+## [0.1.3] - 2026-07-29
+
+### 新增
+- 本地识别模型支持自定义存储位置：模型文件较大，若系统盘空间紧张，可在「本地模式」设置里把模型改存到其它磁盘；更换目录后，已下载的模型会自动迁移到新位置。
+- 历史记录支持手工修改：可直接编辑整理后的文本，改完点击其它地方即自动保存（无需保存按钮，按 Esc 取消）；编辑过的记录会用小图标标记，便于日后辨认。
+
+### 修复
+- 修复用「右 Alt」等 Alt 键作为「按住说话」快捷键时，松开按键会呼出目标程序（如记事本）的菜单栏、使光标离开输入框，导致识别文本插不进去、日志却显示插入成功的问题。现已在系统按键层面正确拦截 Alt 键抬起，插入恢复正常。
+- 修复数字规范化把口语里的「一点」（表示"稍微、一点点"）误当成时间「1 点」的问题：如「调宽一点」不再被改成「调宽 1 点」。整点时间仅在有明确时间信号时才转换（如「下午一点」「一点钟」「十二点」）。
+- 修复关闭「AI 整理」后，默认的服务器模式下诊断页仍把「AI 校对」显示为正常的问题：现在无论哪种模式，关闭后都会明确显示为「未开启（极速模式）」。
