2022-01-19 v0.7

Release highlights:

• Support for secure websockets.
• Ability to remove unreachable clients in a filter node.
• Several fixes to improve store performance and decrease query times. Query time for large stores decreased from longer than 8 min to under 100 ms.
• Fix for a long-standing bug that prevented proper database migration in some deployed Docker containers.

The full list of changes is below. See #818 for more details.

Features

• Support for secure websocket transport

Changes

• Filter nodes can now remove unreachable clients
• The WakuInfo listenStr is deprecated and replaced with a sequence of listenAddresses to accommodate multiple transports
• Removed cached peerInfo on local node. Rely on underlying libp2p switch instead
• Metrics: added counters for protocol messages
• Waku v2 node discovery now supports 31/WAKU2-ENR

Fixes

• Fixed database migration failure in the Docker image
• All HistoryResponse messages are now auto-paginated to a maximum of 100 messages per response
• Increased maximum length for reading from a libp2p input stream to allow largest possible protocol messages, including HistoryResponse messages at max size
• Significantly improved store node query performance
• Implemented a GossipSub MessageIdProvider for 11/WAKU2-RELAY messages instead of relying on the unstable default
• Receiver timestamps for message indexing in the store now have consistent millisecond resolution

This release supports the following libp2p protocols:
