# Changelog

## 0.2.1

- Docs only: README wording.

## 0.2.0

- `PlayerProfile.balances` (`CurrencyBalance[]`: `currency`, `balance`)
  replaces `wallets`, and the `Wallet` type is renamed `CurrencyBalance`.
- `PlayerProfile.items` (`InventoryStack[]`: `item`, `quantity`) replaces
  `counters`.
- Catalogs replace resources on the platform; no public type changes.
- Module clients generated by `rudder client generate` 0.3.0 list the current
  kernel error codes in `RudderKernelError`.

## 0.1.0

First release as `@rudder/sdk`. Not compatible with `@rudder/js-sdk` 2.x.

- `createClient({ projectKey })` creates the client; `baseUrl` defaults to
  `https://api.rudder.build`.
- Kernel surface only: `auth`, `player` (player, identities, wallets,
  `counters`), `catalog`, `storage`, `modules`. Revision sync keys are
  `profile`, `catalog` and `storage`.
- State objects expose `value` (was `data`), `status`, `error`, `load()`,
  `reload()` and `onChange()`.
- `storage.save(type, data)` upserts the single item of a type;
  `storage.delete(type)` removes it.
- `modules.call<T>(module, fn, args?, { moduleVersion? })` resolves to
  `result` as `T`. It always sends `args` (`{}` when omitted), one
  `Idempotency-Key` per call reused on retries, and
  `X-Rudder-Module-Version: <module>@<version>` when a version is given.
  Retries up to 2 times with jittered backoff on network errors, 5xx and 409
  `conflict`. A 422 rejects with `RudderModuleError<C>` (`code`, `message`,
  `requestId`).
- Typed module clients come from `rudder client generate --lang ts`.
- Removed: `client.resources(slug)`, `client.projectStorage` and their types.

## 2.x (@rudder/js-sdk)

Deprecated. Its history is in git before the 0.1.0 commit.
