0.6.0

Released: 2026-06-01

New

Added the reading memory foundation, writing paragraph, selection, thread, and annotation memory to local storage and reusing existing judgment chains in later assistant generations.
Upgraded the AI assistant runtime into a traceable tool-call flow with selection actions, thread replies, co-reading tool loops, diagnostics, and AI SDK migration for the deep runtime.
Upgraded annotation discussions into standalone discussion windows and a distillation flow with assistant participation, distilled drafts, review assistant feedback, published distilled cards, and distillation stats.
Added the theme contract, theme picker, and reader paper background controls for unified web article, EPUB, and PDF reading visuals. PDFs keep original page colors on dark paper.
Improved Library and import experiences with web article covers and progress, batch file import, polished import dialogs, card stats hints, and PDF/EPUB metadata cleanup.

Cached lexical related passages to reduce repeated passage retrieval during long-article and long-book co-reading.
Optimized article import to avoid blocking UI responsiveness during import.
Skipped duplicate annotation memory backfills to avoid rerunning the same historical migration on startup.

Fixed PDF annotation anchors, overflowing list text, PDF dark paper colors, EPUB arrow-key pagination, and reader header drag regressions.
Fixed duplicate thoughts, thread memory sources, and tool-call stability in reading memory and assistant runtime.
Fixed Library page-size persistence, WeRead detail covers, ebook chapter note counts, ebook header cover hover, and implicit annotation metadata inference.
Polished annotation cards, assistant avatars, annotation actions, shortcut tooltips, cover hover, About page, theme paper, and general UI interactions.

Enabled type-aware linting, updated dependencies, extracted selection context utilities, migrated the deep runtime to AI SDK, and reduced duplicated runtime-boundary logic.
Removed the old focused co-reading flow and trimmed native module files from desktop packages to reduce release size.
Updated user docs, website download area, and third-party license lists so website version links match desktop open-source license information.
