Changes in version 0.2.1                        

REST API

  - serve() starts a plumber REST API over get_census(),
    get_population(), get_census_boundaries(), census_languages(),
    census_sc_st(), the variable listings and every shipped dataset.
    Responses are paged, geometry comes back as GeoJSON, and each
    request is logged with the kind of client that made it.

New data

  - census_1931_castes: population of every caste in the 1931 Census
    caste tables by religion, for 24 provinces, states and agencies.
  - census_1931_exterior_castes: castes the 1931 Census treated as
    exterior, by province section of Appendix I.

Data fixes

  - census_subdistricts_2011 covers every Census 2011 subdistrict and
    sums to census_2011_pca. It had listed current subdistricts, with
    Telangana, Delhi, Puducherry and Ladakh NA.
  - census_1971 and census_1981 record an empty rural or urban sector
    as 0.
  - population_projections_district_age(),
    population_projections_district_lgd_age() and
    population_projections_district_lgd have no NA. Theni 2017-2031,
    printed with Madurai's numbers, follows Tamil Nadu's common growth
    path. Moga and Tapi's unprinted 80+ for 2022-2026 is All ages minus
    the other groups. Both age tables download again on first use.

                        Changes in version 0.2.0                        

  - First CRAN release.

Breaking changes

  - Census boundaries and seven large tables are no longer installed
    with the package. They are downloaded on first use, checked against
    a pinned MD5 checksum and cached in census_cache_dir();
    clear_census_cache() removes them. The tables are now functions, so
    census_2011_workers becomes census_2011_workers(). The same applies
    to census_2011_demographics(), census_2011_marginal_detail(),
    census_2011_mother_tongue(), census_2011_subdistrict_languages(),
    population_projections_district_age() and
    population_projections_district_lgd_age().

Other changes

  - census_download() fetches every remote file at once, with a progress
    bar. Checksums and version directories live in inst/manifest.csv.
  - clear_geometry_cache() also releases downloaded tables held in
    memory.
  - plot_map() now reports a failed boundary download instead of drawing
    the map without its base layer.
  - at_level() documents and accepts any table with a level column,
    including census_1981.

                        Changes in version 0.1.2                        

  - Population projection tables checked cell by cell against the
    printed MoHFW and IIPS reports.
  - Boundary files shipped gzipped.
