# Version 2026.7.2

- **Breaking:** dropped support for the 2020 border year. All `_b2020` datasets are removed and every data-returning function now accepts only `border = 2024` (`set_config(border_nor = 2020)` and `border = 2020` now error). Use `border = 2024`.
- Population data now carries a sex dimension. `nor_population_by_age_b2024` includes real `male`/`female`/`total` splits (fetched from SSB tables 07459 and 10826 with `Kjonn = TRUE`). Locations where Statistics Norway provides no sex breakdown (Svalbard, Jan Mayen, unknown) carry `total` with `NA` male/female.
- New exported function `nor_population_by_sex_age_cats()` returns population by custom age categories split by sex, with `include_total_age` and `include_total_sex` toggles.
- `nor_population_by_age_cats()` is unchanged for callers: it now filters to `sex == "total"` internally, so its output remains identical (total only).
- Note: at redistricted sub-national levels each sex is rounded independently, so `male + female` may differ from `total` by up to 3 people in ~0.6% of historical cells (exact at the national level).

# Version 2026.3.30
