Versioning and Upgrades

Current documentation version: WolfXL 2.1.0

The API reference and getting-started guides on this site describe WolfXL 2.1.0. WolfXL 2.0 is a separate historical release.

What changed in 2.1

WolfXL 2.1 adds three major public API groups:

  • Calculation: native-first formula recalculation, dynamic-array formulas, cross-sheet dependency handling, dependency inspection, and typed diagnostics.
  • Rendering: workbook and worksheet PDF, sheet and range PNG or PDF, and chart PNG, PDF, JPEG, or SVG output.
  • Conversion: bounded conversion workflows for XLSX, ODS, XLSB, XLS, PDF, PNG, HTML, TXT, CSV, and TSV, with explicit preservation and loss reporting.

The detailed method signatures and supported boundaries live in the linked WolfXL 2.1 API sections.

Upgrade from 2.0

Existing Developer credentials continue to use the same authenticated private index. No credential change is required.

python -m pip install --upgrade wolfxl --index-url https://packages.wolfxl.com/simple/
python -c "import wolfxl; print(wolfxl.__version__)"

The version check should print 2.1.0.
