Flowable 7.0.0是Flowable引擎的第一个稳定版本，专注于Spring Boot 3、Spring 6和Java 17的升级。REST应用程序要求使用支持Jakarta 9的servlet容器/应用服务器。此版本重点关注BPMN、CMMN、DMN和事件注册引擎的主Flowable引擎和REST API。这意味着没有UI应用程序、内容和表单引擎，以及Mule和其他一些模块被移除。

• This is the first stable release for version 7 of the Flowable Engines focusing on the Spring Boot 3, Spring 6 and Java 17 upgrade.
• The REST application requires a servlet container / application server that supports Jakarta 9.
• This release focuses on the main Flowable Engines and REST APIs for the BPMN, CMMN, DMN and event registry engines. This means that there are no UI applications, no content and form engines and the modules for Mule and some others are removed.
