The clock shows the date without the time of day. Elasticity drops from 0.3 to 0.1 so the tree sways less through large refactors. Captions come from the git tags and a tracked milestones file with a milestone per component and service at the commit that introduced it, plus growth markers (commit counts, 50k-line steps, issue and PR id doublings). --record writes gource-hyperhive.webm, AV1 in WebM through SVT-AV1, instead of a near-lossless H.264 file. --help (or -h) lists the flags; an unknown argument prints it on stderr and exits 2.
