+# Changelog
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
+
+## [3.0.0] - 2020-10-20
+## Added
+- New components:
+  - cDataPrintSink
+  - cFunctionalModulation (re-added from version 2.2)
+  - cFFmpegSource
+  - cExternalSource
+  - cExternalAudioSource
+  - cExternalSink
+  - cExternalMessageInterface
+  - cVectorBinaryOperation
+- New config files:
+  - GeMAPS v01b and eGeMAPS v01b (fixing a numeric instability)
+- SMILEapi: C API with language bindings for Python and C#.
+- iOS platform support and iOS sample app project.
+- Colorized log output.
+- Command-line option "-exportHelp" to export component help in JSON format for use by 
+  third-party applications.
+- The growDyn option is now supported for ring-buffer data memory levels.
+
+## Changed
+- Replaced Autotools-based build scripts with CMake.
+- Rewritten Android sample project using Kotlin and Gradle.
+- Major reduction in memory usage for data memory levels with high frame rates 
+  (e.g. raw Wave data).
+- Performance improvements for components cSpecScale and cFunctionalModulation.
+- Improved internal support for components that read data asynchronously from external sources
+  (e.g. sound card, network).
+- Documentation has been updated and is now provided in HTML format.
+- Numerous cleanups and refactorings.
+
+## Fixed
+- Numerous bug fixes and other smaller improvements.
+
+## Removed
+- Multi-thread processing has been removed for stability reasons.
+
+## [2.3] - 2016-10-28
+
+## Added
+- Android JNI integration.  
+  While version 2.2. did provide first support for compilation as static binary for Android,
+  we now offer integration into Apps via the JNI. An example project and a tutorial for 
+  Android Studio are provided which shows how to build a live audio analysis app that
+  shows audio parameters in real-time in the App UI.
+
+- Batch feature extraction GUI for Windows and batch extraction scripts for Linux.
+  These make it easier for beginners to extract audio features from a collection of audio files.
+
+- Updated Version of ComParE 2013-2015 baseline acoustic parameter set.
+  Several optimisations to the feature extraction code were applied and
+  an updated version of ComParE was released. It has the same features as 
+  the previous version, but is now numerically optimised. It is referred to
+  as ComParE_2016, as it is released in 2016. 
+  It is not the Interspeech ComParE 2016 baseline feature set (this is still the 2013 one)!!
+
+## Changed
+- Configuration file interface updated.
+  Commandline options for audio input and data output formats have been standardised
+  through modular config files.
+
+## Fixed
+- Improved backwards compatibility.
+  All standard feature sets are verified to be backwards compatible to Version 2.2 and 2.1.
+  The original feature sets of openEAR are also backwards compatible with 
+  the original openEAR models.
+
+- Lots of various fixes and improvements.
+  We've added many minor points, fixed bugs, and improved performance.
+  E.g. we have improved the support for modulation spectra as functionals and optimized 
+  Jitter computation through a better pitch period detection algorithm.
+
+## [2.2] - 2015-10-02
+
+## Added
+- Configuration files for the first release of the Geneva Minimalistic Acoustic Parameter Set 
+  (GeMAPS).
+
+## [2.1] - 2014-12-23
+
+## Added
+- Support for reading JSON neural network files created with the CURRENNT toolkit.
+- F0 harmonics component.
+- Fast linear SVM sink component for integrating models trained with WEKA SMO.
+- Various other minor new components and features.
+
+## Fixed
+- Improved backwards compatibility of the standard INTERSPEECH challenge parameter sets.
+- Various bug fixes.
+
+## [2.0-rc1] - 2013-05
+
+## Added
+- Many new components.
+- Extended documentation.
+- Multi-pass processing mode.
+- Support for synchronised audio-visual feature extraction based on OpenCV.
+
+## Changed
