Email form Bitfinex:
Bitfinex is growing faster than ever, and we are pleased that our platform, trading engine, and APIs have remained reliable and performant during these exciting days.
However, in order to continue to be able to accommodate current demand and future scaling, the Bitfinex REST and WebSocket APIs will be upgraded on Thursday, August 31st.
You are receiving this email because it appears you might be a Bitfinex API user and we wish to alert our API users about these changes in particular, as the changes may affect automated trading applications using the APIs.
In order to continue to be able to handle spikes in platform load, we need to make adjustments to how we return historical snapshot messages when authenticating to the WebSocket APIs. Currently, the snapshots hos, hts, hfts, hfos, hfls, and hfcs are returned in the WebSocket feed after authenticating. As of August 31st, these snapshots will no longer be returned via the WebSocket feed (both V1 and V2) after August 31 and equivalent REST endpoints are available as replacements. All update messages will remain unchanged.
If your API application relies on these historical snapshots, these changes may affect your application. Please take the time to review the following and make sure to properly update your code if needed.
