For Inkscape 0.48.1, two Windows builds are available:
a) 0.48.1-2 with cairo 1.8.8 (recommended):
Inkscape-0.48.1-2.exe (installer)
inkscape-0.48.1-2-win32.7z (archive with program folder)
inkscape-0.48.1-2-win32.zip (archive with program folder)
inkscape-0.48.1-2-win32-debug.7z (debug symbols)
InkscapePortable_0.48.1.paf.exe (portable)
b) 0.48.1-1 with cairo 1.10.2:
Due to a minor regression (some GUI elements - layer icons, text widgets in the filter editor - don't display correctly [1]) this build is not recommended for general use unless the most recent stable cairo release (1.10.2) is required for PDF/PS/EPS export:
Inkscape-0.48.1-1.exe (installer)
inkscape-0.48.1-1-win32.7z (archive with program folder)
inkscape-0.48.1-1-win32.zip (archive with program folder)
inkscape-0.48.1-1-win32-debug.7z (debug symbols)
InkscapePortable_0.48.1-1-do-not-use.paf.exe (portable)
