“After a release cycle that was unusual in so many (bad) ways, this last week was really pleasant. Quiet and small, and no last-minutepanics, just small fixes for various issues. I never got a feeling that I’d need to extend things by yet another week, and 4.15 looks fine to me.“, Linus Torvalds announced.

What’s new in Kernel 4.15:

  • support for the RISC-V architecture
  • support for AMD Secure Encrypted Virtualization

Last updated: January 27, 2018

StepMania icon

StepMania, free dance and rhythm game, reached first beta of new major 5.1 series a day ago.

“Due to the amount of remaining work needed, the scope of changes, and in response to feedback about difficulty with new systems: StepMania 5.1 is now going to be postponed to 5.2, and to bring some of 5.2’s less invasive and more demanded features to people we’re going to be backporting things onto 5.0 for version 5.1.”

Features planned for 5.1 include:

  • Loading songs from profiles on USB drives
  • PacDrive support
  • Updated default theme
  • Profile improvements (including switching stats XML to an SQLite database)
  • Mouse support for all platforms (may not be used in the default theme – but available for others)
  • Stencil-based masking by default instead of zbuffer masking, so masking 3D objects behaves better without resorting to render to texture.

As the first beta release it brings following changes:

  • A new high-resolution (720P) default theme: Lambda
  • The DirectInput handler for Windows now supports XInput.
  • Songs can be loaded from profiles on USB drives.(For Linux, StepMania must run as root to save USB profile scores)
  • And many other changes, see release page for details.
