# Changelog
+## v2.1.36 (2026-06-28)
+
+### 首尾字稳定性修复
+
+- **Hold 模式首字保护扩展到所有模型**：按下热键后立即启动本地预采集，确认不是组合键后保留这段音频，降低 SenseVoice / Qwen3-ASR / Moonshine / Parakeet 等离线模型开头 1-2 个字丢失的概率。
+- **松键尾部采集保护扩展到所有模型**：松开热键后默认继续采集约 300ms 再停止录音，降低最后 1-2 个字被截断的概率。
+- **保留取消和组合键隔离**：组合键或过早释放仍会丢弃预采集音频，不进入识别流程。
+
+### 构建
+
+- build: `20260628.2354`
+- 说明: 本版本为首尾字稳定性修复的本地验证候选包。
