Full Changelog: 1.2.3...1.2.4

• Improve stability and recoverability when running the KE in distributed mode
• Solve memory leak by too many unhandled handle requests

• Improve inter KER communication using timeouts, log statements and detecting unreachable KERs.

• Fixed a bug related to using authentication in distributed mode.

• Major improvements to the reasoner, making it more powerful. See this blog post for more information.
• It is now possible to provide Basic Authentication information within both the KE_RUNTIME_EXPOSED_URL and KD_URL environment variables that are used in distributed mode. This allows restricting participation in the data exchange to those who have a valid username and password. Note that Basic Authentication is only secure if combined with HTTPS and actually adding Basic Authentication and HTTPS requires the use of a correctly configured reverse proxy like NGINX.
• Improved knowledge base ID validation. This could be breaking if you use an invalid URL under certain circumstances.
• Knowledge base ID uniqueness check in distributed mode. If two knowledge bases currently use the same knowledge base ID in distributed mode (in different runtimes), it does not give a clear error in version 1.1.3 (although it probably behaves incorrectly), but in this version it will give a clear error when registering your knowledge base.
• This version requires Java 17 instead of Java 11.
