 ### Fixed
 
+- **Japanese UI is fully translated again.** The Japanese (`ja`) locale had drifted to English fallback across recent features (workspace panel, session sharing, extensions gallery, cron sentence-builder, composer, settings, and update flows); it is now refreshed to parity with the current English keys — 180 strings — so Japanese users no longer see a mixed-language UI. Thanks @koshikai. (#6403)
+
+- **Reloaded tool-call turns render with the same unified Worklog as live turns.** Historical transcripts using ID-linked tool calls (OpenAI-shape `assistant.tool_calls[].id` ↔ `role:tool.tool_call_id`) previously rendered through the legacy renderer after a reload or session switch, so a reloaded turn could look different from how it appeared live. Unambiguous, complete ID-linked turns now hydrate into the unified Assistant Turn Anchor before render, matching the live presentation exactly while failing closed to the existing renderer for any richer or ambiguous case. Thanks @franksong2702. (#6222, #6220)
+
 - **New chat: you can now hide the entire welcome panel, not just the suggestions.** A new opt-in Settings → Preferences toggle, "Hide new-chat welcome panel," hides the whole empty-state block (logo, heading, subtitle, and suggestion buttons) on an empty new conversation while keeping the composer available and focused. It extends the existing "hide new-chat suggestions" preference with the same persisted, hot-applied pattern; default is unchanged (panel shown). Thanks @vaidu-ai. (#6183, #6160)
 
 - **Workspace Artifacts pane: long filenames are fully readable and long parent directories stay inside the drawer.** A long artifact filename used to be ellipsized (so you couldn't tell files apart), and an unusually long immediate-parent directory could expand the Artifacts drawer horizontally and bleed past its edge. The list now shows the filename first with parent-preserving path truncation, and the directory tail is width-capped (`min-width: 0` + `overflow: hidden` + `text-overflow: ellipsis`) so it clips inside the card instead of blowing out the drawer. Adds behavioral/locale coverage for the artifact path lifecycle. Thanks @rodboev. (#6078, #6067)
