News LMMS Linux MultiMedia Studio [Freeware]

Linux MultiMedia Studio (LMMS) has been updated to version 0.4.8 for both Linux and Windows. Version 0.4.7 was released in August, adding the first x64 version.

LMMS 0.4.8 fixes most of the bugs found in version 0.4.7, the company says. The biggest change for the Win32 version is the full utilization of SSE and SSE2 instructions for all floating point math which makes it considerably faster. At the same time this means that the Win32 version of LMMS 0.4.8 will not run on old machines that do not support SSE and SSE2 instructions.
