+### [ecs_bench_suite]
+
+![Summary results table](ecs-bench.png)
+_The full benchmark report is available [here][ecs_report]_
+
+This month [@TomGillen] (author of the [Legion][legion] ECS) released
+[ecs_bench_suite] - a suite of benchmarks designed to test and compare
+Rust ECS library performance across a variety of challenging circumstances.
+Later, the project was adopted by the Rust GameDev WG
+so that all Rust ECS developers can converge on a neutral,
+community-maintained benchmark.

+### [inline_tweak]
+
+![Demo with moving traffic lights](inline-tweak.gif)
+
+[inline_tweak] by [@Uriopass] is a library that allows you to
+tweak at runtime any number literal directly from your code.
+It works by parsing the file when a change occurs
+(inspired by [this blogpost][tuxedolabs-post] from Tuxedo labs).
+Usage example:
+
+```rust
+use inline_tweak::tweak;
+loop {
+    // Try changing the value while the application is running
+    println!("{}", tweak!(3.14));
+}
+```
+
+A `watch!()` macro that sleeps until the file is modified is also provided.
+
+The library is minimal, only requiring the `lazy_static` dependency
+to hold modified values.
+In release mode, the tweaking code is disabled and compiled away.

+### [yacurses]
+
+[yacurses] by [@Lokathor] is a cross-platform curses bindings crate that's
+small, simple, easy to understand, and most importantly safe to use.
+It wraps over `ncurses` on Unix and a bundled `pdcurses` on Windows.
+If you're looking to make a terminal-based roguelike
+(or any other terminal-based game), give it a try.
