Anza has published a migration guide for SBPFv3, the bytecode format that becomes the only deployable one on Solana once SIMD-0500 activates in Agave v4.4. Deployed programs keep running, but 17,332 upgradeable programs still on old bytecode will need a rebuild before they can ship another upgrade.
Four Pillars' 131-page x402 report models annual agent payment volume reaching as high as $1.9T by 2028, with roughly 96% of it landing in purchases an agent makes without a human approving anything.

Dev3pack is running its global hackathon October 30 to November 1, 2026, a three-day hybrid event with more than 40 in-person build stations across four continents.
