Hi,
For Windows users, the Win32 0.46pre4 has been updated to pre4-2 due to a missing file error. My apologies. You'll find pre4-2 on the Sourceforge server here; http://sourceforge.net/project/showfiles.php?group_id=93438&package_id=9...
This version is already quite stable, but please it for any further bugs and report to https://bugs.launchpad.net/inkscape/ If there are no other major problems, we will move to a stable release early next week.
Note, there are some known issues that won't be fixed for 0.46.0, as per the readme; * (LP: #180890) Blend modes do not work correctly over transparent backgrounds. A workaround is to place an opaque rectangle underneath the bottom-most layer. * (LP # 202704) Blur and other filters are very slow when applied to an object with transform= attribute with rotation or skew. To avoid this slowdown, either do not rotate/skew objects you use with filters, or apply filters only to paths (but not shapes to text) because paths, by default, get no transform= attribute when you rotate or skew them. * Windows printing has two known issues. In both cases the workaround is to print to bitmap (Print -> Rendering -> Bitmap). - (LP # 205732) Blurred objects are misaligned when printing. - (LP # 208217) Masked objects disappear when printing.
