🔓 Announcing the Open Sourcing of Linera's Developer Manual! 🔓
Just as microchains further decentralize blockchain infrastructure, we believe documentation should be in the hands of the users as well: bit.ly/git-documentation

What's in the dev manual? The Linera Developer Manual at www.linera.dev hosts comprehensive guides on:
⚙️ Linera's Rust SDK
⛓️ The Linera Protocol, Microchains, Wallets, and Node Services
🫧 Writing, Deploying, and Testing Linera Applications
🌐 Persistent Storage, Validators, and Block Creation

Why does this matter? By open-sourcing our documentation, we're inviting developers worldwide to contribute, propose fixes, and update our developer manual directly. This fosters a collaborative environment core to Web3 where transparency and innovation go hand-in-hand.

How does one contribute? Check out our mdBook repository at bit.ly/git-documentation. Whether it's through submitting pull requests or adding issues, your input is invaluable as we chart a revolutionary path in blockchain design.

Stay connected: As always, this is just the beginning. We'll continue to update and expand the manual to cover more topics, include additional walkthroughs, and provide even more value to our growing developer community.

Let's build the future of Web3 applications—together. 🤝
🚀 Announcing the Linera SDK v0.10 for Rust
This latest release includes important changes with the goal of making Linera applications simpler to write.
https://bit.ly/linera-sdk-v0-10

🔧 Improved framework to define WASM application states: We separated execution states from the storage state. Now, applications directly define types for 'Contract' and 'Service' execution traits, improving the definition of non-persistent runtime state.

👋 Sunsetted *Context arguments: We've replaced these with a runtime object for a cleaner and more efficient handling of callbacks in the 'Contract' and 'Service' traits.

🏁 Enhanced Smart Contract execution: With a defined lifetime for contract execution states via the new 'finalize' method, applications are now more efficient and capable of tracking transaction activities more effectively.

This new 'finalize' method, along with removing the experimental 'sessions,' has streamlined contract functionality, making it easier to implement features like flash loans without the need for undocumented concepts.

🔀 Simplified contract interface: We've merged operations and application calls into a single, clearer concept. This change makes code writing simpler and clarifies the purpose of public and private entry-points.

🧪 Ready to test your apps on the new SDK? The latest Linera Devnet (2024-03-26) instance is here for you to explore all these features in action. Try it out and see how v0.10 of the SDK can enhance your Linera application: https://bit.ly/linera-devnet-2024_03_26

💡 Have questions or feedback? Drop us a reply in the repo, community Telegram chat (t.me/linera_official), or on the forum. We love hearing from our growing developer community and are here to help!

🚀 Announcing the Linera SDK v0.11 for Rust
The SDK has been simplified and extended in many ways to make it easier to build a wide variety of applications.
https://forum.linera.io/t/releasing-linera-sdk-v0-11/221

🔧Wasm bindgen and VM upgrade
We rolled out a new generic framework to generate API stubs for Wasm containers, called “Witty”. This means that Wasm-compatible source languages supported by wit-bindgen will be easier to support in the future. This change also allowed us to upgrade to Wasmer v4.

👋 API Simplifications
We improved naming and made applications control their persistent state more explicitly. This allowed us to remove the custom test runner for Wasm. We also stopped using "Result" to manage errors in contract APIs.

🏁 New features
Application services can now access the Internet, as showcased by the new LLM Stories example. We also added an experimental support for HTTP queries in contracts, using a new oracle mechanism. Initial support for Ethereum interoperability was added, which will make use of this feature.

🔧New examples
We added instructions to use the AMM application for atomic swaps between two users using a shared chain. We also added an AI demo where the service part of an application can run an LLM model to generate short stories.

🔀 Core Protocol
We made a configurable policy for accepting/rejecting incoming messages. We added the commands linera wallet forget-keys and forget-chain. We made progress in the support of fallback leaders and public chains.

🧪 Ready to test your apps on the new SDK? Instructions to deploy applications on the new corresponding Devnet instance (devnet-2024-05-07) can be found on https://linera.dev
