This week there was a lot of work stabilizing 1.9 for release and getting QUIC ready for 1.10. If you're interested in testing 1.9, it is currently deployed to Devnet. Deployment to mainnet-beta is expected as early as next week!
As a part of the 1.9 release, some major changes are being made to compute budget on transactions.
Along with this change, you can now request more compute for your transaction at a small fee.
Note: To request more compute for a transaction, the first instruction must be the compute budget request instruction.
You can find examples of how to request more compute on the Solana Cookbook.
As part of implementing the Comprehensive Compute Fees in 1.9, it was found that there was a bug in the implementation where transactions could have very high fees. These changes will likely be implemented at a later date. If you're interested in contributing, check out the detailed analysis of the issue.
