Changes in version 0.2.0 (2026-10-15)                  

  - sage_columns() now reads Parquet schemas through Arrow's
    random-access GCS reader when the source is the public bucket and
    the installed arrow has GCS support compiled in, instead of
    downloading six whole partitions (about 298 MB) to inspect their
    schemas. Roughly a 2-4x speedup on a cold cache. The full-download
    path remains as a fallback, so builds of arrow without a cloud
    filesystem behave exactly as before (thanks, @dshkol, #118).

  - A trailing slash on a remote source ("gs://sage-archive/parquet/")
    no longer produces a doubled separator and a missing-object error.
    Remote sources are normalized once, in .sage_source().

  - http://storage.googleapis.com/... sources take the same fast path as
    https:// ones.

  - The package now ships a small offline excerpt of the archive
    (Iceland and Samoa, 26 KB) under extdata/mini_archive, so every
    example runs without network access.

  - Failure to read the archive index now reports which source was tried
    and whether the likely cause is an unreachable remote.

  - Added documentation for all exported functions, a test suite, and a
    LICENSE file.

                        Changes in version 0.1.0                        

  - First release: sage_load(), sage_countries(), sage_years(),
    sage_columns(), sage_polygons(), sage_preference_votes(), and
    sage_set_source().
