MAME 0.189 released

A new version of the arcade emulator MAME has been released. Here are the major changes in version 0.189:

The -sleep and -refreshspeed options have been fixed (MAME will no longer use 100% of a CPU core for the least demanding systems).
UI translations have been updated - Chinese, German and Greek are fully up-to-date.
Many layout and navigation bugs in the system/software selection menus have been fixed.
Slot card BIOS selection has been fixed.
Performance of machines that make heavy use of the output/artwork system has been substantially improved.
Support for many more PNG features has been added.
A number of issues with XML system/device output have been addressed.
