Zotero 10.0

What's new in this version:

Redesigned advanced search:
- Now opens directly above the items list via a button in the quick-search bar and can filter any view, including collections and saved searches
- Supports nested condition groups for complex searches
- Allows choosing a result level — top-level items, attachments, annotations, or notes — with conditions automatically mapped across levels
- Terms in the quick-search bar automatically populate advanced search with equivalent conditions

New search conditions:
- Annotation Type, Color, and Author
- Attachment Storage Type
- of Annotations, # of Attachments, # of Notes, # of Tags
- New “is empty”/”is not empty” operators

Accent-insensitive searching and other search improvements:
- Searches now ignore accents and typographic characters (“cafe” ? “café”, “can't” ? “can’t”)
- Much faster full-text content searches
- Chinese, Japanese, and Korean searches in the quick-search bar now match full phrases, much more quickly
- Faster, more reliable indexing of new attachment content

Multi-collection selection:
- Select multiple collections, saved searches, or even libraries in the collections pane to view all of their items together
- View, search, and interact with items across libraries, grouped by library with sticky headers as you scroll
- Cmd/Ctrl-A in the collections pane expands the selection to all rows within the same parent

Batch editing:
- Edit fields on multiple items at once
- Combine with in-window advanced search and multi-collection selection to find and fix metadata across one or more libraries

Undo support:
- Undo and redo many operations using Edit ? Undo/Redo or standard keyboard shortcuts
- Plugins can opt their operations into undo history

Smarter Read Aloud:
- Better skipping of in-text citations, headers, footers, tables, figures, and equations
- Paragraphs are read continuously across columns and pages
- Individual sentences are now highlighted as they’re read, with word and paragraph highlighting options available in the settings
- Faster startup for large documents

Reading Mode for PDFs:
- View PDFs as clean, reflowable text with adjustable font, size, and line spacing — no headers, footers, or multi-column layouts
- Images, tables, and figures are shown as rendered in the original PDF
- Highlight, underline, and add notes in Reading Mode, with annotations and reading position shared with the standard PDF view

Improved Zotero Connector for Safari:
- Adds support for various features previously available only for other browsers, such as automatic proxy detection and redirection
- Requires Safari 18 on macOS 13 Ventura or later; older macOS versions keep the previous connector
