Avalanche: Convenient GUI for the XADMaster.library, a library that allows you to unpack all common native Amiga compression formats like LHA and LZX or other platforms like ZIP, 7zip, Bz2, GZ, TAR.GZ.
Avalanche makes use of ReAction for OS 3.2 so unless you specifically "upgrade OS 3.2 libraries" it cannot work on OS 3.9 or lower.
