 ## Library & Tooling Updates
 
+### specs 0.16
+
+[specs] is an entity-component system (ECS) library, designed for high
+performance. This update increases the MSRV to 1.38 and removes the `"nightly"`
+feature.
+
+In this version, the [panic message has been improved][panic_improve] to include
+the name of the type that is accessed on stable Rust, as well as suggestions for
+how to fix the issue. Prior to `specs 0.16`, retrieving a resource that had not
+been added to the `World` panics with an obscure *"resource not found"* message,
+and the `"nightly"` feature was necessary to discover what resource that is.
+
+In addition, the [`Send` and `Sync` trait constraints are
+removed][specs_constraints] from resources and `Component`s when the
+`"parallel"` feature is disabled -- enabling types such as
+`wasm_bindgen::JsValue` to be used with non-parallel `specs`.
+
+For more details, please see the [`specs` changelog].
