Change Highlight

Transaction Prioritization

There's so much discussion on the upcoming transaction prioritization changes that it can be easy to get lost on what is happening.

You can pay for transaction prioritization today.

Using the requestUnits ComputeBudget Program instruction and increasing the amount additionalFee paid, you will be prioritized over other transactions with less fees paid in mainnet-beta today.

This instruction is deprecated in later releases in favor of setComputePrice, so be on the lookout for when you need to update your code. Transaction prioritization will be based on transaction fees is based on the highest fees per compute paid.

Commit Highlight

The compute budget and fee docs were updated to reflect the current state of development. Be sure to check them out!
