### Added
- Examples: New Ethereum Private Message Using Wallet Encryption
[Web App](./examples/eth-pm-wallet-encryption/README.md)
example that demonstrates the usage of `eth_encrypt` API (available on
Metamask) and EIP-712 for typed structured data signing.
- New `bootstrap` option for `Waku.create` to easily connect to Waku
nodes upon start up.
- Support for `startTime` and `endTime` in Store queries to filter by
time window as per [21/WAKU2-FTSTORE](https://rfc.vac.dev/spec/21/).
### Changed
- Renamed `discover.getStatusFleetNodes` to
`discovery.getBootstrapNodes`;
Changed the API to allow retrieval of bootstrap nodes from other
sources.
- Examples: Renamed `eth-dm` to `eth-pm`; "Direct Message" can lead to
confusion with "Direct Connection" that
refers to low latency network connections.
- Examples (eth-pm): Use sign typed data EIP-712 instead of personal
sign.
- Upgraded dependencies to remove warning at installation.
- **Breaking**: Moved `DefaultPubSubTopic` to `waku.ts` and fixed the
casing.
- **Breaking**: Rename all `pubsubTopic` occurrences to `pubSubTopic`,
across all interfaces.
### Removed
- Examples (cli-chat): The focus of this library is Web environment;
Several examples now cover usage of Waku Relay and Waku Store making cli-chat example obsolete;
web-chat POC should be preferred to use the [TOY-CHAT](https://rfc.vac.dev/spec/22/) protocol.
- `ChatMessage` has been moved from js-waku to web-chat example;
it is a type used for the [TOY-CHAT](https://rfc.vac.dev/spec/22/) protocol;
js-waku users should not build on top if this toy protocol and instead design message data structures appropriate to their use case.
- Unused dependencies & scripts.

### Added
- Relay and ReactJS guides and examples
([#56](https://github.com/status-im/js-waku/issues/56)).
### Changed
- **Breaking**: The `WakuMessage` APIs have been changed to move
`contentTopic` out of the optional parameters.
### Removed
- Examples (web-chat): Remove broken `/fleet` command.
- **Breaking**: Removed `DefaultContentTopic` as developers must choose
a content topic for their app; recommendations for content topic can
be found at https://rfc.vac.dev/spec/23/.
### Fixed
- `WakuMessage.payloadAsUtf8` returning garbage on utf-8 non-ascii
characters.
- `ChatMessage.payloadAsUtf8` returning garbage on utf-8 non-ascii
characters.
As developers must choose a content topic for their app.
The`WakuMessage` APIs have been changed to move `contentTopic` out of
the optional parameters. Recommendations for content topic can be found
at https://rfc.vac.dev/spec/23/.
It does not work as it can lead to infinite loops due to the handling of
the Waku instance. It should disconnect and reconnect to peers instead
of starting a new waku instance.
..on `Waku` with a default to 5min to send ping messages over relay
to ensure the relay stream stays open.
This is a workaround until
[js-libp2p#744](https://github.com/libp2p/js-libp2p/issues/744) is done
as there are issues when TCP(?) timeouts and the stream gets closed.
### Added
- Examples (web-chat): New `/fleet` command to switch connection between
Status prod and test fleets.
- Export `generatePrivateKey` and `getPublicKey` directly from the root.
- Usage of the encryption and signature APIs to the readme.
### Changed
- **Breaking**: Renamed `WakuRelay.(add|delete)PrivateDecryptionKey` to
`WakuRelay.(add|delete)DecryptionKey` to make it clearer that it
accepts both symmetric keys and asymmetric private keys.
### Fix
- Align `WakuMessage` readme example with actual code behaviour.
### Added
- `WakuRelay.deleteObserver` to allow removal of observers, useful when
a React component add observers when mounting and needs to delete it
when unmounting.
- Keep alive feature that pings host regularly, reducing the chance of
connections being dropped due to idle.
Can be disabled or default frequency (10s) can be changed when calling
`Waku.create`.
- New `lib/utils` module for easy, dependency-less hex/bytes
conversions.
- New `peers` and `randomPeer` methods on `WakuStore` and
`WakuLightPush` to have a better idea of available peers;
Note that it does not check whether Waku node is currently connected
to said peers.
- Enable passing decryption private keys to `WakuStore.queryHistory`.
- Test: Introduce testing in browser environment (Chrome) using Karma.
- Add support for Waku Message version 1: Asymmetric encryption,
symmetric encryption, and signature of the data.
### Changed
- **Breaking**: Auto select peer if none provided for store and light
push protocols.
- Upgrade to `libp2p@0.31.7` and `libp2p-gossipsub@0.10.0` to avoid
`TextEncoder` errors in ReactJS tests.
- Disable keep alive by default as latest nim-waku release does not
support ping protocol.
- **Breaking**: Optional parameters for `WakuMessage.fromBytes` and
`WakuMessage.fromUtf8String` are now passed in a single `Options`
object.
- **Breaking**: `WakuMessage` static functions are now async to allow
for encryption and decryption.
- **Breaking**: `WakuMessage` constructor is now private, `from*` and
`decode*` function should be used.
- `WakuMessage` version 1 is partially supported, enabling asymmetrical
encryption and signature of messages;
this can be done by passing keys to `WakuMessage.from*` and
`WakuMessage.decode*` methods.
- Examples (eth-dm): Use Waku Message version 1 encryption scheme
instead of `eth-crypto`.
- Examples (eth-dm): Use Protobuf for direct messages instead of JSON
([#214](https://github.com/status-im/js-waku/issues/214)).
### Fixed
- Disable `keepAlive` if set to `0`.
