+## [1.21.3] - 2026-05-28
+
+### 发布概览
+- **远程凭据存储补丁版本** — 远程 SSH 凭据默认改为本地加密存储，减少系统钥匙串反复授权弹窗，同时保留系统钥匙串作为显式选项。
+
+### 用户可见更新
+- **远程凭据本地加密存储** — 远程主机密码和私钥口令现在可以保存到应用本地加密存储，不再必须写入系统钥匙串。
+- **凭据存储选择** — 远程主机新增/编辑弹窗现在支持按主机选择“本地加密”或“系统钥匙串”。
+- **钥匙串到本地加密迁移** — 编辑已有钥匙串凭据的主机并切换为“本地加密”时，如果旧凭据可读取，会自动迁移，不再静默保留旧的钥匙串引用。
+
+### 开发者与治理更新
+- **凭据引用前缀** — 远程凭据现在使用显式的 `local:` 和 `keychain:` 引用；历史无前缀引用仍按系统钥匙串读取，保持兼容。
+- **回归覆盖** — 新增本地加密凭据读写测试，以及编辑时密码/口令留空仍能从钥匙串迁移到本地加密的测试。

+## [1.21.3] - 2026-05-28
+
+### Release Overview
+- **Remote Credential Storage Patch** — Reduces repeated OS keychain prompts by making local encrypted storage the default for remote SSH credentials while keeping System Keychain as an explicit option.
+
+### User-facing
+- **Local Encrypted Remote Credentials** — Remote host passwords and private-key passphrases can now be saved in the app's local encrypted store instead of the system keychain.
+- **Credential Storage Selector** — The remote host editor now exposes a per-host credential storage choice between Local Encrypted and System Keychain.
+- **Keychain-to-Local Migration** — Editing an existing keychain-backed host and switching it to Local Encrypted now migrates the saved credential when it can be read, instead of silently keeping the old keychain reference.
+
+### Developer & Governance
+- **Credential Reference Prefixes** — Remote credentials now use explicit `local:` and `keychain:` references, with legacy unprefixed references still read from the system keychain for compatibility.
+- **Regression Coverage** — Added tests for local encrypted credential round-tripping and keychain-to-local migration when the password/passphrase field is left blank during edit.
