 - Full featured character controller (though I will likely provide a simple example version in the demos, just without the full upstepping/downstepping/stance shifting feature set).
 - Dedicated vehicle type.
 
-The initial version will be split into incremental stages: alpha, beta, and release. The alpha was released on March 31, 2018.

-### Beta (July 47, 2018)
-The beta will still be missing some important pieces, but should be able to support most games.
-- Triangulated mesh colliders with boundary smoothing.
-- Tree-accelerated compound for larger collections of shapes.
-- Simulation-wide ray and shape casts.
-- A few additional common constraint types.

 Should be able to support the core features required by physically complex games.
 - Better handling of some dangerous performance corner cases in the solver.
 - Fully enabled CCD.
-- Convex hulls.
+- Convex hulls and cylinders.
 - Additional ease of use features, especially for supplying custom body properties to collision filtering and velocity integration.
+- All of the (important) constraints from v1.
 - More educational demos, including some deeper dives like showing how to create a custom voxel world collidable.
 
 ### Nice-to-haves 
-There are a few features which aren't fundamentally required for a release, but which are still high value. These might get pulled into one of the above milestones if possible. If they don't make it into the first version, they'll probably show up later.

 Once the initial version is ready, most of my time will move to things other than core engine development. Much of that time will be spent actually using the engine, so expect to see incremental enhancements and fixes driven by practical use.

 This is the repo for the bepuphysics v2 library, a complete rewrite of the C# 3d rigid body physics engine [BEPUphysics v1](https://github.com/bepu/bepuphysics1).
 
-The library is still in alpha. Many important features are missing, and many bugs likely remain.
+The library is still in beta. Many important features are missing, and many bugs likely remain.
 
-The BepuPhysics and BepuUtilities libraries target .NET Standard 2.0 and should work on any supported platform. The demos are built on .NET Core 2.0 and require DX11.
+The BepuPhysics and BepuUtilities libraries target .NET Standard 2.0 and should work on any supported platform. The demos are built on .NET Core 2.1 and require DX11.
 
 The physics engine heavily uses System.Numerics.Vectors types, so to get good performance, you'll need a compiler which can consume those types (like RyuJIT).
 
 To build the source, you'll need a recent version of Visual Studio with the .NET Core workload installed. Demos.sln references all relevant projects.
 
 ## Features
 
-The alpha contains a basic featureset:
-- Spheres, capsules, boxes
-- Simple compounds of the above, mainly for use in smaller shapes where acceleration structures wouldn't be helpful
+The beta contains:
+- Spheres, capsules, boxes, triangles
+- Compounds of the above
+- Meshes
 - Highly nonidiomatic APIs
 - Automatic sleeping/waking management
-- Ball socket, hinge, swivel hinge, and swing limit
+- Ball socket, hinge, swivel hinge, swing limit, twist servo, twist motor, twist limit, angular servo, and angular motor
 - Speediness
 
 It notably does *not* yet include:
 - Convex hulls, cylinders, cones, or other complex shapes 
-- Efficient compounds supporting many children
-- Meshes
+- Dedicated heightmap terrain meshes
+- Mesh-mesh collision detection
 - Bounciness, other than the frequency/damping ratio tuning
 - Continuous collision detection, other than the speculative margin
-- Scene-wide queries like ray casts or volume queries
-- Shape casts
 - Many useful constraint types
