Changelog

jpstat 0.5.0

collect() methods for estat objects are now documented, including the previously undocumented n, names_sep, query, and limit arguments.
collect() no longer reports the total number of records with print(); it now uses cli::cli_inform() so the message can be suppressed with suppressMessages().
estat() now uses HTTPS for the ‘e-Stat’ API endpoint.
The deprecated appId argument to estat() has been removed. Use Sys.setenv(ESTAT_API_KEY = ) instead.
estat() and collect() now automatically retry ‘e-Stat’ API requests on transient network failures.
Errors raised by estat() and collect() are now classed (e.g. jpstat_error_estat_api, jpstat_error_estat_missing_key) so they can be caught programmatically.
estat_table_info() is now defunct. Use summary() instead.
The ‘RESAS’ API was discontinued on 2025-03-24. resas() is now defunct and errors when called.
webland_trade() and webland_city() have been removed. The “Land General Information System” API they used was discontinued, and its replacement, the Real Estate Information Library API, does not expose metadata for navigatr’s menu interface, so jpstat now focuses solely on the ‘e-Stat’ API.
