2026-08-08
Fix: Canceling a directory comparison's background content comparison (Esc) could take a very long time when many files required plug-ins
Fix: Clicking Cancel or pressing Esc during a comparison or plug-in execution often didn't register on the first attempt
Fix: Background content comparison in tree mode of directory comparison could run much slower than expected on large comparisons
Fix: Starting a new comparison shortly after canceling a directory comparison's background content comparison could crash the application
Fix: Canceling a comparison could leave a plug-in's helper process (e.g. when comparing against a remote URL) still running in the background
Fix: Comparing a password-protected ZIP, 7z, RAR, or other archive file could leave the application unresponsive indefinitely instead of showing an error
Fix: Comparing certain RTF files using the DOC to Text plug-in could incorrectly show them as identical, or show missing content
Fix: Comparing certain RTF files using the DOC to Text plug-in could show extra blank lines not present in the original document
2026-07-17
Improvement: Much faster results filling when comparing directories with a very large number of files in list mode
Improvement: Much faster background full content comparison when comparing a very large number of files
Improvement: Faster, more responsive text selection when dragging the mouse in large or complex files
Fix: Statistics chart's title, legend, and labels could crowd out the pie chart itself on displays with Windows scaling above 100%
Fix: In tree mode of directory comparison, expanding or collapsing an item while background content comparison was running could crash the application
Fix: In tree mode of directory comparison, clicking or scrolling while background content comparison was running could significantly slow down both the UI and the comparison itself
Fix: Moving the cursor with the Up, Down, Page Up, or Page Down keys did not update the Line Inspector
Fix: Clicking inside an existing text selection, then extending it with Shift and an arrow key, could extend from the wrong starting point
2026-07-12
Improvement: Updated 7-Zip plug-in to the latest version 26.02
Fix: In directory comparison, line counts for added and deleted files included ignored lines, inconsistent with counts for changed files
Fix: Generating an HTML report from the command line could hang indefinitely or consume excessive memory on large or complex files, since syntax highlighting had no time limit outside the interactive UI
Fix: In directory comparison, files could incorrectly show as identical when full/parallel content comparison ran out of memory
Fix: Canceling a directory comparison's background content comparison (Esc) could hang or fail to stop it
Fix: Some binary files (e.g. compressed media) were misidentified as text, causing slow or excessive-memory comparisons
Fix: HTML diff reports (including directory comparison) used a much larger font and row/column sizing than the app itself on displays with Windows scaling above 100%
Fix: In tree mode of directory comparison, the diff bar could fail to show a difference block when it started on an item hidden under a collapsed parent folder
2026-06-30
Improvement: Cleaner "Explorer Menu" submenu, with duplicate entries from other shell extensions removed
Improvement: Pane splitters in text comparison and merge now resize panes live while dragging when Windows' "Show window contents while dragging" setting is on, instead of only after releasing the mouse
Fix: ExamDiff Pro context menu did not appear in Total Commander, Everything, and other third-party file managers on Windows 11
Fix: Line Inspector could show a stray gray square when first displayed in merge mode
Fix: In directory comparison, the color codes bar was slightly misaligned with the scrollbar at the bottom of long lists
2026-06-20
Improvement: Status bar now shows the number of selected characters and the Unicode code point of the character at the cursor
Fix: ExamDiff Pro was missing from Windows 11 modern right-click context menu (broken in build 17.0.0.8)
Fix: Binary comparison HTML report displayed line breaks instead of dots in the ASCII column for control characters
Fix: File comparison line count statistics included ignored blank lines, causing inconsistency with directory comparison "# of Diffs" count
