Solana Tech Roundup
This week the Solana StackExchange went live in private beta. If you have any questions or want to help out by answering, please go support the Solana StackExchange! Even though it is in private beta, all you need is to create an account to use it.
Feature Highlight
Extending Program Data Accounts
The extension of program data accounts allows anyone to allocate more data for a specific program. Going hand-in-hand with the recent realloc feature where you can have dynamic account sizes, you will be able to dynamically resize programs as well.
No longer will you have to pay double for your programs to give yourself some buffer room. You will be able to pay exactly what you expect to allocate when you deploy a program.
Commit Highlights
Extending Program sizes! As discussed in the feature highlight, this is a great upcoming feature
Sender stake doesn't matter with transaction prioritization with this change. The only thing that matters is the compute-price on the transaction
You can now get data returned from transactions during simulateTransaction
Interested in trying out the Transactions v2 spec? You can now use web3.js to interact with the address lookup tables on Devnet or Testnet.
