  - Switch from MIT license to GPL-3
  - Update maintainer email, website URL, and GitHub URL.
  - Due to an error in the rail timing endpoint, the rail_times()
    function can only return example data for the time being. (#15)
  - Due to an error in the train position endpoint, the train_position()
    function can only return example data for the time being. (#16)
  - Add StopId column to bus_departs() and use current date in the
    example.

                 Changes in version 0.9.2 (2023-10-28)                  

  - Update to new package doc help page.
  - bus_schedule() now correctly merges both directions (thanks Prof.
    Moore!)
  - No longer calls unlist() on affected lines of length one.
  - Messages given instead of warnings when empty tibbles returned.
      - These conditions are tested with no_data_now() and
        mockr::with_mock().

                 Changes in version 0.9.1 (2021-03-01)                  

  - Covered most JSON endpoints as tidy data frames. Buses stops, train
    stations, next bus or trains, incidents, paths, routes, circuits.
    (#1)
  - httr::RETRY() in wmata_api() does not retry on 401, 404, etc. The
    purpose of this change is to primarily retry on 429 errors when too
    many requests have been made on a rate-limited subscription. Waiting
    should successfully retry.
  - Stops, Stations, Routes, and Lines saved as exported objects.
  - All functions accept api_key argument. (#5)
  - Calls are made using httr::RETRY() to deal with issues like rate
    limit. (#8)
  - Use the documentation and parameters in the official API
    documentation. (#7)
  - Convert all dates to POSIXct with UTC time zone.
  - Convert times to hms columns with values past midnight. (#6)
  - Removed parking_*() functions until a data frames can be made.
  - Removed rail_path() helper function. Keep only endpoint functions.
  - Removed ability to automatically scrape demo API key.
  - Removed package startup message about API key. (#2)
  - Invalid URLs are removed from function documentation.
