 ### Requirements
 
-- For Rust components and wRPC applications: `rust` >= 1.78
-
-  `wasm32-wasip1` target will be used in examples, because it is currently available in stable Rust and also conveniently configured in [`rust-toolchain.toml`](./rust-toolchain.toml) in the root of this repository. `wrpc-wasmtime` will automatically componentize a Wasm module on instantiation.
-
-  [`wasm32-wasip2`](https://doc.rust-lang.org/nightly/rustc/platform-support/wasm32-wasip2.html) can be used instead, if desired.
+- For Rust components and wRPC applications: `rust` >= 1.82
 
 - For [NATS.io] transport: `nats-server` >= 2.10.20 or [`docker`](https://www.docker.com/) >= 24.0.6 (or any other OCI runtime)
