Changes in version 0.1.0 (2026-10-30)                  

  - First release. Cell-wise rolling censor-and-redraw synthesis with
    CART leaf donors (raw strings copied), synthesised missingness, cell
    and row censor modes, lock groups for coupled columns, auxiliary
    predictors from other tables.
  - Every sheet of a workbook is synthesised into one output workbook;
    empty and small sheets are copied, blanked or dropped
    (small_sheets).
  - Identifier detection covers CDISC/EDC key names (USUBJID, SUBJID,
    SITEID, ...), multi-segment and zero-padded codes; identifiers and
    text columns can also be named or matched by pattern (id,
    id_pattern, text, text_pattern, or session-wide via
    options(cellsynth.id = ...)).
  - Very wide sheets (9,000+ columns) are screened block-wise in bounded
    memory.
