 ## Library & Tooling Updates
 
+### [legion v0.3][legion-0-3]
+
+![Benchmarks](legion_violin.png)
+
+[Legion][legion] is among Rust's fastest and most powerful ECS libraries.
+After months in development, v0.3 has finally been released to crates.io.
+This is a huge release amounting to a near total rewrite of the library
+and a major step towards a stable 1.0 release.
+
+[Check out the v0.3 announcement post][legion-0-3]
+for an overview of the new API and all the updates.
+
+The project's repo has also been moved to the Amethyst org
+to reflect its close collaboration with the Amethyst community.

+### [Fontdue]
+
+[Fontdue] is a simple, no_std, pure Rust, TrueType & OpenType
+font rasterizer and layout tool.
+It strives to make interacting with fonts as fast as possible,
+and currently has the lowest end to end latency for a font rasterizer.
+
+Fontdue depends on [ttf-parser] for parsing fonts,
+which supports a wide range of TrueType and OpenType features.
+
+A non-goal of this library is to be allocation free and have a fast,
+"zero cost" initial load.
+Fontdue does make allocations and depends on the alloc crate.
+Fonts are fully parsed on creation and relevant information is stored
+in a more convenient to access format.
+Unlike other font libraries, the font structures have no lifetime dependencies
+since it allocates its own space.
+
+Project's roadmap:
+
+- v1.0: fontdue is designed to be a replacement for
+  rusttype, ab_glyph, parts of glyph_brush, and glyph_brush_layout.
+  This is a class of font libraries that don't tackle shaping.
+- v2.0: Shaping - the complex layout of text such as Arabic and Devanagari
+  \- will be added.
+  There are two potential pure Rust libraries (allsorts or rustybuzz)
+  that are candidates for providing a shaping backend to Fontdue,
+  but are relatively immature right now.

+### [ultraviolet v0.6][ultraviolet-v0-6]
+
+[ultraviolet] by [@fu5ha] is a crate for computer-graphics
+and games-related linear algebra, but _fast_,
+both in terms of productivity and in terms of runtime performance.
+
+This month [ultraviolet v0.6][ultraviolet-v0-6] was released.
+Updates include:
+
+- Support for 256-bit wide AVX vectors and instructions
+  as well as 128-bit wide SSE instructions which were already supported.
+- Support for f64/double precision floats under the f64 feature,
+  including f64x2 and f64x4 SIMD-accelerated types.
+- Support for [mint] for most scalar types.
+- Lots of smaller API and performance improvements.
