build.3 (July 30, 2015) with respect to 3.2.1 Build.2 (August 14, 2013):
 In version 3.2.1 Build.3 a new argument crossArea was introduced in the functions ofModelica.Fluid.Pipes.BaseClasses.WallFriction.PartialWallFriction to fix a subtle bug for thecalculation of pipe friction for noncircular pipes, see #1601and #1656.If a user utilized a pipe model of Modelica.Fluid.Pipes, this does not matter because the pipe models have beenimproved in a fully backwards compatible way. However, if the user constructed an own pipe model based onthe partial package PartialWallFriction and calls the functions defined in PartialWallFriction withpositional (and not named) arguments, then a unit warning or error will occur (depending on the tooland toolspecific settings) because the new argument crossArea has unit [m2] and the previousargument at this place, roughness, has unit [m]. If the warning is ignored, the simulation resultwill be wrong, because the crossArea is used as roughness. The user needs to fix this byadapting his/her pipe model so that the crossArea is used in the function calls,or by using named function arguments.
The exact difference between package Modelica version 3.2.2 and version 3.2.1 issummarized in the following two comparison tables:

The following new libraries have been added:
Modelica.Electrical.PowerConverters  This library offers models for rectifiers, inverters and DC/DCconverters. (This library was developed by Christian Kral and Anton Haumer). 
Modelica.Magnetic.QuasiStatic.FundamentalWave  This library provides quasistatic models of multiphase machines (induction machines, synchronous machines) in parallel (with the same parameters but different electric connectors) to the transient models in Modelica.Magnetic.FundamentalWave. Quasistatic means that electric transients are neglected, voltages and currents are supposed to be sinusoidal. Mechanical and thermal transients are taken into account. This library is especially useful in combination with the Modelica.Electrical.QuasiStationary library in order to build up very fast simulations of electrical circuits with sinusoidal currents and voltages. (This library was developed by Christian Kral and Anton Haumer). 
Sublibraries of Modelica.Magnetic.FluxTubes  New elements for modeling ferromagnetic (static) and eddy current (dynamic) hysteresis effects and permanent magnets have been added. The FluxTubes.Material package is also extended to provide hysteresis data for several magnetic materials. These data is partly based on own measurements. For modeling of ferromagnetic hysteresis, two different hysteresis models have been implemented: The simple Tellinen model and the considerably more detailed Preisach hysteresis model. The following packages have been added:

Sublibraries for noise modeling  Several new sublibraries have been added allowing the modeling of reproducible noise. The most important new sublibraries are (for more details see below): (These extensions have been developed by Andreas Klöckner, Frans van der Linden, Dirk Zimmer, and Martin Otter from DLR Institute of System Dynamics and Control). 
Modelica.Utilities functions for matrix read/write  New functions are provided in the Modelica.Utilities.Streams sublibrary to write matrices in MATLAB MAT format on file and read matrices in this format from file. The MATLAB MAT formats v4, v6, v7 and v7.3 (in case the tool supports HDF5) are supported by these functions. Additionally, example models are provided under Modelica.Utilities.Examples to demonstrate the usage of these functions in models. For more details see below. (These extensions have been developed by Thomas Beutlich from ITI GmbH). 
Modelica.Math sublibrary for FFT  The new sublibrary FastFourierTransform provides utility and convenience functions to compute the Fast Fourier Transform (FFT). Additionally two examples are present to demonstrate how to compute an FFT during continuoustime simulation and store the result on file. For more details see below. (These extensions have been developed by Martin Kuhn and Martin Otter from DLR Institute of System Dynamics and Control).

The following existing components have been changed in a nonbackward compatible way:
Electrical.Analog.Semiconductors.  
HeatingDiode  Removed protected variable k "Boltzmann's constant". Calculate protected constant q "Electron charge" from already known constants instead of defining a protected variable q. 
HeatingNPN HeatingPNP  Removed parameter K "Boltzmann's constant" and q "Elementary electronic charge". Calculate instead protected constant q "Electron charge" from already known constants. Users that have used these parameters might have broken their models; the (although formal nonbackwards compatible) change offers the users a safer use.
