zippeR 0.2.0 (2026-06-02)

UDS Mapper crosswalk data (2009–2022) is now bundled with the package, eliminating the runtime network dependency on an external GitHub repository
Partial support for 2024 TIGRIS year: zi_list_zctas() accepts 2024 in its valid range, and zi_get_geometry() accepts the argument but aborts with an informative message until internal data is rebuilt in a future release
Deprecated parameter aliases input_zip and dict in zi_crosswalk() with backwards-compatible support until early 2027
@examplesIf guards replace \donttest{}/\dontrun{} wrappers in all network-dependent and API-key-dependent examples
Minimum R version set to 4.1

Resolved several input validation gaps across zi_aggregate(), zi_crosswalk(), zi_convert(), zi_get_geometry(), zi_get_demographics(), zi_load_crosswalk(), zi_load_labels(), zi_load_labels_list(), zi_prep_hud(), zi_repair(), and zi_validate()
Fixed a number of incorrect column references, variable scoping errors, and unsafe dispatch patterns identified during a code quality audit
Replaced live Census API calls in tests with local fixtures so R CMD check passes on CRAN without a Census API key
Normalized non-standard column names in the 2015 UDS crosswalk

Dropped purrr, spatstat.univar, stringr, httr, readr, and tidyr from Imports
Added httr2 (>= 1.0.0) to Imports

Updates to README.md and NEWS.md to reflect the fact that the package is now on CRAN
Resolve R CMD check issue where examples in zi_crosswalk and zi_load_crosswalk fail on CI because a HUD key is not available to them
Fail informatively if tigris is not working due to U.S. Census Bureau servers being unavailable. At this time TigerWeb is not used as a backup due to the limited availability of ZCTA data

Initial CRAN submission version that contains functionality for working with UDS and HUD ZIP Code crosswalk files as well as Census Bureau ZCTA geometries and demographic data
