 ## [Unreleased]
 
+## [0.8.50] - 2026-06-02
+
+### Added
+
+- Added a Windows NSIS installer release artifact and classroom/lab deployment
+  checklist, harvested from #2045 for #1987. The release workflow now builds
+  `CodeWhaleSetup.exe` from the canonical Windows binaries, and the installer
+  adds/removes only the exact current-user PATH entry.
+- Added deterministic session timestamps in session listings, receipt-export
+  boundary docs, and current-model turn metadata for routed/auto sessions.
+- Added exact AtlasCloud provider-hinted model ID pass-through for explicit
+  `vendor/model-id` selections, harvested from #2569 without freezing a
+  brittle provider catalog.
+
+### Changed
+
+- Hardened theme repainting and sidebar color use so theme switches do not
+  leave stale Whale-dark panel colors behind.
+- Made legacy config migration visible when CodeWhale copies old DeepSeek-era
+  config into the CodeWhale config path.
+
+### Fixed
+
+- Fixed `/context` to use the effective routed model for context-window
+  budgeting, so DeepSeek V4 routes report the 1M-token window and legacy
+  DeepSeek routes keep the 128K fallback.
+- Fixed npm wrapper version output so `--version` prefers the installed binary
+  version instead of stale package metadata when both are available.
+- Fixed multiline composer arrow navigation so holding Up/Down at the first or
+  last line no longer replaces the current draft with prompt history.
+- Fixed foreground `exec_shell` output collection so timeout and inherited-pipe
+  cleanup cannot wedge later tool calls behind the global tool lock.
+- Clarified the English DeepSeek account-balance footer chip from `bal` to
+  `balance` so it is less likely to be mistaken for session spend.
+- Fixed truncated subagent tool calls and repeated truncated subagent responses
+  so they return model-visible errors instead of silently failing.
