v1.9.0

Highlights

• Async exception tracking - Procedures marked {.async.} are annotated with the list of exceptions they might raise
• Self-signed TLS certificates can be generated. These will be used with Quic and WebTransport

Breaking change

• Python3 and pip are introduced as a dependency due to mbedtls requiring them to generate some of its source code. In a subsequent release, we will attempt to remove this dependency on Python.
• The LPProtoHandler type has changed and now specifies raised exceptions in the async pragma, namely async: (raises: [CancelledError]). Consequently, all protocol handlers must also specify async: (raises: [CancelledError]).

Example, code constructs like:

proc handler(conn: Connection, proto: string) {.async.} = 
  try:
    ...
  except CancelledError:
    trace "Unexpected cancellation in handler"

should be changed to:

proc handler(conn: Connection, proto: string) {.async: (raises: [CancelledError]).} =
  try:
    ...
  except CancelledError as exc:
    trace "Unexpected cancellation in handler"
    raise exc

Note:

• async pragma adds raises: [CancelledError]
• CancelledError is propagate up the chain

⚠️ WARNING
Nimble will not be able to resolve this version because libp2p.nimble has not been updated to 1.2.0. You can still use this version with Nimble if you either use the commit hash instead of the version tag, or update libp2p.nimble. We suggest using the latest release version instead.
