Claude Exporter — v1.9.5 through v1.10.17 (shipped May 2026)

New features
- Backup & Restore: download all extension data (model snapshots, export
history, preferences) to a JSON file and import it back. Survives
uninstall/reinstall and moves between browsers/devices.
- Import modal: choose Merge (add missing entries, keep your current
values on overlap) or Replace (overwrite everything) before the file
picker opens.
- Options page: Date & Time format, Model Display preference (original
vs current), Contact & Diagnostics section with mailto + downloadable
diagnostics bundle (sanitized — all IDs redacted, no conversation
content).
- Browse dropdown: "Search projects" filter option (scopes the search
bar to project names instead of conversation names).
- Error capture: each context registers unhandled-error listeners that
push to a 50-entry ring buffer in chrome.storage.local. UUIDs are
redacted at capture time so no identifiers are ever persisted.

UX polish
- Popup: removed redundant "Org ID not configured" banner (auto-detect
handles it). Header title now reads from manifest.name so the testing
branch shows "Beta" automatically.
- Browse: "Edit Org ID" and "Advanced Options" open settings in the
same tab (back button works, bfcache pageshow triggers reload).
- Browse: settings dropdown / filter funnel / search bar / sort headers
are interactive immediately on page load instead of waiting for
conversations to fetch.
- Browse: View button removed (chat name was already a link).
- Browse: scrollable table behaves on narrow viewports (page scrolls,
not the table; header bg fills full width; checkbox right-anchored;
header text + sort icon stay on one line).
- Browse: "Export Selected" now exports every checked chat, including
ones currently hidden by the filter. Header checkbox still operates
only on visible rows.
- Browse: Model column gets a "*" bounce marker (same color as the
badge family) when current ≠ original. Tooltip on hover shows the
other model.
- Markdown export: includes truncated flag, file attachment metadata
(name/size/type), and now extracts artifacts from create_file
(skills-runner replacement for the legacy artifacts tool when
enabled_artifacts_attachments is false).

Bug fixes
- Single-export toast no longer triple-emits ("Exporting…" → "Exported
with N artifact(s)" → "Exported"). One unified toast that includes
the artifact count when applicable.
- Backup filename: claude-exporter-backup-YYYYMMDD-HHMMSS.json (matches
the conversation export timestamp format).
- Popup error wording: "Failed to obtain organization ID: Please set
this value in Options." with "Options" as a clickable link.
- Lowercased "Claude.ai" → "claude.ai" in user-facing strings.
- Removed "Test connection" from browse dropdown (already in Options
next to Save Settings).

[1.9.4]
Browse table's Model column now shows each chat's original (first-seen) model from the snapshot data, falling back to the current/inferred model when no snapshot exists
Bounced chats (original model differs from current) get a → marker with a tooltip showing "Originally X, now Y"
Model column sorting follows the displayed (original) model

[1.9.3]
Snapshot each conversation's current model to chrome.storage.local whenever the conversation list is fetched (browse page load or popup "Export All") — preserves the model before a chat gets bounced to a new one on model retirement
Records first-seen model, current model, and a change history per conversation; only the raw API model is stored, never an inferred guess

[1.9.2]
Added Vitest test harness for utils.js (52 tests covering export logic, model name parsing, artifact extraction)
Extracted model utilities (formatModelName, getModelBadgeClass, DEFAULT_MODEL_TIMELINE) out of content.js/browse.js into shared utils.js
Doc-linked the Anthropic model-ID schema in code comments
