we just shipped a new update that will help your transactions hit even faster 

you can now fully customize & control different variables like bribes & priority fees 

what does that mean though?

bribe: 
a bribe is a payment made to jito to prioritize a transaction over another 
the higher the bribe, the faster your transaction is validated 

priority fee: 
priority fees on solana allow you to attach a higher fee which also incentivizes validators to process them quickly. By setting these higher, your transaction gains priority over those with lower fees to get faster confirmation times.
