* Preferences entry for changing the default operator to concatenate query terms (OR vs. AND).

* Non-lethal crash while parsing Excel files in the old Excel format (BIFF5 from Excel 5.0/7.0).
* The CHM parser could crash with a stack overflow; also, it omitted text in CHM files that had a particular format.
* If one of the parsers crashes badly, the user is asked to send the problematic file to
docfetcher@users.sourceforge.net for debugging (bug #2948903 and #2944552).
* Indexing-related crash that shows a "ThreadInterruptedException" (bug #2971390 and #2953613).
* Crash on older Windows versions where no graphics library (GDI+) is installed (temporary fix for bug #2943966).
* Crash if the user clicks on the column header "Author" (bug #2956392).
* Crash if the user lets DocFetcher index itself and then selects "List Documents" on the created index.
* Fixed some minor errors in the manual.
* Fixed some errors in the French GUI translation.
