If you grew up listening to MP3s through Winamp in the early 2000s, there’s a good chance it still brings back memories. WACUP — short for WinAmp Community Update Project — is the community-driven effort keeping that classic experience alive, while quietly modernizing it in all the right ways. The latest release, 1.99.50.24496 Preview, arrived on May 8, 2026. It may not be a huge update on paper, but it fixes several annoying issues and shows the project is still being actively refined and improved.
