The Alpaca Trade SDK is available in four programming languages: Python, TypeScript/JS, C#/.NET, and Go. Installing the SDK can be done using specific CLI commands for each language. The latest functionality for Alpaca APIs is shipped through these SDKs. Recently, new features have been added to improve the experience, such as support for updated bars subscriptions in both stocks and crypto streaming clients, and improved error handling when connection issues arise with live streaming clients. Additionally, Python 3.10 is now supported, and some long-overdue improvements have been made to the Long-Short example algorithm.
