### Important updates:
* Add support for Batch precompile : ([#1498](https://github.com/PureStake/moonbeam/pull/1498))
Smart contract developers will be able to natively execute multiple contract calls in batch using our freshly deployed precompile. 
This addition provides a secure way to atomically perform multiple transfers in a single transaction or allows a better management of transaction fees. 

* Add vrf key to session keys type ([#1480](https://github.com/PureStake/moonbeam/pull/1480))  
We are adding a new key for collators in this runtime for the upcoming VRF functionality.
 
* Reworks `delegator_leave` to now use the Revoke logic : ([#1515](https://github.com/PureStake/moonbeam/pull/1515))
A delegator scheduling a `delegator_leave` will schedule a batch revoke on all delegations.
