📌 Problem
After updating to the latest version of one or more of the following tools, my Anchor program fails to compile or behave as expected:
anchor version: 0.29.0
rustc version: 1.75.0
solana CLI version: 1.17.18
This appears to be caused by a mismatch between the required versions that Anchor expects and what is currently installed in my local environment.
🧪 Observed Behavior
Compilation errors related to Solana crates or unstable Rust features.
Runtime issues or failed deployments when using anchor deploy.
✅ Expected Behavior
A clear compatibility matrix and smoother developer experience across matching toolchain versions.
🔍 Steps to Reproduce
Install the tool versions mentioned above.
Create a new Anchor project using anchor init.
Attempt to build or deploy the project.
📎 Additional Context
I am working in a WSL/Unix environment.
The project uses Anchor version 0.29.0, and compilation errors are triggered specifically by mismatched Solana SDK crate versions or unsupported Rust syntax.
💡 Suggestions
A compatibility table in the Anchor documentation for anchor, rustc, and solana versions would be very helpful.
Clear error messages when version mismatches occur.
