KMSCON 10.0.2 was released, adding support for playing asciicast recordings and fixing bugs.
The new playback feature lets developers record and replay terminal sessions without external tools, aiding debugging and demonstrations. Because KMSCON runs in user space on top of Linux's KMS/DRM interfaces, the update strengthens the most viable alternative to in-kernel virtual terminals, and the bug fixes reduce crashes or rendering issues.

THE READ
What the cluster adds up to.
KMSCON is a user-space terminal emulator built around Linux's KMS/DRM interfaces and is positioned as a leading alternative to in-kernel virtual terminals. The 10.0.2 release marks the latest update to this component. Its design means it runs alongside the kernel graphics stack rather than inside the kernel itself.
The most visible change in 10.0.2 is the addition of asciicast playback support. This feature enables the emulator to replay terminal session recordings that were captured in the asciicast format. Engineers can use this capability to review command-line interactions for debugging or instructional purposes without needing separate playback tools.
Alongside the new playback feature, the release bundles a set of bug fixes. These fixes aim to improve the reliability of the emulator, reducing the likelihood of crashes or rendering glitches during normal use. Updating to 10.0.2 therefore offers a more stable experience for existing deployments.
Adopting the update typically involves installing the new package from the distribution's repositories, with no major configuration changes required. The emulator continues to depend on the presence of KMS/DRM interfaces, so it will not function on systems that lack those graphics subsystems or on non-Linux platforms. Additionally, playback is limited to the asciicast format; other recording formats remain unsupported.
