unicorn-binance-websocket-api Change Log

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

1.28.0.dev (development stage/unreleased/unstable)

1.28.0

Changed

  • the stream signal DISCONNECT includes last_received_data_record which returns now None if there is no record available

Fixed

Removed

  • Deprecated methods set_private_api_config() and get_websocket_uri_length()

1.27.0

Added

Changed

  • max subscriptions of futures endpoints to 200 issue#127
  • max subscriptions of jex endpoint to 10

Fixed

  • Added a gracefull shutdown if the Python interpreter dies issue#131

1.26.0

Added

Changed

  • log warning about high cpu usage is logged after 5 seconds if > 95%

1.25.0

Added

Changed

  • get_stream_subscriptions() returns now the used request_id instead of True

1.24.0

Added

Removed

  • unused import of ujson in connection class
  • 4 parameters from _create_stream_thread

1.23.0

Added

  • timestamp to receiving_speed_peak in manager
  • log warning if the cpu usage is > 95%
  • logging.info if new highest_receiving_speed is reached

Fixed

  • listen_key was printed to logfiles
  • listen_key cache time was not set in get_listen_key() so it pinged immediately after its creation again, which caused a higher weight
  • restart stream if "The future belongs to a different loop than the one specified as the loop argument" issue#121

Changed

  • renamed _add_socket_to_socket_list to _add_stream_to_stream_list

1.22.0

Added

  • get_current_receiving_speed_global()
  • better logging in socket class
  • highest_receiving_speed in print_summary()

Changed

  • renamed variable ubwa to manager in restclient class
  • renamed variable unicorn_binance_websocket_api_manager to manager in socket class
  • renamed variable total_receiving_speed to average_receiving_speed
  • renamed variable unicorn_binance_websocket_api_connection to connection
  • renamed variable unicorn_binance_websocket_api_socket to socket

Added

  • is_update_availabe_unicorn_fy() and get_version_unicorn_fy()
  • new_output to replace_stream()

Changed

  • Rewrite of BinanceWebSocketApiRestclient(), its more or less stateless but compatible to the current system. Now we use one instance globally instead of creating a new one every time we need it. It will help to implement isolated margin with more than one symbol. issue#111
  • time.sleep() in _frequent_checks() from 0.1 to 0.3 seconds

Fixed
