Changes in version 0.1.0 (2026-06-08)                  

  - Initial CRAN release.
  - Core API: auto_mutate(), auto_summarise(), auto_filter() wrap dplyr
    verbs and register variable metadata (type, source columns,
    categories, source code) automatically.
  - Manual registration via cb_register(); codebook accessors via
    cb_get(), cb_reset(), cb_render(), cb_export() (HTML, CSV, DOCX,
    XLSX).
  - Eligibility tracking: track_step(), track_get(), track_render(),
    track_export().
  - CONSORT-style flow tree: track_split(), track_outcomes(),
    flow_table(), flow_get(), flow_reset().
  - flow_diagram() draws a publication-ready CONSORT-style flowchart (a
    ggplot object) from the captured eligibility steps and the flow
    tree: a vertical trunk (cohort baseline, aggregated exclusions box,
    eligible cohort), one column per subgroup, and outcome boxes stacked
    beneath each subgroup. The standardized report embeds it
    automatically.
  - flow_diagram_export() saves that flowchart by file extension: raster
    (.png, .jpg, .tiff), vector (.pdf, .svg, .eps), an .emf metafile
    editable in Word, a .docx document with the flowchart embedded as a
    vector image, or a .pptx slide whose boxes and labels are fully
    editable PowerPoint shapes. generate_report() now also writes
    flowchart.docx alongside the report.
  - Big-data optimizations for sparklyr (tbl_spark): cb_checkpoint(),
    per-call cache and assume_unique, session defaults via
    cb_set_verbose() and cb_set_default_cache().
  - Standardized HTML report via generate_report(), with eligibility
    flowchart, editable codebook export, and cross-sectional or
    longitudinal variable inspection.
