DEVONthink To Go 4

This maintenance update introduces support for Nano Banana Pro (Preview) and DeepSeek 3.2, and updates support for, e.g., Gemini, Claude Opus, Mistral, and many more providers and models, both via OpenRouter and local. The Settings popover dynamically adjusts to the actual screen size, and tag suggestions draw from all databases. Opening external item links works again, global smart groups are sorted correctly, and we've fixed EPUB dark mode. The sync settings prevent editing Bonjour locations while they are offline.

This maintenance update improves the search syntax, custom metadata handling, and the overall reliability. It also fixes issues with favorites, PDFs, the Summary popover, smart groups, syncing, and licensing, while making the app generally more stable and less prone to freezes.

DEVONthink To Go now supports RSS feeds including automatic updating in the background. Home screen widgets give you quick access to inbox counts, unread RSS items, top reading list entries, your most-used favorites, and recently viewed documents. A brand-new Markdown renderer replaces MultiMarkdown 6 and delivers more reliable previews and broader syntax support. DEVONthink To Go also adds support for BibTeX documents, and you can now merge multiple images into a single PDF document. Other improvements include the option to open certain documents directly in editing mode, an enhanced group selector, and new actions for geolocations in the "Info" popover. * We're naming this release after the mathematician Joseph-Louis Lagrange (1736–1813) who made significant contributions to the fields of analysis, number theory, and both classical and celestial mechanics. Lagrange's work has had a profound impact on our understanding of celestial mechanics and has practical applications in space exploration.

This maintenance release improves database verification and repair. Creating new documents without giving them a title now uses a unified generic name. The update also addresses several issues, including broken sharing to third-party apps and a vanishing sidebar button.

This maintenance release adds emergency notification support so we can reach you quickly if a critical fix is held up for some reason. It also fixes a range of issues, including ones related to item counting, wrong RSS article dates, and non-functioning chat exclusion controls.

This maintenance release gives the integrated help pages a visual overhaul and resolves a number of issues, including a crash in the chat, UI delays, and deadlocks. It also fixes unformatted dates in feed articles and syncing bundle documents.

This release introduces Zen mode for distraction-free reading and editing, a redesigned icon view, and an updated OCR engine with improved accuracy and language support. Create new images or edit existing pictures with the new AI image creation popover, and add notes or scan documents right from the Control Center. Quickly navigate your databases with your favorites right on the databases list. Color groups and tags — all synchronized with the Mac — and order documents manually if needed. The chat can highlight text passages and ignores documents from databases you exclude. NOTE: We're naming this release after the Chandra X-ray Observatory, NASA's flagship X-ray telescope launched in 1999 and itself named after the astrophysicist Subrahmanyan Chandrasekhar (1910–1995). Chandrasekhar determined the mass limit above which a white dwarf star cannot support itself against gravitational collapse, laying the groundwork for our understanding of neutron stars and black holes. His work reminds us that perseverance can reveal truths about the universe even long before anyone has the means to observe them.

This maintenance release focuses on stability and performance. Item counting is faster and sync downloads data more quickly by matching the Mac's concurrent connection count. We have also fixed a range of crashes and smaller issues.
