Changelog

v0.2.0

Correctness & Security2026-09-12

Runtime messages are validated (shape, length, sender); selection / image / page interactions now target an explicit window
Storage trust boundary: content scripts can no longer read chrome.storage directly
New Autofill side-panel view: scan a job application, review the plan, then fill; sensitive fields are off by default and existing values are never overwritten
Anthropic native API adapter alongside the OpenAI-compatible adapter; per-profile vision model settings
Conversation state machine with explicit cancel / retry states; conversations persist in local storage and can be deleted anytime from the side panel
Security: marked 18 + DOMPurify 3.4, sanitized markdown, SSRF and size limits for remote images, search results treated as untrusted input
Accessibility: keyboard navigation, focus restore, status-only streaming announcements, IME-safe Enter, no forced scroll while reading
Engineering: 55 unit tests + 15 Playwright end-to-end tests, CI gates, whitelist packaging

UI Polish2026-08-12

Compact message bubbles with action buttons moved below each message; user-bubble left alignment fixed
Send button with three states (idle / streaming / stop), provider color dot on the model badge
Chat tables get zebra striping and header background; code blocks wrap long lines, copy button always visible
Settings page: all form controls unified to a strict 43px row, red delete button, right-aligned field hints, green autosave indicator
Selection toolbar: Lucide icons on buttons, shadow-DOM font loading fixed, max-width guard on narrow screens
Accessibility: explicit type=button everywhere, aria-expanded/pressed states, empty-state chips are real buttons
Fixed system messages showing an infinite spinner on static/error text
Dark mode contrast and desaturation fixes across the UI

Polish2026-08-04

4-step onboarding guide: pick provider → enter API key and pass connection test → choose model → done (skippable)
Persistent conversation history: stored locally, chat records survive extension updates
Streaming output now uses a blinking caret indicator instead of bouncing dots
New "back to bottom" button: appears while scrolling up, shows unseen message count
Selection popup panel positioning fixed after page scroll; auto-flips near viewport edges
Keyboard focus rings improved: visible focus on every element during Tab navigation, rounded corners preserved
Touch optimization: larger tap targets, actions always visible on touch devices
Dark mode polish: deeper code block surfaces, better theme harmony
Extension name simplified to "Deepdeep"
i18n: 185 translation keys × 4 languages (EN / 中文 / 日本語 / 한국어)
