A missing year does not mean the conference did not meet: coverage before 2008 has not been verified.

Extensions: strict in 2025-2026

Kept verbatim from the old site while it is being turned into structured data.

Data entirely hand-typed, one call for papers at a time. There is no scraper behind any of this: I read the announcement and type the dates in, in the gaps between other work, and with the hope it is useful to others. Organisers then move deadlines without telling anyone, calls get edited in place, and now and then the typing is simply wrong. Treat this as a well-meaning notebook rather than an authority, and check the conference’s own page before you submit anything you care about.
