After four months of development, it's time for the next big OpenMPT release, and OpenMPT 1.25 brings a great bunch of new and improved features.
The biggest change is probably that there is now a third flavour of OpenMPT: The default 32-bit builds are now optimized using the SSE2 instruction set and require Windows 7 or later to run. Older operating systems and CPUs without SSE2 are still supported through a separate build. The 32-bit OpenMPT installer contains both builds and chooses the most suitable one for you. When using the zip package, you will have to pick the correct version on your own. The 64-bit package requires Windows 7 as well, so on 64-bit Windows XP and Vista, it might not work as intended and you will have to resort to using the 32-bit version for now. This might change if a great need for a legacy 64-bit version arises, but we currently doubt that this is the case.
For more information, there is a forum post about the different OpenMPT configurations.
Here is a short summary of the most notable new features:
