 ## [Unreleased]
 
-### Changed
 
-- Session-list SSE reconnects now use bounded jitter/backoff instead of a fixed 5-second retry, reducing reconnect bursts after restarts or network drops.
-- Expanded cron run rows now render the full output inline immediately; the truncated preview remains only for collapsed rows, and the full-output fallback no longer drops content when Markdown rendering is unavailable.
+## [v0.51.104] — 2026-05-21 — Release CB (stage-397 — 9-PR batch — i18n zh-CN/zh-TW cron status + geist-contrast skin polish + tablet hardware Enter + stale Codex slash model state + SSE reconnect jitter + cron run inline expansion + inflight send race + new-chat model provider sync + virtualized sidebar scroll-clamp resync + transcript cache invalidation on same-count content)
 
+### Fixed
+
+- **PR #2690** by @laiaman — Correct the zh-CN and zh-Hant translations for the `cron_status_active` label so it reads "enabled / scheduled" (`已启用` / `已啟用`) instead of "running" (`运行中` / `活躍中`). The English source is "active" (enabled, scheduled), and the prior Chinese strings conflated it with the separate `cron_status_running` "currently executing" state, making both labels look identical when a job was both scheduled and not currently firing.
+- **PR #2701** by @jasonjcwu — Geist-contrast skin composer polish: force `--user-bubble-text` to `#111` in light mode so typed text is black on the light input background; hide the textarea scrollbar to match the rest of the skin; recolor the send button so it reads correctly against the contrast palette.
+- **PR #2706** by @dobby-d-elf — Tablet (iPad-class) devices with an attached hardware keyboard now send on Enter and newline on Shift+Enter, matching desktop behavior. The prior touch-primary check forced Enter→newline on every touch device, but tablets with hardware keyboards have a physical Shift key and should follow the desktop contract. Detection uses `matchMedia('(pointer:coarse)')` + a `window.visualViewport` height-delta probe (>120px shrink = software keyboard open) so an iPad with hardware keyboard (viewport not shrunk) treats Enter as send, while a phone tapping into the composer (soft keyboard shrinks the viewport) keeps Enter as newline. Falls back to the legacy touch behavior when `visualViewport` is unavailable.
+- **PR #2684** by @ai-ag2026 — Repair stale `openai/...` slash-qualified model IDs when the active/session provider is `openai-codex`. A stale browser/localStorage selection of `openai/gpt-5` against an `openai-codex` provider previously routed the chat to OpenAI directly instead of through Codex. The cross-provider model-switch resolver now detects the mismatch and re-resolves the model to the matching `codex/...` ID before the request goes out. Explicit OpenRouter slash-qualified selections continue to fast-path through unchanged.
+- **PR #2671** by @AJV20 (closes #2629 + #2661) — Session-list SSE reconnects now use bounded jitter/backoff (each retry delay is `base*0.75 + random*(base*0.35)` where `base = min(30000, 5000 * 2^attempt)`, capped at 30s) instead of a fixed 5-second retry, so tabs that all dropped at the same time (server restart, network drop) don't all retry in lockstep. Expanded cron run rows now render the full output inline immediately on click; the truncated preview remains only for collapsed rows, and the full-output fallback no longer drops content when Markdown rendering is unavailable.
+- **PR #2689** by @ai-ag2026 — Preserve the optimistic in-flight message array across the `/api/chat/start` await window so a fast back-to-back send doesn't clear the user's message before the stream ID arrives. The fix snapshots the inflight entry before the await, recreates it if a sidebar/session refresh pruned it during that window, and skips stale-inflight cleanup for the submitting session until a stream ID is bound. Regression test covers the race.
+- **PR #2674** by @AJV20 — Resync the new-chat model picker when the server-created session has the same model ID as the current dropdown but a different provider. New conversations now resync to the configured default model provider instead of inheriting a stale persisted picker selection (e.g. `openai/gpt-5` from a previous session). Without this, the dropdown text matched the new session's model, but the provider attribute still pointed at the stale choice.
+- **PR #2688** by @ai-ag2026 — Resync the virtualized session sidebar after restoring a saved scroll position if the browser clamps or rejects that scroll position. Without this, date-group headers could render without their session rows beneath them until the user manually scrolled or a later refresh recomputed the virtual window. Regression test pins the recompute path.
+- **PR #2692** by @ai-ag2026 (refs #2613) — Invalidate the transcript render cache on same-count content changes, not just on count changes. The prior cache key was `(message_count, render_window_size)`, which silently reused a cached transcript whenever a same-count edit produced visibly different content (e.g. a tool retry that replaces a single assistant message with corrected text). The new cache signature folds a content hash into the key so any visible change forces a fresh render. Regression test asserts cache-bust on same-count content swap.
