You can get the latest version on the downloads page.
New to this version is support for encryption of messages sent across the network. You can choose to encrypt on a per-attribute basis (for example, to encrypt only the password attribute of a server object), and it is recommended that you encrypt only sensitive information since doing so bloats the message size.
I have also standardized how your game communicates with App Engine, which should hopefully make it easier to deal with data client-side. Everything sent by the server as a response is encoded as JSON, chosen because of its brevity and because UnrealScript supports it natively. Now you can interact with the returned data as a SagResponse object rather than parsing it yourself.
If you have a feature you’d like to see in the next version of Sagittarius, you can add an issue at the GitHub Issues Page. Just be sure to tag it with the label “enhancement”. If you don’t have a GitHub account, you can always contact me with any suggestions or questions you might have.
Stay tuned for more updates!
