Changelog

Changelog

Every change to this site, generated from its git history rather than written by hand.

Updated

A site that tells people to signal freshness honestly should be able to show its own edit history. This page is generated from the repository's git log at build time, so it cannot drift from what actually shipped and cannot be quietly curated after the fact.

38 changes across 4 days of work, from 2026-09-17 to 2026-09-20. Source: git-committed. Short hashes refer to commits in the site's private repository.

One caveat worth stating rather than hiding: this data is generated immediately before each commit is made, so the very latest change — the one that published this version of the page — appears on the next update rather than this one. The list is complete up to the commit before the current deploy.
