Regolith R1.4.1 is a fast follow up to 1.4 that fixes a few serious bugs, detailed on the mailing list. In addition to the package updates, a new boot animation is provided by the package plymouth-theme-regolith that is installed by default on the ISO. The ISO also now excludes a deprecated touchpad driver that was conflicting with Settings. Existing PPA-based installations can simply get the updates via their typical package update process. Regolith Linux ISO users can update to R1.4.1 by applying regular package updates.
