-## Eth/65 not backwards compatible 
+## Scope of logs query causing Besu to hang
+
+[`eth_getLogs` queries that are too large or too broad can cause Besu to never return](https://github.com/hyperledger/besu/issues/944).

+Workaround - Limit the number of blocks queried by each `eth_getLogs` call.

+## Eth/65 loses peers 
 
 From v1.4.4, `eth/65` is [disabled by default](https://github.com/hyperledger/besu/pull/741). 
 
-The `eth/65` change is not [backwards compatible](https://github.com/hyperledger/besu/issues/723). 
-This has the following impact: 
-* In a private network, nodes using the 1.4.3 client cannot interact with nodes using 1.4.2 or earlier
-clients. 
-* On mainnet, synchronizing eventually stalls.
+If enabled, peers will slowly drop off and eventually Besu will fall out of sync or stop syncing.
 
 A fix for this issue is being actively worked on.
