Full Release Notes

## XHTTP client: Refactor "packet-up" mode, chasing "stream-up" #4150 

这是 2024 年最后一个版本，包含了大量重要更新：**比如再次优化了 XHTTP packet-up 模式的上行，修好了 bug 的同时速率直追 stream-up，还会自动切换连接以避免超过单个连接 HTTP 累计请求数限制，主要利好 H3 及穿透无流式上行的 CDN。** 更多的更新内容请看第三版 [XHTTP: Beyond REALITY](https://github.com/XTLS/Xray-core/discussions/4113)，还讨论了套 CDN 是否属于“滥用”的问题。

为了配合 XHTTP 对 TLS 的广泛使用，**Xray-core 已将 "chrome" 设为默认指纹**，防止手动输入配置时忘了选指纹。
