DataFrame support is not going ahead, so the pages documenting it come out: the relational operations and the expression system, both of which described only that API. The manual was framed around having two query surfaces and choosing between them. With one, that framing is gone — the overview now leads with SQL over Arrow Flight SQL and what the dialect is, rather than with a comparison to something that will not exist. The function reference keeps everything that was about SQL: the DataFusion version, how Lance columns map onto its type system, the pseudo-columns, blob handling, and `fts()`. Only the section on reaching functions through the Python wrapper is replaced, since the wrapper is going too. Mentions of pandas and polars DataFrames elsewhere in the documentation are unrelated and untouched.
