Assets stats are disabled by default. This can be changed using an environment variable (ENABLE_ASSET_STATS=true) or CLI parameter (--enable-asset-stats=true). Please note that it has a negative impact on a DB and ingestion time.
In "Offers for Account", last_modified_time field endpoint can be null when ledger data is not available (has not been ingested yet).
"Trades for Offer" endpoint will query for trades that match the given offer on either side of trades, rather than just the "sell" offer. Offer IDs are now synthetic.
New /operation_fee_stats endpoint includes fee stats for the last 5 ledgers.
"Trades" endpoint can now be streamed.
In "Trade Aggregations" endpoint, offset parameter has been added.
Account flags now display auth_immutable value.
Rate limiting in streams has been changed to be more fair. Now 1 credit has to be paid every time there's a new ledger instead of per request.
