v0.4.2 (June 19, 2019)

This is a minor release from 0.4.1. We recommend that all users update
to maintain compatibility with IEX Cloud and optimize message weighting
in calls.

Highlights:

  • Removes support for the legacy Version 1.0 IEX Developer API, which
    was retired in favor of IEX Cloud in June 2019
  • Optimized retrieval of historical prices with get_historical_data
    to allow for close prices only and single day charts to reduce
    message counts
  • Add support for End of Day options prices

New Endpoints

Options

  • End of Day Options (get_eod_options)

Data APIs

  • /time-series (get_time_series)
  • /data-points (get_data_points)

Enhancements

  • Adds logging for queries, including message count usage and
    debugging information. Logging level defaults to WARNING, but can
    be set to other levels through the IEX_LOG_LEVEL environment
    variable. The following levels provide various information:

    • WARNING - errors only
    • INFO - message count used
    • DEBUG - request information

  • Add close_only keyword argument to get_historical_data to allow
    for retrieval of adjusted close only at reduced message cost
    (through chartCloseOnly query parameter)

  • Optimize get_historical_data to use chartByDay if a single date
    is passed which reduces message count (thanks shlomikushchi)

Backwards Incompatible Changes

  • When IEX_API_VERSION is set to v1, IEX Cloud will now be used,
    and as such this has the same behavior as iexcloud-v1

  • The following legacy-only endpoints have been deprecated and will
    raise an ImmediateDeprecationError when called:

    • iexfinance.stocks.get_crypto_quotes
    • iexfinance.refdata.get_iex_corporate_actions
    • iexfinance.refdata.get_iex_dividends
    • iexfinance.refdata.get_iex_next_day_ex_date
    • iexfinance.refdata.get_listed_symbol_dir
    • iexfinance.stocks.Stock.get_effective_spread

  • The get_all method of iexfinance.stocks.Stock has been
    immediately deprecated

Bug Fixes

  • Certain failed requests which erroneously-returened
    IEXAuthorizationError now return IEXQueryError
