zippeR 0.2.0

New features and improvements

• 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

Bug fixes

• 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

Dependency changes

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

zippeR 0.1.2

• Address issues with Census Bureau API being offline

zippeR 0.1.1

• 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

zippeR 0.1.0

• 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
