-If you’re on `stable`, note the following:
+The `nightly` feature enables the function call syntax for accessing and setting signals, as opposed to `.get()` and `.set()`.

This is only possible with nightly Rust and the `nightly` feature.

+Also note that in some cases, the cfg feature `has_std` will not be set, which may cause build errors with some dependencies which check for `has_std`. You may fix any build errors due to this by adding:
+```toml
+[build]
+rustflags = ["--cfg=has_std"]
+```
+
 And you'll need to add `panic = "abort"` to `[profile.release]` in `Cargo.toml`. Note that this applies the same `build-std` and panic settings to your server binary, which may not be desirable. Some further exploration is probably needed here.
 
 5. One of the sources of binary size in WASM binaries can be `serde` serialization/deserialization code. Leptos uses `serde` by default to serialize and deserialize resources created with `create_resource`. You might try experimenting with the `miniserde` and `serde-lite` features, which allow you to use those crates for serialization and deserialization instead; each only implements a subset of `serde`’s functionality, but typically optimizes for size over speed.

 **But remember**: Leptos will handle all the details of this encoding and decoding for you. When you use a server function, it looks just like calling any other asynchronous function!
 
+> **Why not `PUT` or `DELETE`? Why URL/form encoding, and not JSON?**
+>
+> These are reasonable questions. Much of the web is built on REST API patterns that encourage the use of semantic HTTP methods like `DELETE` to delete an item from a database, and many devs are accustomed to sending data to APIs in the JSON format.
+> 
+> The reason we use `POST` or `GET` with URL-encoded data by default is the `<form>` support. For better or for worse, HTML forms don’t support `PUT` or `DELETE`, and they don’t support sending JSON. This means that if you use anything but a `GET` or `POST` request with URL-encoded data, it can only work once WASM has loaded. As we’ll see [in a later chapter](../progressive_enhancement), this isn’t always a great idea.
+> 
+> The CBOR encoding is suported for historical reasons; an earlier version of server functions used a URL encoding that didn’t support nested objects like structs or vectors as server function arguments, which CBOR did. But note that the CBOR forms encounter the same issue as `PUT`, `DELETE`, or JSON: they do not degrade gracefully if the WASM version of your app is not available.

 ## An Important Note on Security
 
 Server functions are a cool technology, but it’s very important to remember. **Server functions are not magic; they’re syntax sugar for defining a public API.** The _body_ of a server function is never made public; it’s just part of your server binary. But the server function is a publicly accessible API endpoint, and it’s return value is just a JSON or similar blob. You should _never_ return something sensitive from a server function.
