-# 1.2.1 Feb 29, 2020
+# CHANGELOG
+
+## 5.0.1 Mar 19, 2022
+
+- **Breaking change** For users of React Native, you are now required to add `import '@polkadot/wasm-crypto/initOnlyAsm'` at your project top-level to ensure that asm.js is initialized. (Or alternatively `import '@polkadot/wasm-crypto/initWasmAsm'` to future-proof when WASM does become available)
+- **Breaking change** For users who used to map the `data` and `empty` of the internal `wasm-crypto-{wasm, asmjs}` packages in their bundlers, swap to one of the `@polkadot/wasm-crypto/init*` top-level imports to set the type of interfaces you would prefer.
+
+Changes:
+
+- Add (optional) `@polkadot/wasm-crypto/init{OnlyAsm, OnlyWasm, WasmAsm}` to allow specific interface types
+- Add work-around for lazy secp256k1 init in asm.js environments
+- Optimize asm.js output size
+- Use latest `wasm-bindgen`, `binaryen` & `wabt` packages in build
+- Additional workaround for Vite bundling
+
+
+## 4.6.1 Mar 12, 2022
+
+Changes:
+
+- Adjust ed25519 internals, consistency in code
+- Ensure package path is available under ESM & CJS
+- JS wrapped bytes interoperability test
+- Adjust for bundlers where `import.meta.url` is undefined
+
+
+## 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
+
+
+## 2.0.1 Nov 8, 2020
+
+Changes:
+
+- Rework generation of WASM interfaces (proper cross-platform JS support)
+- Remove explicit `crypto` dependency, this is now applied by `@polkadot/x-randomvalues`
+- Build via xargo for panic abort, an overall small sizes without stack (Pinned nightly)
+- Move Rust library sources in to `rs/` subfolder
+
+
+## 1.4.1 Aug 27, 2020
+
+Changes:
+
+- Re-add the BTC/ETH compatible `bip39ToSeed` dropped in the previous version (ETH-compatible pairs)
+
+
+## 1.3.1 Aug 9, 2020
+
+Changes:
+
+- Add `scrypt` function for KDF generation
+- Remove `bip39ToSeed`, we only use the `bip39ToMiniSecret` variant in Substrate
+- Update ed25519-dalek to 1.0.0-pre.4
+- Rework generation based on latest wasm-pack generator
+
+
+## 1.2.1 Feb 29, 2020
+
+Changes:
 
 - Adjust build process for smaller wasm bundle outputs (~50K dropped from base bundle)
 - Unpin nightly from nightly-2020-02-17 version
 - Swap to yarn 2 and add support for use by yarn 2 projects
 
-# 1.1.1 Feb 24, 2020
+
+## 1.1.1 Feb 24, 2020
 
 - **Important** The sr25519 interface dropped the use of `verify_simple_preaudit_deprecated` for signature verification, instead it now uses `verify_simple`. Only schnorrkel 0.8+ signatures will now pass verification. This is a follow-up of the 0.1 signing support that was dropped in a previous version.
+
+Changes:
+
 - Rework schnorrkel signatures test vectors based on the above change (Rust, WASM and ASM.js tests)
 - Rust nightly pinned to last-known-working 2020-02-17 on CI (compiler issues, should to be reverted in a future release)
 
-# 1.0.1 Feb 15, 2020
+
+## 1.0.1 Feb 15, 2020
+
+Changes:
 
 - No functionality changes from 0.20.1. The interfaces here are stable in the current iteration.
 
-# 0.20.1 Jan 30, 2020
+
+## 0.20.1 Jan 30, 2020
+
+Changes:
 
 - Pull in schnorrkel 0.8.5 for full Substrate 2.x compatibility
 
-# 0.14.1 Sep 09, 2019
+
+## 0.14.1 Sep 09, 2019
+
+Changes:
 
 - No functionality changes at all, everything done is "under the hood" to give the codebase better maintainability
 
-# 0.13.1 Jul 20, 2019
+
+## 0.13.1 Jul 20, 2019
+
+Changes:
 
 - Added an asm.js fallback which is active for React Native via the `"react-native"` entry in `package.json`. Ensure that you run the build step with the `NODE_OPTIONS=--max_old_space_size=8192` flags, since the asm.js bundle is large. (For RN the full command would therefore be `NODE_OPTIONS=--max_old_space_size=8192 npm start`)
 
-# 0.12.1 Jul 17, 2019
+
+## 0.12.1 Jul 17, 2019
+
+Changes:
 
 - Remove deprecated `@polkadot/wasm-schnorrkel` & `@polkadot/wasm-dalek-ed25519` source (all combined in `@polkadot/wasm-crypto`, was kept for historical purposes)
 - Security dependency bumps
 - Updated Rust `hex-literal` for recent versions of the compiler (used in tests only)
 
-# 0.11.1 May 31, 2019
+
+## 0.11.1 May 31, 2019
