• Open files passed to Diff Anything by macOS and launch comparisons with two file paths. • Improved file-type detection compares files by their contents, even when their extension is misleading. • Clearer Pro offers explain what an upgrade adds to your current comparison, with better handling of long file names. • Improved command search, text editing and encoding labels. • CSV and environment-file comparisons use signs as well as color to identify changes. All comparisons remain private and local.

SCREEN READER WORKSPACE • A new workspace for VoiceOver opens automatically when a screen reader is running. It reads each difference as its location, its change and both values, and lets you step through, review and apply changes from the keyboard. • PDF, Word, PowerPoint and spreadsheet comparisons now describe their differences in words as well as on the page. MORE TO COMPARE • API schema comparisons show breaking-change verdicts and counts, and can gate a CI build from the command line. • YAML comparisons accept the same semantic rules as JSON. • Compare a CSV or TSV file with a workbook by cell values. • HTTP responses compare the version and reason phrase. CLEARER AND SAFER • Errors name the file and the side they are about, say which limit a large file is over and where to raise it, and appear above open dialogs. • A file that can no longer be read from disk marks its comparison as out of date instead of showing an old result as current. • A cancelled comparison is never reported as identical, and a three-way merge never invents a value when both sides change the same line. • A failed or cancelled folder synchronization says what was rolled back. • The toolbar, editor controls and source cards fit the window at the largest interface scale. • Hundreds of fixes across text, structured data, folders, archives, documents, images, the command line and Git integration. All comparisons remain private and local.

SMARTER CODE DIFFS • New Smart Diff understands code structure and highlights meaningful syntax changes. • Switch between Smart Diff and classic line-by-line comparison at any time. • Syntax highlighting now covers more than 100 languages, including 18 newly added languages. FASTER, CLEARER REVIEWS • Improved performance for large text files, folders and structured data. • Sharper difference navigation, status feedback, clipboard actions and error messages. • Better JSON, YAML, XML, environment-file and folder workflows. • Safer one-way apply, saving, folder synchronisation and recovery. QUALITY THROUGHOUT • Improved accessibility, stability, startup recovery and release security. • Expanded real-world test data and coverage across text, code, documents, archives, images, spreadsheets, folders, APIs and three-way merges. All comparisons remain private and local.

Version 1.4 expands archive comparison and makes complex merges easier: • Compare ZIP/ZIP64, 7z, RAR 1.3–7, TAR, Gzip, Bzip2, XZ and Zstandard archives. • Open multipart and solid 7z/RAR archives, including self-extracting files. • Compare password-protected ZIP, 7z and RAR files with separate, in-memory passwords for each side. • Stream large archives safely, with improved cancellation, extraction and protection against hostile inputs. • Improved three-way conflict resolution and folder comparison workflows. • Added editor theme refinements and reliability improvements.

Version 1.3.1 improves PDF comparison reliability and accuracy. • Fixed crashes and text-extraction failures in complex PDFs. • Improved visual diff regions so identical logos, footers and repeated content are no longer highlighted. • Added support for password-protected PDFs. • Hardened rendering for rotated, cropped, image-only, multilingual, form-based, unusually large and partially damaged documents. • Added safer failure handling across PDF, CSV, XML and structured-data comparisons.

Version 1.3 makes complex comparisons easier to understand and safer to act on. • Added three-way merge with Base, Ours and Theirs, automatic merging of independent edits, and clear conflict resolution. • Added reversible folder synchronisation with a reviewed plan, progress, rollback and one-click undo. • Upgraded PDF comparison with switchable rendered-page and extracted-text views. • Expanded image comparison with overlays, swipe, blink, pixel heatmaps and detailed difference metrics. • Improved spreadsheet, folder and document comparison. • Expanded syntax highlighting and automatic language detection across developer formats. • Added command-line, Git difftool and batch workflows with HTML, JSON, CSV, JUnit and SARIF reports. • Improved accessibility, performance and reliability throughout.

Diff Anything 1.2 makes comparison and merging more capable, consistent, and reliable. • Added three-way merge and safer, reversible folder synchronization. • Added richer document and image comparison, including PDF page previews and pixel heatmaps. • Expanded syntax highlighting and automatic language detection across many developer formats. • Added command-line and batch workflows for repeatable comparisons and reports. • Improved accessibility, performance, and reliability throughout the app.

Version 1.1 brings powerful new workflows and major comparison upgrades: • Resolve conflicts in a new interactive three-way merge workspace. • Synchronize folders safely with clear create, update, and delete plans, automatic rollback, and one-click undo. • Inspect images with overlay, swipe, blink, heatmap, difference masks, true-pixel zoom, and improved metrics. • Navigate richer PDF and Office document comparisons. • Enjoy improved syntax highlighting and language detection across more development languages and frameworks. • Use the enhanced CLI with syntax-highlighted terminal output and Git difftool integration. • Benefit from accessibility, stability, and performance improvements throughout the app. Your comparisons stay private and local on your Mac.
