After 0.1.4 and 0.1.5 with minor bugfixes, 0.2.0 is a major rewrite in Eclipse using SWT instead of AWT. This removes some of the most uncomfortable shortcomings in the UI, like absolute positioning in the transaction-compose window.
The binary can be used in Linux and Windows (r)(tm), for other operating systems that support both SWT and OpenOffice.org, like Solaris, it should be fairly easy to run by adding the corresponding SWT classes and libraries.
0.1.5 I already called Windows-compatible, nevertheless, a small bug-fix now also allows OpenOffice.org to be installed in a path with a space, e.g. '\program files\openoffice.org 2\'.
I do not consider 0.2.0 to be ready for productional use but it marks the milestone where the proof-of-concept evolves into an actual alpha version.
