It seems as if Toni Wilen, developer of WinUAE never rests as even today on a Sunday he's just released the latest Amiga emulator beta version of WinUAE 2.9.0 beta 25. A version which again contains even more bug fixes such as uaenet.device + slirp combination was broken (probably has always been) and more accurate 68000 prefetch mode instruction cycle usage. So if you want the latest release, read the changelog and grab the download link.
