Security Vulnerability in Current Version 3.1.9398.500

Three or four weeks anyway. Maybe six one time in the last year or two (not days like for Firefox).

Maybe check the "beta" forum too if you're so inclined, which might get something a week or whatever earlier.

Since OpenOffice schedules updates about 4 times a year (like every 13 weeks) and every time there's that long wait here, I can't seriously depend on the Portable being current when I need it. If you use it at a place which frowns on poor security and maybe actively checks for and maybe blocks unpatched or obsolete softwear (like your workplace or library) you might think before starting to depend on this program, nice and handy as it otherwise would be. You risk being locked out of your documents at inconvenient times and places, or risk loss of privileges or worse if you use the old one in desperation.

My advice is to try to get them to install the standard version on their equipment now (before their stock answer becomes "use cloud computing instead"). The portable will always be handy at all those other places where they don't know or care who is running what.
