 # CHANGELOG
 
+## 4.5.1 Dec 3, 2021
+
+Changes:
+
+- Add `secp256k1{Compress, Expand, Recover, Sign}` functions
+- Remove all occurences of `.unwrap()` (match everywhere)
+- Adjust and optimize WASM function JS interface construction
+- Simplify base64 bytes decoding on construction
+
+
+## 4.4.1 Nov 22, 2021
+
+Changes:
+
+- Add `hmacSha256` & `hmacSha512` functions
+
+
+## 4.3.1 Nov 19, 2021
+
+Contributed:
+
+- Updated package.json to include repo (Thanks to https://github.com/v-zhzhou)
+
+Changes:
+
+- Add `keccak512` function
+- Add `sha256` function
+
+
+## 4.2.1 Aug 28, 2021
+
+Contributed:
+
+- Add sr25519 agreement external (Thanks to https://github.com/shelvenzhou)
+
+Changes:
+
+- Adjust tests to align with JS coding standards
+- Allow for optional build with Rust stable bootstrap
+
+
+## 4.1.2 Jul 9, 2021
+
+Changes:
+
+- Bump `@polkadot/dev` to allow for bundles with new-format
+
+
+## 4.1.1 Jul 7, 2021
+
+Changes:
+
+- Add an explicit `engines` field to `package.json`
+- Allow building as a completely stand-alone browser bundle (experimental)
+
+
+## 4.0.2 Mar 5, 2021
+
+Changes:
+
+- Add import indirection for both CJS & ESM (where generated source file is commonjs)
+
+
+## 4.0.1 Mar 4, 2021
+
+**Important** In the 4.0 version the default package type has been changed to ESM modules by default. This should not affect usage, however since the output formats changed, a new major version is required.
+
+Changes:
+
+- Build to ESM by default (with cjs versions via export map)
+
+
+## 3.2.4 Feb 24, 2021
+
+Changes:
+
+- Cleanup implicit dependencies, perform base64 decoding using base64-js
+
+
+## 3.2.3 Feb 16, 2021
+
+Changes:
+
+- Change package detect import to use `.js` source, not `.json`
+
+
+## 3.2.2 Jan 24, 2021
+
+Changes:
+
+- Remove `module` field in `package.json`
+
+
+## 3.2.1 Jan 22, 2021
+
+Contributed:
+
+- Expose sr25519 `ext_vrf_{sign, verify}` methods (Thanks to https://github.com/stiiifff)
+
+Changes:
+
+- Add explicit `.editorconfig` for Rust sources
+- Remove unused code bundles (`vrf_{sign,verify}_extra`, `secp256k1` with tests)
+- Test run wrapper cleanups
+
+
+## 3.1.1 Dec 19, 2020
+
+Changes:
+
+- Single-instance package detection
+- Adjust WASM inflate with localized methods
+
+
+## 3.0.1 Dec 13, 2020
+
+**Important** This assumes `@polkadot/util` 5+ peerDependencies
+**Important** While this package contains no external interface changes, it doe now compile and ship both cjs and esm modules. This means that modern bundlers will have more information for tree-shaking available. Additionally when using Node with `.mjs` extensions, the esm version imports will be used on recent Node versions. Adding an export map, as here, may have some impacts so a major semver bump is advised. There may be (small) dragons hiding in the dark corners...
+
+Changes:
+
+- Build and expose both cjs and esm via exports map
+- Split wasm and asmjs files into the `@polkadot/wasm-crypto-{wasm,asmjs}` packages
+- Add fflate WASM compression, with 180K raw savings (37K over-the-wire)
+- Convert the package to full TypeScript sources
+
+
