Starting from client version 6.0, an experimental feature utilizing a secureSSL connection was introduced, although it remained inactive until the beta release of version 10.0.[4]
The official client provides over 150emoticons, allows grouping contacts, sendingSMS, and integrates with other services run by the same company, such as the internet radio Open.fm and the social networking site MojaGeneracja.pl (defunct since 5 November 2012).[5][6][7]
On February 9, 2009, a significant new major version of the application, namedNowe Gadu-Gadu (which translates to "New Gadu-Gadu" in Polish), was released. Thegraphical user interface underwent a complete overhaul, being rebuilt from scratch using theQt framework. This update brought along a range of notable enhancements, including the introduction ofvoice calling capabilities, aspell checker, an anti-spam filter, the ability to displayYouTube videos directly within the chat window as embeds, customizable skins, the addition of tabs, and several other additions aimed at improving the user experience and security.[8]
