Socialtext, which specializes in enterprise-level, web-based collaboration technologies, such as its eponymous flagship service, has upgraded to version 4.4, offering improved features and an overhauled search engine. Search queries are now returned quicker across multiple workstations with increased accuracy, in addition to other changes such as the 500-page result limit being removed. Sharing has also become simpler with the inclusion of a "Signal This!" button on workspace pages, which allows for the quick sharing of links to whatever groups are specified. Finally, attachment management has been streamlined and is now more intuitive.
