Solana's developer experience just got a major overhaul with a critical upgrade rolling out today—one of the most significant devex improvements in the network's history. This isn't just incremental tweaking; it's something that's been a pain point for builders for the past three years. The upgrade tackles fundamental friction in the development workflow, making it easier for developers to build, test, and deploy on Solana. A move like this could reshape how developers interact with the ecosystem and lower barriers to entry for new projects.
