v0.41.0

⚠︎ Breaking Changes

• This release updates go-multiaddr to v0.15 which has some breaking changes. This should not affect most users, but reference the go-multiaddr v0.15.0 release notes for breaking changes: https://github.com/multiformats/go-multiaddr/releases/tag/v0.15.0.

🔦 Highlights

Overall this is a fairly minor release focused on supporting the go-multiaddr v0.15.0.

• Update to go-multiaddr v0.15. This is a pretty big release for go-multiaddr that should make it harder to misuse. See the v0.15.0 release notes for breaking changes: https://github.com/multiformats/go-multiaddr/releases/tag/v0.15.0
• Uniform HTTP Peer ID Auth over native HTTP transport and HTTP over libp2p streams. See the http.Host Autthenticated HTTP example in the Go doc for an example of usage.
• Some upnp fixes that should make upnp/nat-pmp more reliable and easier to debug. This fixes an issue with FRITZ!Box routers.

v0.40.0

⚠ Breaking Change!

Introducing error codes mandated changing the error types returned by stream resets. All checks that depended on checking the error string or comparing equality with network.ErrReset, now need to use errors.Is(err, network.ErrReset). More details below in the error codes section.

🔦 Highlights

Error Codes

This releases introduces error codes for Stream Reset and Connection Close. This allows sending for more information to the peer about the error condition causing the abort. go-libp2p has already defined some error codes which are useful for many different use cases. You can find them in:
https://pkg.go.dev/github.com/libp2p/[email protected]/core/network#StreamErrorCode
and: https://pkg.go.dev/github.com/libp2p/[email protected]/core/network#ConnErrorCode

On streams, you can signal an error on reset by using:

str.ResetWithError(errCode)

On connections, you can signal an error on close by using:

conn.ResetWithError(errCode)

Not all transports support error codes. Most notably, WebTransport has no support for sending error codes at the moment. See the spec: libp2p/specs#623 for more details.

If you want to define custom error codes for your application protocol, you can reserve a block for your application by opening a PR in the specs repo. The above mentioned spec has details on reserving error codes for applications. Until the spec is merged, you must open a PR targeting the spec's branch.

Breaking Change!

This introduces a breaking change for users who checked stream reset errors by testing for equality with network.ErrReset as err == network.ErrReset. These tests now need to use the errors.Is(err, network.ErrReset) test. Stream Resets now return either *network.StreamError if the stream was reset by remote, or *network.ConnError if the connection was closed by remote.

v0.38.0

Highlights

• You can now use the same port for TCP and WebSocket. Refer to the
  TestSharedTCPAddr for an example on how to enable this. Currently this is
  opt-in. In a future release, we may enable this as default behavior when you
  leave the port unspecified or when you explicitly set the same port.

• The eventbus will now log error messages when it detects slow consumers. It's
  important for slow consumers to not stall the eventbus, as this can cause the
  core libp2p node to stall. Previously this was visible via metrics. This should
  help identify hard-to-debug issues without requiring metrics to be configured.
