Maintained geometry

The generator preserves the original detailed arrows and labels, extends active system bars and the time axis, and normalizes fonts for stable local rendering.

Refreshable versions

Release labels live separately from chart geometry. FreeBSD, NetBSD, OpenBSD, Darwin, macOS, GNU/Hurd, Minix, Linux, and Solaris can be refreshed without redrawing the lineage.
