-# 1.0.1  Feb 15, 2020
+# CHANGELOG
+
+## 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
+
+- **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
+
+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

 - Updated Rust `hex-literal` for recent versions of the compiler (used in tests only)
