It is mostly a bug fix release. However it brings support for several new local data such as Namibian Afrikaans, Tigrigina Eritrea, Amharic Ethiopia, Tajik Tajikistan, Kirghiz, and Farsi Iran. OpenOffice.org is now capable to format locale dependent information such as date and time in these languages.
Release 2.0.4 improves the integration with KDE, using now system wide parameters correctly. Apple OS X users will like the better integration of native fonts into applications.
Calc became a function “INFO” that allows to ask for system data and makes spreadsheets more compatible with Microsoft Excel. An improve HTML import makes is more likely for Calc to read HTML formatted tables correctly.
Impress got a new feature to save shapes as images directly from the context menu.
OpenOffice.org can now also import LaTeX formatted files. Also this release lays the ground work for OpenOffice.org extensions to be come popular and easier to manage.
And last but not least, OpenOffice.org release 2.0.4 is supposed to be wicked fast at start up.
I’ll report on my experience after I have used the new release a few days.
