+We have a fairly extensive CI setup that runs both lints (like `rustfmt` and `clippy`)
 and tests on PRs. You can run most of these locally if you have `cargo-make` installed.
 
+Note that some of the `rustfmt` settings used require usage of the nightly compiler.
+Formatting the code using the stable toolchain may result in a wrong code format and
+subsequently CI errors.
+Run `cargo +nightly fmt` if you want to keep the stable toolchain active.
+You may want to let your IDE automatically use the `+nightly` parameter when a
+"format on save" action is used.
+
 If you added an example, make sure to add it to the list in `examples/Makefile.toml`.

-The new rendering approach being developed for 0.7 supports “universal rendering,” i.e., it can use any rendering library that supports a small set of 6-8 functions. (This is intended as a layer over typical retained-mode, OOP-style GUI toolkits like the DOM, GTK, etc.) That future rendering work will allow creating native UI in a way that is much more similar to the declarative approach used by the web framework.
+The 0.7 update originally set out to create a "generic rendering" approach that would allow us to reuse most of the same view logic to do all of the above. Unfortunately, this has had to be shelved for now due to difficulties encountered by the Rust compiler when building larger-scale applications with the number of generics spread throughout the codebase that this required. It's an approach I'm looking forward to exploring again in the future; feel free to reach out if you're interested in this kind of work.

+Yew is the most-used library for Rust web UI development, but there are several differences between Yew and Leptos, in philosophy, approach, and performance.
 
 - **VDOM vs. fine-grained:** Yew is built on the virtual DOM (VDOM) model: state changes cause components to re-render, generating a new virtual DOM tree. Yew diffs this against the previous VDOM, and applies those patches to the actual DOM. Component functions rerun whenever state changes. Leptos takes an entirely different approach. Components run once, creating (and returning) actual DOM nodes and setting up a reactive system to update those DOM nodes.
 - **Performance:** This has huge performance implications: Leptos is simply much faster at both creating and updating the UI than Yew is.
 - **Server integration:** Yew was created in an era in which browser-rendered single-page apps (SPAs) were the dominant paradigm. While Leptos supports client-side rendering, it also focuses on integrating with the server side of your application via server functions and multiple modes of serving HTML, including out-of-order streaming.
 
-- ### How is this different from Dioxus?
+### How is this different from Dioxus?
 
 Like Leptos, Dioxus is a framework for building UIs using web technologies. However, there are significant differences in approach and features.
 
 - **VDOM vs. fine-grained:** While Dioxus has a performant virtual DOM (VDOM), it still uses coarse-grained/component-scoped reactivity: changing a stateful value reruns the component function and diffs the old UI against the new one. Leptos components use a different mental model, creating (and returning) actual DOM nodes and setting up a reactive system to update those DOM nodes.
 - **Web vs. desktop priorities:** Dioxus uses Leptos server functions in its fullstack mode, but does not have the same `<Suspense>`-based support for things like streaming HTML rendering, or share the same focus on holistic web performance. Leptos tends to prioritize holistic web performance (streaming HTML rendering, smaller WASM binary sizes, etc.), whereas Dioxus has an unparalleled experience when building desktop apps, because your application logic runs as a native Rust binary.
 
-- ### How is this different from Sycamore?
+### How is this different from Sycamore?
 
 Sycamore and Leptos are both heavily influenced by SolidJS. At this point, Leptos has a larger community and ecosystem and is more actively developed. Other differences:
 
 - **Templating DSLs:** Sycamore uses a custom templating language for its views, while Leptos uses a JSX-like template format.
 - **`'static` signals:** One of Leptos’s main innovations was the creation of `Copy + 'static` signals, which have excellent ergonomics. Sycamore is in the process of adopting the same pattern, but this is not yet released.
-- **Perseus vs. server functions:** The Perseus metaframework provides an opinionated way to build Sycamore apps that include server functionality. Leptos instead provides primitives like server functions in the core of the framework.
