Next version

This release contains the following:

Features

• Waku v2 node support for secure websockets.

Changes

• Start of swap implementation
• Start of fault-tolerant store implementation
• Initial bridge implementation between Waku v1 and v2 protocols
• Initial lightpush implementation
• A peer manager for relay, filter, store and swap peers

Docs

Several clarifications and additions aimed at contributors, including

• information on how to query Status test fleet for node addresses,
• how to view logs, and
• how to update submodules.

Schema

• Add Message table to the persistent message store. This table replaces the old messages table. It has two additional columns, namely
  • pubsubTopic, and
  • version.

API

• JSON-RPC Admin API: Added a post method to connect to peers on an ad-hoc basis.
• Nim API: PubSub topic subscribe and unsubscribe no longer returns a future (removed async designation).
