任务触发时支持动态传参，调度中心与API服务均提供提供动态参数功能

doc/XXL-JOB官方文档.md

 - 33、修复表字段 “t.order”与数据库关键字冲突查询失败的问题，
 - 34、调度中心提供API服务，支持通过API服务对任务进行查询、新增、更新、启停等操作；
 - 35、分片任务失败重试优化，仅重试当前失败的分片；
-- 36、任务参数数据框调整，手动触发时支持动态输入参数；
+- 36、任务触发时支持动态传参，调度中心与API服务均提供提供动态参数功能；
 
 
 ### TODO LIST
 - 9、执行器Log清理功能：调度中心Log删除时同步删除执行器中的Log文件；
 - 10、Bean模式任务，JobHandler自动从执行器中查询展示为下拉框，选择后自动填充任务名称等属性；
 - 11、API事件触发类型任务（更类似MQ消息）支持"动态传参、延时消费"；该类型任务不走Quartz，单独建立MQ消息表，调度中心竞争触发；待定，该功能与 XXL-MQ 冲突，该场景建议用后者；
-- 12、API任务触发时支持动态传参；
+- 12、调度线程池改为协程方式实现，大幅降低系统内存消耗；
 - 13、任务依赖增强，新增任务类型 "流程任务"，流程节点可挂载普通类型任务，承担任务依赖功能。现有子任务模型取消；需要考虑任务依赖死循环问题；
 - 14、任务告警逻辑调整：任务调度，以及任务回调失败时，均推送监控队列。后期考虑通过任务Log字段控制告警状态；
 - 15、新增任务默认运行状态，任务更新时运行状态保持不变；
 - 17、注册中心支持扩展，除默认基于DB之外，支持扩展接入第三方注册中心如zk、eureka等；
 - 18、流程任务，支持参数传递；
 - 19、SimpleTrigger 支持；
-- 20、调度线程池改为协程方式实现，大幅降低系统内存消耗；
-- 21、Release发布时，一同发布调度中心安装包，真正实现开箱即用；
+- 20、Release发布时，一同发布调度中心安装包，真正实现开箱即用；
