LibreOffice 4.0 ALPHA 1 released (Ubuntu 13.04 to feature the 4.x series)

Editing thousand-pages long documents, creating presentations for a certain public event, managing spreadsheets, etc, are actions that can be easily satisfied in Ubuntu via LibreOffice, a powerful versatile office suite.

Along with an impressive number of features, it seems that LibreOffice is a project constantly enriched, refined, improved and strengthened, constantly seeing new releases (characterized by solid functionalities, care for stability, etc).

LibreOffice 4.0 ALPHA 1 has been released, marking the first release from the 4.x series.

Various under-the-hood enhancements, as well as interesting additions (such as the landing of Impress Remote, accessible under Impress-->Slide Show-->Impress Remote) come to encompass the newly released LibreOffice 4.0 ALPHA 1.

Ubuntu 13.04 is to receive the 4.x LibreOffice, according to Ubuntu's Bjoern Michaelsen, "Libreoffice 4 will be in Raring Ringtail".
