 api-observable has been removed. This was only used in /apps and inconsistent with the api/rx and api/promise APIs. Future work will include derives like was included in api-observable into the base.

 Changed the send signature (for future expansion of eg. events) to return `result: { status: ExtrinsicStatus }` instead of `status: ExtrinsicStatus`. For most cases where only status `type` checks are used, i.e. `status.type === 'Finalised'` this should not be a breaking change. Deep inspection of the status object however will need to adapt.

 To fix this, you should look at the specific `api.tx.*` params and adjust the type definitions for those param types to match what is found on the node side. In some rare cases the cause could be extrinsic formatting related, to track these make an `api.tx.system.remark(data: Bytes)` call, if it fails, the API and node cannot agree on [an extrinsic format and adjustments are required](types.extend.md#impact-on-extrinsics).

+If you are using a node-template based version of substrate and you changed the specName you need to add these typings(In addition to other custom types) `{"Address": "AccountId","LookupSource": "AccountId"}`. This is also the case when you use [polkadot-js/apps](https://github.com/polkadot-js/apps) to connect to your node. When the specName stays node-template the API is smart enough to add the custom typings.

 ## I would like to sign transactions offline

 The API itself is independent on where the signature comes from and how it is injected. Additionally it implements a signer interface, that can be used for external signing - an example of this is the [polkadot-js/apps](https://github.com/polkadot-js/apps) support for signing via extensions and even the [polkadot-js/extension](https://github.com/polkadot-js/extension) support for tools such as the [Parity Signer](https://github.com/paritytech/parity-signer).
