Olà amigos! This is an exciting week for us. Solace joined the AsyncAPI Initiative as a Platinum Sponsor 🎉. Thank you, Jonathan Schabowsky, for leading the process. And if that’s not enough, we finished our “Protocol mappings” milestone. Keep reading!

Latest changes in the specification

1. Protocol-specific information. This is a long-awaited feature. It allows you to define protocol-specific information in channels, operations, and messages.

2. Separate application headers from protocol headers. From now on, all the protocol-related headers must be included in a protocolInfo object, and the existing message headers must be used only for application headers, if any.

3. Annotate a channel parameter as multi-level. Do you want to tell your code a specific parameter should span across multiple levels? Now you can annotate channel parameters to indicate that. Pretty much like the # (pound) symbol in AMQP and MQTT or the > (greater than) symbol in NATS.

4. Unify examples fields. In the past, we had the example field in schemas and the examples field in some other places of the specification. They are now unified using the plural form and allowing for more than an example per object. However, we didn’t remove the support for example field in schemas, since we want to remain compatible with OpenAPI schemas.
