# AsyncAPI Spec 2.6.0 Release Notes

The new version of the AsyncAPI specification - 2.6.0 - is now available.

> This is a minor release and doesn't bring any breaking changes. You can switch to it by modifying the following value in your AsyncAPI file `asyncapi: '2.5.0'` into `asyncapi: '2.6.0'`

## Added Pulsar Bindings and Protocol to AsyncAPI specification

The specification now supports a new custom protocol through the bindings feature called [Pulsar](https://pulsar.apache.org/).

Here is an example of the server representation in Pulsar:

```yaml
servers:
  production:
    bindings:
      pulsar:
        tenant: contoso
        bindingVersion: '0.1.0'
```

And also an example of the channel representation in Pulsar:

```yaml
channels:
  user-signedup:
    bindings:
      pulsar:
        namespace: 'staging'
        persistence: 'persistent'
        compaction: 1000
        geo-replication:
          - 'us-east1'
          - 'us-west1'
        retention:
          time: 7
          size: 1000
        ttl: 360
        deduplication: false
        bindingVersion: '0.1.0'
```
