📜 Solana Scribes Winners

Solana Scribes, the first ever written content contest for Solana, showcased a wide range of submissions across 54 tracks, each aimed to advance the entire Solana ecosystem.

After a thorough judging period the winners have been announced!

I can't cover all the winners here, but I'm featuring the winners of the Development on Solana track where participants were asked to "write a research article on the state of development on Solana".

Huge congrats to each of the winners and a big thanks to everyone that took the time to create useful content about Solana!

⚓ Anchor 0.30.0

Version 0.30.0 release of Anchor introduces several big updates for developers using Anchor.

These updates aim to streamline the development process, reduce errors, and provide more powerful tools for Solana blockchain development.

These changes and updates include:

IDL Type Specification: The IDL type specification and generation have been rewritten. There's now a requirement to include idl-build in your Cargo.toml for IDL generation to work.

Program Declaration: Dependency-free program declaration is now possible with the declare_program! macro, which simplifies creating program clients without dependency issues.

Token Extensions: New account constraints for Token Extensions are introduced, enhancing the security and functionality of token operations.

CPI Wrappers and Interface Attribute: The release includes CPI wrappers for Token Extensions and a new #[interface] attribute for specifying custom instruction discriminators.

Less Heap Allocations: The Borsh serialization now allocates less memory by default, reducing from 1024 bytes to 256 bytes, and includes a new method for writing instruction data.

CLI Enhancements: Updates include support for priority fees, simplified IDL commands, verifiable deployments, and the ability to deactivate test-validator features.

Rust and TypeScript Updates: Significant changes in type handling and program interaction methods in TypeScript, improved account resolution, and a shift towards more explicit type-safe coding practices.

Developers should also upgrade to Solana CLI v1.18.8 and update your project's Anchor crates and TS packages to version 0.30.0.

👩‍🔧 Solana Updates

Solana v1.17.31 was released in response to ongoing network congestion issues.

This update includes several enhancements specifically designed to improve the handling of increased network activity and demand:

It's important to remember that this update is a partial fix to address congestion issues, but does not represent the more comprehensive updates expected in v1.18.
