<details>

<summary>Version v1.2 (11/15/2022)</summary>

Added two new streams: price and swaps. Contains breaking changes to transaction submission mechanisms, which enables submitting batches of transactions. Transactions will also now be propagated to all nodes in the BDN for redundancy.

This version contains experimental support for Jupiter in the `Quotes` endpoint and `Prices` stream endpoint. Note that the endpoints in Trader API are powered by Geyser, which is faster but will also result in subtly different state representations than what you'd normally get over Solana RPC. We welcome any feedback you have on these results.

**New endpoints:**

**API Streams**

* Prices
* Swaps
