# Changelog

## v2

- Preserve v1 as a separate package; this is a new package version.
- Correct `02_plot_fit_validation_v3.py` reference-line annotation from
  `axis="y"` to the public PlotSpec axis identifier `axis="left"`.
- Add all screenshots collected during the live tutorial execution.
- Document required Analysis Source aliases (`model`, `summary`).
- Document Dataset export/import across Sessions, including Metadata and Notes.
- Add the complete original source set from the preceding Python 3D terrain
  tutorial under `previous_3d_tutorial_sources/`.
- Keep the tutorial framework-native: numerical science uses `NUMERIC_API_v1`,
  data access uses `TABLE_STREAM_API_v3`, publication uses
  `DATASET_PUBLICATION_API_v2`, and plots use `PLOT_DATASET_API_v3`.
