Hermes 0.3.0-beta

What's Changed

New Features

We are happy to announce the release of the Hermes Pub/Sub adapter. This adapter
provides users with the ability to interface with Hermes as if it were a message
queue or brokers, such as Rabbit MQ or Apache Kafka. The adapter has been
designed with usability in mind and creates, maintains, and manages all the
needed metadata for user operations. The adapter is intended to work on
workloads that might require an enhanced sense of order in their workload, as
the adapter imbues an additional organizational layer on top of the Hermes Blob
mechanism. Furthermore, the adapter can be used to establish ordered
communication between compute processes and it is the first step towards more
direct support of Hermes of Data Streaming workloads. See the wiki for more info.
