Changelog
What has changed on the archive that you would notice, newest first. Dates are UTC. New hours arrive every hour and are not listed here; this page is for new data, new pages, format changes and fixes to what we publish.
- New pages: /changelog, which lists what changes here, and /privacy, which says what this site records.
- The FAQ describes the per-client limit at the edge: up to 100 requests every 10 seconds from one IP address.
- The front page, quick start and uses page stop promising unlimited downloads, and the FAQ gained answers to questions sent through the feedback form.
- The V3 listing carries a coverage note above the list of venue incidents.
- Listings stay up while storage is busy: you get a recent copy of the page instead of an error.
- A light and dark switch on every page, a "Reading the files faster" section on /formats, and the download-change notice taken down.
- /witnesses charts rows delivered against rows merged for each machine, and its shares leave book snapshots out.
- Fixed: the feedback form could drop a message sent before the anti-spam check had finished. It now asks you to wait and send again.
- The Discord invitation also appears on /data-notes, the format pages and 404 pages.
- Each page has its own title and description in search results, and raw data files are kept out of search indexes.
- A dated notice on every page about where downloads are served from; /formats and llms.txt say where a script should fetch.
- Directory listings are also served under
/browse/, for example /browse/v3/. - Links to
.parquetfiles point at the direct-download host,dl.pendulumflow.com. - New contributed tier: devpyle's crypto Up-or-Down markets, 68 hours from 2026-08-15 to 2026-08-18, under
contrib/devpyle/with its own format page. - A feedback form, also on the front page, and an invitation to the community Discord.
