 # CHANGELOG
 
+## 6.10.2 Nov 30, 2021
+
+Upgrade priority: Low. Aligns TS augmentation and decoration with older behavior for ALL_CAPS identifiers.
+
+Changes:
+
+- Adjust augmentation interface consistency with top-level declarations
+- Update `@polkadot/util` to 8.0.4 with adjusted `stringCamelCase`
+
+
+## 6.10.1 Nov 29, 2021
+
+Upgrade priority: Low. Recommended for users of `HttpProvider` and for chains generating types using TS augmentation.
+
+Changes:
+
+- Fix for HttpProvider init (RPC sections with only subscriptions)
+- Re-order imports in lookup type augmentation interfaces
+- Bump static metadata for latest Substrate, Polkadot & Kusama
+
+
+## 6.9.2 Nov 22, 2021
+
+Upgrade priority: Medium. Pulls in `@polkadot/util-crypto` fix for TS projects.
+
+Changes:
+
+- Update `@polkadot/util-crypto` with TS compilation work-around
+
+
+## 6.9.1 Nov 21, 2021
+
+Upgrade priority: Medium. Recommended for metadata v14 parachains. For TS users, the package now support TypeScript 4.5.2 and allows extraction of user types from metadata v14.
+
+Contributed:
+
+- Lookup TS generation for all metadata v14 chains (Thanks to https://github.com/savudani8)
+- Update `BeefySignedCommitment` type (Thanks to https://github.com/czl1378)
+
+Changes:
+
+- Adjust runtime `*::{Call, Event}` matching for metadata v14
+- Adjust derive decoration with (optional) known methods
+- Expose `*{Call, Event, Error}` TS types for metadata v14
+- Align Option `.toJSON` output with Substrate input
+- Optimize Enum, Struct, Option & Number decoding paths
+- Ajust PascalCase conversions with function from util
+- Prepare pre-v13 types for optional injection
+- Adjustments for TS 4.5.2 support (flatten type infers)
+
+
+## 6.8.1 Nov 11, 2021
+
+Upgrade priority: Low. Recommended for chains with non-MultiSignature variants where `paymentInfo` is required.
+
+Changes:
+
+- Adjust `paymentInfo` signatures to cater for non-MultiSignature variants
+- Remove `::generic::` from names & namespaces under metadata v14
+- Add Polkadot 9122 upgrade block
+- Cleanup Polkadot/Kusama/Westend/Rococo known types (>= v14 metadata)
+- Internal `decorateMethod{Promise, Rx}` renamed to `to{Promise, Rx}Method`
+- Add RPC provider-level LRU for historic requests
+- Add optional known runtime version param to internal `rx.queryAt`
+
+
 ## 6.7.2 Nov 9, 2021
 
 Upgrade priority: Low. Recommended for chains on metadata v14 with non-default `Address` implementations.

+ * # @polkadot/api/rx
+ *
+ *  ## Overview
+ *
+ * @name ApiRx
+ *
+ * @description
+ * ApiRx is a powerful RxJS Observable wrapper around the RPC and interfaces on the Polkadot network. As a full Observable API, all interface calls return RxJS Observables, including the static `.create(...)`. In the same fashion and subscription-based methods return long-running Observables that update with the latest values.
+ *
+ * The API is well suited to real-time applications where the latest state is needed, unlocking the subscription-based features of Polkadot (and Substrate) clients. Some familiarity with RxJS is a requirement to use the API, however just understanding `.subscribe` and `.pipe` on Observables will unlock full-scale use thereof.
+ *
+ * @see [[ApiPromise]]
+ *
+ * ## Usage
+ *
+ * Making rpc calls -
+ * <BR>
+ *
+ * ```javascript
+ * import ApiRx from '@polkadot/api/rx';
+ *
+ * // initialize via Promise & static create
+ * const api = await ApiRx.create().toPromise();
+ *
+ * // make a call to retrieve the current network head
+ * api.rpc.chain.subscribeNewHeads().subscribe((header) => {
+ *   console.log(`Chain is at #${header.number}`);
+ * });
+ * ```
+ * <BR>
+ *
+ * Subscribing to chain state -
+ * <BR>
+ *
+ * ```javascript
+ * import { combineLatest, pairwise, switchMap } from 'rxjs';
+ * import { ApiRx, WsProvider } from '@polkadot/api';
+ *
+ *
+ * // initialize a provider with a specific endpoint
+ * const provider = new WsProvider('wss://example.com:9944')
+ *
+ * // initialize via isReady & new with specific provider
+ * new ApiRx({ provider })
+ *   .isReady
+ *   .pipe(
+ *     switchMap((api) =>
+ *       combineLatest([
+ *         api.query.timestamp.blockPeriod(),
+ *         api.query.timestamp.now().pipe(pairwise())
+ *       ])
