![12-0-wordcloud-hero.png](https://global.discourse-cdn.com/wolfram/original/3X/0/3/0391bfe8bcd3c962a196892211223b5d89dac5a7.png) We’re glad to announce that Version 12.0 of Mathematica and the Wolfram Language is here—and it’s a big one. This major update introduces several hundred new functions in a range of areas, including mathematics and geometry, visualization, audio and image processing, machine learning, and more, as well as provides a major overhaul to the Mac and Linux notebook interfaces and numerous systemwide performance enhancements. Some key new features include: ## Mathematics and Geometry - Convex optimization solvers such as [LinearOptimization](http://reference.wolfram.com/language/ref/LinearOptimization), [QuadraticOptimization](http://reference.wolfram.com/language/ref/QuadraticOptimization) and [SemidefiniteOptimization](http://reference.wolfram.com/language/ref/SemidefiniteOptimization), with vector inequalities such as [VectorGreater](http://reference.wolfram.com/language/ref/VectorGreater) for modeling vector-valued variables - Improved [NDSolve](http://reference.wolfram.com/language/ref/NDSolve) support for nonlinear PDEs using FEM and automated idealized _n_-body interaction using [NBodySimulation](http://reference.wolfram.com/language/ref/NBodySimulation) - Use [Around](http://reference.wolfram.com/language/ref/Around) to describe uncertainty in measured values, with built-in support in visualization functions - A host of new functions for generating, analyzing and manipulating polygons and polyhedra ([RandomPolygon](http://reference.wolfram.com/language/ref/RandomPolygon), [RandomPolyhedron](http://reference.wolfram.com/language/ref/RandomPolyhedron), [PolygonDecomposition](http://reference.wolfram.com/language/ref/PolygonDecomposition), etc.), with added support for holes/voids - Access built-in axiomatic theories for use in symbolic proofs with [AxiomaticTheory](http://reference.wolfram.com/language/ref/AxiomaticTheory) ## Visualization - [GeometricScene](http://reference.wolfram.com/language/ref/GeometricScene) and [GeometricAssertion](http://reference.wolfram.com/language/ref/GeometricAssertion) for visualizing Euclidean geometry and its theorems - Visualize different components and properties of complex-valued data and functions with [ComplexListPlot](http://reference.wolfram.com/language/ref/ComplexListPlot), [ReImPlot](http://reference.wolfram.com/language/ref/ReImPlot) and [AbsArgPlot](http://reference.wolfram.com/language/ref/AbsArgPlot) - Represent geodetic vectors with [GeoVector](http://reference.wolfram.com/language/ref/GeoVector) and visualize geodetic vector fields using [GeoVectorPlot](http://reference.wolfram.com/language/ref/GeoVectorPlot) and [GeoStreamPlot](http://reference.wolfram.com/language/ref/GeoStreamPlot) - Updated default appearance for [GraphPlot](http://reference.wolfram.com/language/ref/GraphPlot) visualizations, as well as new plot themes and updated properties - Create, analyze and modify chemical species with [Molecule](http://reference.wolfram.com/language/ref/Molecule) and visualize their 2D and 3D structures with [MoleculePlot](http://reference.wolfram.com/language/ref/MoleculePlot) and [MoleculePlot3D](http://reference.wolfram.com/language/ref/MoleculePlot3D) ## Audio and Image Processing - Color-processing functions such as [FindMatchingColor](http://reference.wolfram.com/language/ref/FindMatchingColor), [ImageRecolor](http://reference.wolfram.com/language/ref/ImageRecolor) and [ColorDetect](http://reference.wolfram.com/language/ref/ColorDetect), all powered by the new [ColorsNear](http://reference.wolfram.com/language/ref/ColorsNear) wrapper to represent a color neighborhood - Multi-language support for [SpeechSynthesize](http://reference.wolfram.com/language/ref/SpeechSynthesize), as well as improved discovery and searching of available voices through [VoiceStyleData](http://reference.wolfram.com/language/ref/VoiceStyleData) - [AudioAnnotate](http://reference.wolfram.com/language/ref/AudioAnnotate) framework for annotating audio objects - [ShortTimeFourier](http://reference.wolfram.com/language/ref/ShortTimeFourier) for computing and storing properties of short-time Fourier transforms and [InverseSpectrogram](http://reference.wolfram.com/language/ref/InverseSpectrogram) for approximating a signal from a magnitude spectrogram ## Machine Learning and Neural Networks - High-level recognition functions such as [ImageCases](http://reference.wolfram.com/language/ref/ImageCases), [FacialFeatures](http://reference.wolfram.com/language/ref/FacialFeatures), [AudioIdentify](http://reference.wolfram.com/language/ref/AudioIdentify) and [SpeechRecognize](http://reference.wolfram.com/language/ref/SpeechRecognize) - Additional pre-trained models, new layers, new encoders and decoders, and multi-GPU support for the neural network framework - Learn a generalized probability distribution from arbitrary data using [LearnDistribution](http://reference.wolfram.com/language/ref/LearnDistribution) - Replace missing values in data by generated values using [SynthesizeMissingValues](http://reference.wolfram.com/language/ref/SynthesizeMissingValues) and find anomalous examples in data using [FindAnomalies](http://reference.wolfram.com/language/ref/FindAnomalies) These are just a few of the highlights from this release, which also includes an experimental [Wolfram Compiler](http://reference.wolfram.com/language/guide/CodeCompilation), a comprehensive new [Microcontroller Kit](http://reference.wolfram.com/language/MicrocontrollerKit/guide/MicrocontrollerKit), a bidirectional [Unity](http://reference.wolfram.com/language/UnityLink/guide/UnityLink) game engine interface and expanded knowledge and functionality for [Entity](http://reference.wolfram.com/language/ref/Entity) and [EntityStore](http://reference.wolfram.com/language/ref/EntityStore). You can find out more about these and other Version 12 additions by reading through [Stephen Wolfram’s launch-day blog post](http://wolfr.am/launching-12) and looking at the [Summary of New Features in 12](http://reference.wolfram.com/language/guide/SummaryOfNewFeaturesIn12.html).
