 ## [Unreleased]
 ### Added
+- Support for 448 DH function and Blake2s hash function.
 ### Changed
+- Using `crypto` over `enacl` (and removing a call to `get_stacktrace/1`) makes `enoise`
+  up to date for (at least) OTP-27.
+- Added test dependency `eqwalizer_support` to enable checking types with Eqwalizer.
 ### Removed
+- The dependency on `enacl` is not needed anymore, OTP's `crypto` library now cover all
+  necessary operations.
 
-## [4.3.1] - 2020-04-21
+## [1.2.0] - 2021-10-28
 ### Added
 ### Changed
-- Fixed included compiler binary file, which was broken due to incorrect local system dependencies.
+- Use the new AEAD crypto interface introduced in OTP 22. This makes `enoise` OPT 24 compatible
-  Because the aesophia version hasn't changed, the compiler in this release
+  but it also means it no longer works on OTP 21 and earlier. You can't win them all.
-  continues to report as `v4.3.0`.
+- Fixed ChaChaPoly20 rekey
 ### Removed
