本版让内置浏览器工具有了独立开关，工作台能用满宽屏，模型服务可调整顺序，并修复行内技能调用发给模型的内容。
新增
- 设置 → 工具新增「内置浏览器」开关，由
[tools] browser_tools决定，未设置时开启；项目配置覆盖时显示实际生效的值 (#10898 by @esengine) - 模型服务可在设置中调整顺序，输入框的模型菜单和模型偏好按同样顺序列出；聚焦某一行时可用 Alt+↑/↓ 移动 (#10864 by @par73e)
变更
- 宽屏窗口中右侧工作台最宽可拉到 1600px；窗口变窄时暂时收窄，再变宽时恢复你拖出的宽度 (#10990 by @KHG420)
- 模型用
python -c等临时脚本自检时，会被告知这为何不算验证，并列出可认的验证命令 (#11001 by @esengine) - 后来的计划删掉已接受的验证命令时，交由你审批，不再由规划器自行决定 (#11024 by @esengine)
- 发布页为引用的合并请求注明作者、为问题注明修复它的合并请求，并在末尾列出贡献者 (#10984 by @esengine)
修复
- 只输入
/技能名或只放一个技能标签时，技能以与模型调用相同的形式发出，不再作为原始技能正文夹在你的消息里 (#11008 by @esengine) - 行内调用技能后，不再把技能正文里提到的其他技能当作必须调用，记忆检索按你输入的任务而非技能正文进行 (#11020 by @KHG420)
- 只把待办标记为完成、没有其他动作的回合，完成回执不再显示为「完成」 (#11014 by @esengine)
- 前台子代理用
sed -i等命令改动的文件能被识别，不再留下无法消除的未证实改动 (#11009 by @esengine, #11013 by @esengine)
升级须知
- 内置浏览器工具不再读取与 1.x 共用的
[browser] enabled：1.x 写入的enabled = false不会再关掉 Studio 的浏览器，Studio 保存设置也不会改动它 (#10898 by @esengine)

Full Changelog: studio-v2.20.2...studio-v2.20.3
macOS 已用 Developer ID 签名并公证，打开时不需要清除隔离属性。Windows 的窗口、内核与安装器都经 Certum 代码签名证书做了 Authenticode 签名。Linux 从 .deb 安装。
三个平台都能自更新：Linux 走自己的包，Windows 运行下一个安装器，macOS 替换自身 bundle。
