This past week the Solana network hit 100 billion transactions over the total time being live. Address lookup tables and versioned transactions are still slated to be activated near the end of September. If you're interested on learning more about address lookup tables and versioned transactions, check out the thread by solana devs on twitter.
As a reminder, if you're a developer going to Breakpoint November 4-7, make sure you apply for a discounted developer ticket.
The extend program data feature is a result of the recent realloc change that happened with accounts earlier this year. With reallocing accounts now being possible, it makes sense to be able to do this with programs as well.
Currently developers pay for twice the program size to be stored on chain at first deployment and may never need all that space. Once the extend program data feature is activated, a developer can pay as they grow their program instead.
The account compression program now has a JS library to interact with it.
