See the [change log](CHANGES.md) for details.***\n\nEntity Component Systems (ECS) are a form of decomposition that completely decouples entity logic and data from the entity \"objects\" themselves. The [Evolve your Hierarchy](http://cowboyprogramming.com/2007/01/05/evolve-your-heirachy/) article provides a solid overview of EC systems and why you should use them.\n\nEntityX is an EC system that uses C++11 features to provide type-safe component management, event delivery, etc. It was built during the creation of a 2D space shooter.\n\n## Downloading\n\nYou can acquire stable releases [here](https://github.com/alecthomas/entityx/releases).\n\nAlternatively, you can check out the current development version with:\n\n```\ngit clone https://github.com/alecthomas/entityx.git\n```\n\nSee [below](#installation) for installation instructions.\n\n## Contact\n\nFeel free to jump on my [Gitter channel](https://gitter.im/alecthomas/Lobby) if you have any questions/comments. This is a single channel for all of my projects, so please mention you\u0027re asking about EntityX to avoid (my) confusion.\n\nYou can also contact me directly via [email](mailto:alec@swapoff.org) or [Twitter](https://twitter.com/alecthomas).\n\n## Benchmarks / Comparisons\n\nEntityX includes its own benchmarks, but @abeimler has created [a benchmark suite](https://github.com/abeimler/ecs_benchmark/blob/master/doc/BenchmarkResultDetails2.md) testing up to 2M entities in EntityX, the EntityX compile-time branch, Anax, and Artemis C++.\n\n## Rece",
