the new version of the app would integrate with newer music platforms such as Apple Music and Spotify. On other platforms Android Winamp for Android is a mobile version for the Android (version 2.1) operating system, released in beta in October 2010 with a stable release in December 2010. It includes syncing with Winamp desktop (ver. 5.59 beta+) over USB or Wi-Fi. It was received with some enthusiasm in the consumer blog press. The app was removed from the Play Store in 2014. It was reported by TechCrunch that a redesigned Android app was planned alongside the announcement of the development of Winamp 6. Macintosh In 1997 Nullsoft also released MacAmp, an Apple Macintosh equivalent of Winamp. In October 2011, Winamp Sync for Mac was introduced as a beta release. It is the first Winamp version for the Mac OS X platform and runs under version 10.6 and above. Its focus is on syncing the Winamp Library to Winamp for Android and the iTunes Music Library (hence the name, "Winamp Sync for Mac"). Nonetheless, a full Winamp Library and player features are included. The developer's blog stated that the Winamp Sync for Mac Beta would pave the way for future Winamp-related development on Mac and a fully featured media player as Winamp on Windows. However no further development occurred. Linux An early alpha preview of Winamp3 for desktop Linux was developed in October 2001, but the project was not pursued. Nonetheless some versions of Winamp for Windows are functional using Wine. MS-DOS DOSamp for MS-DOS operating systems was released in 1997. The software was soon abandoned by Nullsoft to focus on the Windows version (Winamp). Easter eggs Winamp has historically included a number of Easter eggs: hidden features that are accessible via undocumented operations. One example is an image of Justin Frankel, one of Winamp's original authors, hidden in Winamp's About dialog box. The included Easter eggs have changed with versions of Winamp, and over thirty have been documented elsewhere. Derivative works Unagi is the codename for the media playback engine derived from Winamp core technologies. AOL announced in 2004 that Unagi would be incorporated into AOL Media Player (AMP), in development. After beta testing, AMP was discontinued in 2005, but portions lived on in AOL's Web-based player. An HTML5 and JavaScript-based web player resembling the graphical user interface of Winamp 2 has been developed. See also MacAmp Audacious XMMS
