#iOS#TestFlight Surge 5 5.21.0 (3051) is ready to test on iOS. What to Test: - 性能优化

#Mac#Beta Version 5.4.4-2581 - Added SRC-PORT rule for matching client port numbers. - IN-PORT/SRC-PORT/DEST-PORT three rules are categorized as port number rule types, supporting three kinds of expressions: - Directly writing the port number, such as IN-PORT,6153 - Port number closed interval: such as DEST-PORT,10000-20000 - Using >, <, <=, >= operators, such as SRC-PORT,>=50000 - Improve compatibility with HomeKit Accessory Protocol in gateway mode. - Bug fixes.

#tvOS#TestFlight Surge 5 5.21.0 (3050) is ready to test on tvOS. What to Test: - 优化 Ponte server 逻辑，在更新外部地址后，如果 iCloud 更新失败，将持续重试（旧版只会重试一次）

#Mac#Beta Version 5.4.4-2580 - Added SRC-PORT rule for matching client port numbers. - IN-PORT/SRC-PORT/DEST-PORT three rules are categorized as port number rule types, supporting three kinds of expressions: - Directly writing the port number, such as IN-PORT,6153 - Port number closed interval: such as DEST-PORT,10000-20000 - Using >, <, <=, >= operators, such as SRC-PORT,>=50000 - Improve compatibility with HomeKit Accessory Protocol in gateway mode. - Bug fixes.

#tvOS#TestFlight Surge 5 5.21.0 (3048) is ready to test on tvOS. What to Test: - 同步 iOS 版本更新

#iOS#TestFlight Surge 5 5.21.0 (3047) is ready to test on iOS. What to Test: - 修正在大型规则集（>50条规则）中，IP-CIDR 规则掩码为 32 时不生效的问题

#Mac#Beta Version 5.4.4-2579 - Added SRC-PORT rule for matching client port numbers. - IN-PORT/SRC-PORT/DEST-PORT three rules are categorized as port number rule types, supporting three kinds of expressions: - Directly writing the port number, such as IN-PORT,6153 - Port number closed interval: such as DEST-PORT,10000-20000 - Using >, <, <=, >= operators, such as SRC-PORT,>=50000 - Improve compatibility with HomeKit Accessory Protocol in gateway mode. - Bug fixes.

#iOS#TestFlight Surge 5 5.21.0 (3046) is ready to test on iOS. What to Test: Surge 脚本现在支持双引擎 1. JaveScriptCore (engine=jsc，之前版本使用的引擎) 优点： - 引擎初始化速度快，调用时开销低（延迟低） 缺点： - 由于 JSC 执行时存在于 NE 进程内部，回导致 Surge NE 进程内存用量大幅提高，可能导致因为内存超限而被系统终止。 2. WebView (engine=webview，最近版本使用的引擎) 优点： - 由于 WebView 的实际运行环境为另一个独立进程，这使得脚本的执行对 NE 进程的内存占用几乎没有影响，不会造成 Surge NE 进程因内存用量问题被终止。 - WebView 的 JS 执行环境可以使用 JIT，对于复杂的或 CPU 密集型脚本执行效率有大幅提升。 - 可以使用 WebAPI。 缺点： - 引擎的初始化时间开销略高 - 当需要在脚本和 Surge 间传递大量数据时，由于涉及跨进程通信，效率较低，在使用 binary-body-mode 处理较大请求时比较明显。 使用推荐： 1. 对于经常被调用的小型、简单脚本，如 Rule、DNS 类型脚本，建议使用 JSC。 2. 对于复杂的、内存用量高的脚本（如对 MB 量级的 Body 进行 JSON 解析），建议使用 WebView。 配置方法： 在脚本配置行中加入参数：engine，可配置为 auto，jsc，webview - 默认为 auto，在 webview 可用的环境下总是使用 webview - 如果脚本中使用了 WebAPI，应主动配置为 webview，这样在不支持 webview 的环境下，执行该脚本时将给予用户提示。 引擎可用性： - iOS：JSC 与 WebView - macOS - macOS 10.15 及以下版本：仅 JSC - macOS 11.0 及以上版本：JSC 与 WebView - tvOS：仅 JSC
