+
+I'm happy to announce that Chickadee 0.8.0 has been released!
+
+Chickadee is a game development toolkit for Guile.  Chickadee aims to
+provide all the features that parenthetically inclined game developers
+need to make 2D and 3D games in Scheme.
+
+Notable improvements and changes:
+
+* New `chickadee` executable for running games and producing
+  redistributable binary bundles for Linux. See [Command Line
+  Interface](/manuals/chickadee/Command-Line-Interface.html#Command-Line-Interface)
+  for more information.
+* Support for Guile < 3.0 has been dropped.
+* [Cube maps](/manuals/chickadee/Textures.html#Cube-Maps) are now a
+  supported texture type.
+* New procedural [3D mesh
+  generators](/manuals/chickadee/Meshes.html#Primitives-and-Meshes)
+  for planes, tesselated planes, cubes, and spheres in the `(chickadee
+  graphics mesh)` module.
+* New 3D [skyboxes](/manuals/chickadee/Skyboxes.html#Skyboxes) in the
+  `(chickadee graphics skybox)` module.
+* New [3D model loading](/manuals/chickadee/Models.html#Models) with
+  support for glTF 2.0 and OBJ files in the `(chickadee graphics
+  model)` module.
+* New [directional, point, and spot
+  lights](/manuals/chickadee/Lights.html#Lights) in the `(chickadee
+  graphics light)` module.
+* New
+  [Blinn-Phong](/manuals/chickadee/Meshes.html#Blinn_002dPhong-Materials)
+  lighting model for 3D meshes in the `(chickadee graphics phong)`
+  module.
+* New
+  [Physically-based](https://dthompson.us/manuals/chickadee/Meshes.html#PBR-Materials)
+  lighting model for 3D meshes in the `(chickadee graphics pbr)`
+  module.
+* New linear and radial gradient fills in the `(chickadee graphics
+  path)` module.
+* New `arc-to`, `bezier-path`, `right-split`, `up-split`,
+  `corner-split`, `square-limit`, `flip-horizontal`, and
+  `flip-vertical` procedures in the `(chickadee graphics path)`
+  module.
+* Clockwise arcs now supported by `arc` procedure in `(chickadee
+  graphics path)` module.
+* New mouse wheel event handler for `run-game`. (see [The Game
+  Loop](/manuals/chickadee/The-Game-Loop.html#The-Game-Loop))
+* `(chickadee math grid)` module moved to `(chickadee data grid)`.
+* `(chickadee math path-finding)` module moved to `(chickadee data
+  path-finding)`.
+* [Dynamic array API](/manuals/chickadee/Array-Lists.html) has been
+  made public.
+* [Queue API](/manuals/chickadee/Queues.html) has been made
+  public.
+* [Heap API](/manuals/chickadee/Heaps.html) has been made public.
+* New [quadtree](/manuals/chickadee/Quadtrees.html) spatial
+  partitioning structure in the `(chickadee data quadtree)` module.
+* New `current-timestep` parameter in `(chickadee game-loop)` module.
+* Tweens now use the current timestep as their default step value.
+* `vec2-dot-product` and `vec3-dot-product` are now named `vec2-dot`
+  and `vec3-dot` in the `(chickadee math vector)` module.
+* `2pi` is now `tau` in the `(chickadee math)` module.
+* New `look-at`, `look-at!`, `matrix3-inverse`, and `matrix3-inverse!`
+  procedures in the `(chickadee math matrix)` module.
+* `#v` reader syntax for vectors is now *deprecated* and will be
+  removed in a future release.
+
+Bug fixes:
+
+* Fixed implementation of `vec2-cross` and `vec3-copy!` in the
+`(chickadee math vector)` module
+* Fixed implementation of `matrix4-rotate!` in the `(chickadee math
+  matrix)` module.
+* Fixed looping of streaming sources in the `(chickadee audio)`
+  module.
+* Fixed implementation of `below` procedure in the `(chickadee
+  graphics path)` module.

+P.S. - The [2021 Autumn Lisp Game
+Jam](https://itch.io/jam/autumn-lisp-game-jam-2021) is coming up on
+October 15th!  There are lots of great ways to make games in Lisp
+these days, so there's never been a better time to join in on the fun!

+
+I'm happy to announce that Guile-SDL2 0.7.0 has been released!
+Guile-SDL2 provides Guile Scheme bindings for the SDL2 C shared
+library. The bindings are written in pure Scheme using Guile's foreign
+function interface.
+
+New bindings in this release:
+
+* SDL_SetTextureBlendMode
+* SDL_SetWindowIcon
+* SDL_ShowCursor
+* SDL_WarpMouseInWindow
+* SDL_WarpMouseGlobal
+
+Mouse wheel events are now supported.
+
+Thanks to Liliana Prikler for their contributions to this release, and
+the previous release which did not get a release announcement.
