v0.5.1

• avoid panic when peer is blacklisted after connection (#434)
• update dependencies

Note: This release is retracted because of bad dependency updates; please use v0.5.3.

v0.4.2

This is an intermediate patch release that cherry-picks/backports #427 and #430 from v0.5.0.

v0.5.0

This is a packed release, with bug fixes and new features.

Most importantly, Publish has become synchronous so that when a message is locally published, the validators are run inline, and if successful the message propagates in the network.
This ensures that locally published messages can never be silently dropped because of a full validation queue.

Complete Changelog:

• #397 -- Subnet whitelisting for IPColocation
• #403 -- Expose internal tracing with the RawTracer interface
• #406 -- Implement synchronous validation for locally published messages
• #410 -- Strengthen Validation Of Gossip Scoring Parameters
• #411 -- Demote log spam to debug
• #412 -- Ignore transient connections
• #413 -- Add support for custom gossipsub protocols
• #421 -- Refactor Gossipsub Parameters To Make Them More Configurable
• #423 -- Remove topic descriptors
• #427 -- Fix close of closed channel
• #430 -- Fix goroutine build up from connected notifications
• #432 -- More tracing, option to configure the Subscribe output queue length
