 ## Added
 - WARNING: Breaking changes!
-- Seeds to multiple algorithims that depend on random number generation.
-- Drop `nalgebra-bindings` feature
 - Complete refactoring with **extensive API changes** that includes:
     * moving to a new traits system, less structs more traits
     * adapting all the modules to the new traits system
-    * moving to Rust 2021, in particular the use of `dyn` and `as_ref`
-    * reorganization of the code base, trying to eliminate duplicates
-- usage of `serde` is now optional, use the `serde` feature
-- default feature is now Wasm-/Wasi-first for minimal binary size
+    * moving to Rust 2021, use of object-safe traits and `as_ref`
+    * reorganization of the code base, eliminate duplicates
