 ### Unrelated Changes
 
 Since we have made such sweeping API changes, we have also taken the opportunity to remove some deprecated functions. The following are no longer in the engine:
 
-- `pc.fw.RigidBodyComponent#get/setLinearVelocity` - use [`linearVelocity`](https://developer.playcanvas.com/en/api/pc.RigidBodyComponent.html#linearVelocity) property
-- `pc.fw.RigidBodyComponent#get/setAngularVelocity` - use [`angularVelocity`](https://developer.playcanvas.com/en/api/pc.RigidBodyComponent.html#angularVelocity) property
-- `pc.fw.RigidBodyComponent#get/setLinearFactor` - use [`linearFactor`](https://developer.playcanvas.com/en/api/pc.RigidBodyComponent.html#linearFactor) property
-- `pc.fw.RigidBodyComponent#get/setAngularFactor` - use [`angularFactor`](https://developer.playcanvas.com/en/api/pc.RigidBodyComponent.html#angularFactor) property

 Ever since we started the engine open source was always on our mind. We've never hidden the source code from developers. Minified versions are available for performance reasons, but during development users always have had full access to the un-mangled engine. This is critical for debugging and fulfilling our mantra to _make game development easier_.
 
-In reality the engine has been open source since the get go. Officially open sourcing the project was just a matter of time, and the time is now. The engine is mature enough that we've established the basic structure, style and functionality but contributors will still be able to make a meaningful contributions to the engine. And of course we've now found the time to lay down the foundations of the [developer documentation](https://developer.playcanvas.com), the [API reference](https://developer.playcanvas.com/en/api/), the [samples](https://playcanvas.github.io) and all the other stuff that makes game development a joy not a chore.

 For developers who just want to hack on the code with the overhead of the tools this news is great. Simply download the engine, open up your text editor and get cracking. For those of you who want more structure, and higher level tools, the [PlayCanvas platform](https://playcanvas.com) is a perfect addition to accelerate your game production.
