leptos-rs/leptos v0.4.5 on GitHub

I've gotten back into a regular rhythm of patch releases pulling in some of the smaller bugfixes, but haven't had time to write release notes for each one. I should just auto-generate them, I suppose—sorry about that!

Anyway here's a quick summary of the new features included in the past few releases. The full changelog below includes various bugfixes, chores, and updates to the docs as well.

Some useful fixes to support for cargo leptos watch --hot-reload
leptos_axum::extract_with_state to support extractors that use a State, if it's been provided via context in a custom handler
The watch function, which functions as a more configurable create_effect, including the ability to explicitly list dependencies, stop listening to them, whether to run immediately or lazily, etc.
Better 404 page support in Actix examples and templates
Added support for adding Content-Security-Policy nonces to inline script and style tags with use_nonce and the nonce feature
Rewritten <For/> diffing algorithm that both fixes a number of correctness issues/edge cases in <For/> and drops ~10kb from the WASM binary

Basically, a bunch of small but really useful changes, and about a hundred bugfixes.

I also just want to give a shout-out to @agilarity, who's become one of the top contributors to the library through a very helpful focus on CI and testing. If you're ever looking for a great model of how to test a Leptos frontend app, the counters_stable example now features two complete test suites, one in JS using Playwright and one written in Rust using wasm_bindgen_test. This has been a huge amount of very impressive work.
