== Features ==

Gadu-Gadu uses its own proprietary protocol. As with [[ICQ]], users are identified by unique serial numbers. Protocol's features include [[status message]]s, [[file sharing]], and [[VoIP]]. Users may [[formatted text|format]] and embed images in messages. Starting from client version 6.0, an experimental feature utilizing a secure [[Secure Sockets Layer|SSL]] connection was introduced, although it remained inactive until the beta release of version 10.0.<ref>{{Cite web |last=Ponikowski |first=Mateusz |title=Szyfrowanie w Gadu-Gadu 10 |url=https://www.instalki.pl/aktualnosci/software/3511-szyfrowanie-w-gadu-gadu-10.html |access-date=2023-05-15 |website=www.instalki.pl |date=29 March 2010 |language=pl-pl}}</ref>

The official client provides over 150 [[emoticons]], allows grouping contacts, sending [[SMS]] and integrates with other services run by the same company: a virtual Internet dial-up, a [[social networking]] site MojaGeneracja.pl (defunct since 5 November 2012) and an [[internet radio]] Open.fm.{{Citation needed|date=June 2022}}

On February 9, 2009, a significant new major version of the application, named ''Nowe Gadu-Gadu'' (which translates to "New Gadu-Gadu" in Polish), was released. The [[graphical user interface]] underwent a complete overhaul, being rebuilt from scratch using the [[Qt (software)|Qt framework]]. This update brought along a range of notable enhancements, including the introduction of [[voice calling]] capabilities, a [[spell checker]], an anti-[[Spamming|spam]] filter, the ability to display [[YouTube]] 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.<ref>{{Cite web |date=2009-02-09 |title=Rewolucja w komunikatorze Gadu-Gadu! |url=https://www.chip.pl/2009/02/rewolucja-w-komunikatorze-gadu-gadu |access-date=2023-05-15 |website=CHIP - Technologie mamy we krwi! |language=pl}}</ref>
