Release 0.8.0

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 [email protected] and [email protected] 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).

Fixed

• Disable keepAlive if set to 0.
