On a.m. URL for Extension "LibreOffice Server Installation GUI 3.0" under Heading "Release Notes" you see my addition "It's recommended to uninstall old versions ...", what's difficult to read because space left of the table is too arrow. I think that text should appear below the table. Minor problem because of easy workaround with some linefeeds before text starts (see <http://extensions.libreoffice.org/extension-center/languagetool/releases/2.0>
I can confirm this and it'll be indeed much better to place the text under the table.
Page changed, we're now in 4.0.2. Everything seems readable now (IMHO! :-)) I put it as WFM but don't hesitate to reopen this tracker if I missed something.
