I've just posted a pre-release of OpenOffice.org Portable 2.4. This new release updates OpenOffice.org to 2.4. As this is a larger point release for OpenOffice.org, we're running a pre-release first to ensure both new installs and upgrades work properly (rather than being irresponsible and just rushing it out for the sake of having it done quickly.)

One thing I'm debating is whether or not to remove the Vera fonts from upgrades. Vera used to be included but OpenOffice.org now includes a set of DejaVu fonts. The OpenOffice.org installer (and uninstaller) leaves the Vera fonts installed on Windows, so at the moment, I'm leaving them intact in case someone used them for existing files. They only take up 564k so it isn't a huge deal comparatively. The new DejaVu fonts are, unfortunately, much larger at 6.9MB.
As OpenOffice.org Portable's install size is now up to 258MB 240MB (as of PR2), I'm debating doing a minimal version called OpenOffice.org Portable Light. By leaving out all the optional bits (UNO-Python, Help Files, Fonts, etc) and stripping out the non-English dictionaries it can be trimmed down to 143MB 110MB (after some further adjustments) while still maintaining full functionality. We'd probably only do this for English (our primary supported language and the most popular worldwide). I'd be up for any thoughts on this.
Please test and post your findings, thanks...
