We have deprecated the legacy Oso open source library. We have plans for the next open source release and we're looking forward to getting feedback from the community leading up to that point (please reach out to us in the Slack #help channel).

More context: [here](https://www.osohq.com/docs/oss/getting-started/deprecation.html).
