Core team fixed a whole bunch of splinters with sharding deployment: memory issue, garbage collection issue, bug in shard_tries:, panic if node tries to sync just after sharding upgrade;
Infrastructure team did lots of resizing of instances following larger storage demand. They also helped Feiyu and Aurora projects with their nodes;
Infrastructure team did a lot of work on releasing patches, implementing RPC throttling, and other kinds of preparations for the upcoming project launches.
