We are happy to announce the release of CCXT version 4!

During the last months we have been working hard on a few major improvements to the library adding important upgrades, including:

• the merge of CCXT Pro Websocket APIs with the master repository of CCXT
• the ESM and TypeScript migration for type-safety and portability
• AST-based transpilation to support popular programming languages like C#
• unification of perpetual swaps and futures markets among the leading exchanges like Binance and BitMEX
• adding Bybit v3 and v5 APIs support
• cryptocom v1 upgrades
• per-exchange class method specifications: https://docs.ccxt.com/#/spec
• unified proxy support
• and many many more fixes and unifications

We highly recommend downloading and installing the most recent release of CCXT version 4.0.3+ in order to get a much smoother experience for your trading operations.
