Release v2.16.0

on GitHub

Added

• Client-side subject validation for publish, subscribe and request, with a skip_subject_validation connect option to opt out (#1016)
• Allow user and password to be callables for credential refresh on reconnect (#891)
• StreamSource.consumer and AckPolicy.FLOW_CONTROL for pre-created sourcing consumers (#937)
• JetStreamManager.reset_consumer and ConsumerInvalidResetError (#941)
• Counter stream wire support (#940)
• Atomic batch publish headers and PubAck fields (#938)
• Message schedule header constants (#939)

Changed

• Validate header keys and sanitize header values before publishing (#1017)
• Subscribing to subjects with empty tokens or misplaced wildcards now fails client-side with BadSubjectError instead of a server error (#1016)

Fixed

• Default a missing port to 4222 and preserve the scheme and userinfo for every server in a URL list (#913, #1009)
• Resolve the WebSocket close task when a connection was never established, so close() no longer hangs (#993)
