leptos 0.2.4

`v0.2.4`

on Rust Cargo

v0.2.3 fixed support for stable Rust, which I temporarily broke in v0.2.2.

The main change in v0.2.4 is a rewritten reactive system. This didn't involve any breaking API changes, except to the extent that fixing bugs and glitchy behavior breaks apps that depend on the glitches. It pretty significantly improves the performance of the reactive system on deep graphs (i.e., when you have a chain of dependencies like memos leading from a signal to an effect), as well as fixing reactive "glitching" behaviors in ways that make effects run more efficiently. You can read more about the details here.

Other changes:

• improved error handling in <ActionForm/>
• Support for using signals directly in the view in stable Rust
• cancelable versions of set_timeout, request_idle_callback, and request_animation_frame (all ending with with_handle)
• a debounce helper that makes it easy to debounce event listeners
• allow manual disposal of signals before the current reactive cope is disposed with the SignalDispose trait (and .dispose()) function, to avoid leaking memory if you create a list of signals at the root scope
• allow batching multiple updates with Scope::batch() before running effects
• many small bugfixes
