This upgrade of feign-okhttp introduces a dependency on an alpha version of OkHttp (5.0.0-alpha.2), which contains behavioral changes that require verification.

Key Changes:

• Dependency on Alpha Release: The library now depends on an alpha version of okhttp, which is not considered stable for production use.
• TLS Cipher Suite Negotiation: The underlying OkHttp client now prefers the client's configured cipher suites over the JDK's default order. This may cause HTTP calls to negotiate different cipher suites than before, which could impact connections to servers with specific security configurations.
• Potential Memory Increase: A bug fix related to HTTP/2 flow control may increase memory usage for applications that make many concurrent calls and receive data faster than they can process it.

Recommendation:
Given the dependency on an alpha version of a critical library and the potential for behavioral changes in TLS negotiation, it is recommended to perform thorough testing in a staging environment that mirrors production, paying close attention to HTTPS connections and application memory usage under load.
