 ## Library & Tooling Updates
 
+### Piston
+
+Piston is a modular game engine written in Rust.
+
+A new Discord channel has been set up for the Piston project: https://t.co/8YOj3auDr9?amp=1
+
+Piston consists of a core library "piston" which itself are composed of smaller libraries for abstracting input, window and event loop.
+This design helps reducing breaking changes in the ecosystem.
+
+The core library `pistoncore-input` is now stabilized and reached 1.0!
+This is the most important core abstraction, because it glues all libraries that are not independent of the core.
+
+------
+
+Dyon is a rusty dynamically typed scripting language.
+It is developed and maintained as part of the Piston project, but can be used as a standalone library.
+
+Dyon is designed from the bottom up to be a good gamedev scripting language for Rust.
+It uses a lifetime checker instead of garbage collection, a mutability checker,
+optional namespaces and ad-hoc types, named argument syntax, 4D vectors and HTML colors, plus a lot more features!
+
+Recently, Dyon got better macro integration for native Rust types using `#` as a prefix.
+
+Here is an example of this feature is being tested in an experimental offline 3D renderer (not open sourced):
+
+```text
+// Called by `set_simple(scene: _, sdf: _, id: _)`.
+dyon_fn!{fn set_simple__scene_sdf_id(
+    scene: #&mut SimpleScene,
+    sdf: #&Sdf,
+    id: f64
+) {
+    scene.sdfs[id as usize] = sdf.clone()
+}}
+```
+

+
+Piston-Graphics is a library for 2D graphics, written in Rust, that works with multiple backends.
+
+`Stencil::Increment` has been added and the ecosystem has been updated to the latest version.
+
+------
+
+The research branch of the Piston project, AdvancedResearch, has released a new ECS library [Nano-ECS](https://github.com/advancedresearch/nano_ecs).
+
+This ECS design stores all components in a single array and uses bit masks for enabling/disabling components.
+An entity can have maximum 64 components and must be initalized with all components it uses in the future.
+Each entity has a slice into the array that stores all components.
+The `World` object, `Component` and systems are generated using macros.
+
+One research project with Nano-ECS is to prototype a UI framework for Rust with a UI editor (not open sourced yet).
+This project uses Piston-Graphics by default, but can generate draw commands for processing by other 2D APIs.
+It is also possible to override rendering of widgets for custom looks with Piston-Graphics, which is often useful in gamedev.
+Recently, this project has gotten to a place where [tree-view interaction](https://twitter.com/PistonDeveloper/status/1299840279374110720) is working.
