+## [4.1.2] - 2025-11-16
+
+### Fixed
+- **Kimi API 401 errors** caused by deprecated model fields
+  - Removed `ANTHROPIC_MODEL`, `ANTHROPIC_SMALL_FAST_MODEL`, `ANTHROPIC_DEFAULT_OPUS_MODEL`, `ANTHROPIC_DEFAULT_SONNET_MODEL`, `ANTHROPIC_DEFAULT_HAIKU_MODEL` from Kimi settings
+  - Kimi API update now rejects requests with these fields (previously optional, now break authentication)
+  - Automatic migration removes deprecated fields from existing `~/.ccs/kimi.settings.json`
+  - Preserves user API keys and custom settings during migration
+  - Updated `config/base-kimi.settings.json` template
+  - Users experiencing 401 errors will be automatically fixed on next install/update
+
+### Changed

+
+---
+
+## [4.1.1] - 2025-11-16
+
+### Fixed

+  - Updated `scripts/postinstall.js` to copy `.claude/` before creating symlinks
+  - Updated `ccs update` command to re-install `.claude/` directory
+  - Supports Node.js 14+ with fallback for versions < 16.7.0
