 # CHANGELOG
 
+## 2.8.1 Nov 23, 2020
+
+Upgrade priority: Low. Recommended if using Substrate master with new `MultiAddress`.
+
+Contributed:
+
+- Export `derive.chain.getBlock` (Thanks to https://github.com/lovesh)
+
+Changes:
+
+- Expand `MultiAddress` construction with multi type detection
+- Rename `GenericLookupSource` to `IndicesLookupSource` (internal use)
+- Cleanup list retrievals with `Raw` data results for undecodable entries
+- Export actual version via `RegistryMetadata`
+- Dedupe bn.js (one version shared between dependencies)
+
+
+## 2.7.1 Nov 16, 2020
+
+Upgrade priority: Medium. Recommended for users of Polkadot/Kusama and api-contract users.
+
+Changes:
+
+- Allow for `ExtrinsicSignature` overrides (defaults to `MultiSignature`)
+- Update api-contract `Blueprint` to allow for optional salt (auto if not provided)
+- Support for ink! `.contract` files (in addition to ABI `.json`)
+- Fix contract event decoding with pass-through of raw `Bytes`
+- Fix support for enum encoding in api-contract
+- Support new contract `Schedule` type as per Substrate
+- Update Kusama/Polkadot known upgrade blocks
+- Adjust typegen generated `@polkadot/types` imports
+- Adjust internal `@polkadot/types` imports/exports (overall bundle sizes)
+
+
+## 2.6.1 Nov 9, 2020
+
+Upgrade priority: Low. Should be done alongside an update to `@polkadot/util` to 4.0
+
+Changes:
+
+- Adjust auto-gas to contract RPC call to 5 * 10 ^ 12 (align with Rust)
+- Adjust derive `AccountId` check to take Ethereum-compatible chains into account
+- Fallback for chains with invalid council proposal data in derives
+- Bump static v12 Metadata (tests) to latest Substrate version
+- Bump `@polkadot/{util,util-crypto}` to 4.0 (optimized WASM layers)
+
+
+## 2.5.1 Nov 2, 2020
+
+Upgrade priority: Low. Recommended for `api-contract` developers.
+
+- **Breaking change** Substrate changed the `ContractExecResult` from `api.rpc.contracts.call`. The API does have pass-through support for both old and new variants via the `Contract` interface, however it means the structure has changed to accommodate the new Substrate structure. Refer to the [docs for the latest interface](https://polkadot.js.org/docs/api-contract/start/contract.read) (including `isSuccess/isError` -> `isOk/isErr`, and the availability of the `gasConsumed`)
+
+Contributed:
+
+- Dedup similar types on generation (Thanks to https://github.com/monitz87)
+
+Changes:
+
+- `Contract` execution will now return contract events decoded in the result
+- Add `.dryRun` on extrinsics (alongside `.paymentInfo` usage)
+- Add `system_syncState` and `syncstate_genSyncSpec` RPCs
+- Enhance error reporting, `Call` indicates explicit call as found
+- Adjust internal metadata decoration and use as exposed from `@types/metadata`
+- Expand Rococo known types to cater for v1 (specVersion 10)
+- `registry.hash` now returns an `H256` object (as opposed to raw Uint8Array)
+- Use utility logger in all relevant error messages (consistency in logging)
+- Add `derive.council.proposal(<hash>)` for retrieval of a single (expanded) proposal
+- Correctly and transparently format type generation types (allowing for nested variants)
+
+
 ## 2.4.1 Oct 26, 2020
 
 Upgrade priority: Low. No breaking changes, however it does move `api-contract` forward with additional features.

@@ -28,19 +28,3 @@ The API is split up into a number of internal packages -
 Type definitions for interfaces as exposed by Polkadot & Substrate clients -
 
 - [@polkadot/types](packages/types/) Codecs for all Polkadot and Substrate primitives
-
-## development
-
-Contributions are welcome!
-
-To start off, this repo (along with others in the [@polkadot](https://github.com/polkadot-js/) family) uses yarn workspaces to organise the code. As such, after cloning, its dependencies _should_ be installed via `yarn`, not via npm; the latter will result in broken dependencies.
-
-To get started -
-
-1. Clone the repo locally, via `git clone https://github.com/polkadot-js/api <optional local path>`
-2. Ensure that you have a recent version of Node.js, for development purposes [Node 10](https://nodejs.org/en/) is recommended.
-3. Ensure that you have a recent version of Yarn, for development purposes [Yarn >=1.10.1](https://yarnpkg.com/docs/install) is required.
-4. Install the dependencies by running `yarn`
-5. Build the everything via `yarn run build`
-6. You can also launch the API Docs, via `yarn vuepress dev docs`
-7. Access the docs via [http://localhost:8080](http://localhost:8080)

-# Docker compose file to run Polkadot-JS API e2e test files on supported versions of Polkadot and Substrate
-# 
-# Setup:
-# Builds 5 containers with different supported versions of Substrate and Polkadot.
-# Runs Polkadot-JS API Tests 
-#
-# Before you can run this script, you need to install Docker and 'Docker Compose' on your machine.
-# Please follow the steps described here (including the prerequisites): https://docs.docker.com/compose/install/
-#
-# Usage:
-# 1. BUILD: Run `docker-compose pull && docker-compose up -d` to pull the latest docker imaged and run docker-compose in detached mode. This will run the substrate and polkadot containers in the background.
-# 2. INFO: Run `docker ps` to get a list of Docker containers running in the background including their mapped ports on localhost
-# 3. TEST: Run `docker-compose logs -f js-api-tests` to run the API tests and print the logs
-# 4. QUIT: Run `docker-compose down` to stop and remove all running containers.
-#
-# Provided Endpoints for localhost:
-#   - Substrate Master: ws://127.0.0.1:9945/
-#   - Substrate 1.0: ws://127.0.0.1:9946/
-#   - Substrate 2.0: ws://127.0.0.1:9947/
