New API Features & Dashboard Updates, Quantopian-Closing

We recently launched multiple API features and dashboard updates to support our users. We added a new parameter to the Liquidation API that allows users to cancel open orders when liquidating positions, as well as a filter by symbols in the Orders API. To help with the transition of Quantopian's closure, we've made Zipline-Trader compatible with multiple brokerages, including Alpaca and IBKR, providing an alternative for algorithmic trading on open source tools without relying on online services. Our dashboard now includes more information about positions and balances under the "Account" section, making it easier to manage user accounts.
