+### Setting defaults via CSS
+
+You can use certain CSS custom properties to set icon defaults, not just on the icon itself, but any ancestor.
+This can be useful when you want certain parameters to vary based on context, e.g. icons inside callouts or all icons for a given theme.
+
+:::warning
+These CSS properties are intended to set **defaults**, and thus only make a difference when the corresponding attributes are not set.
+In future versions of Web Awesome, we may change this behavior to allow CSS properties to override attributes if `!important` is used.
+:::
+
+For example, here is how you can use CSS custom properties to set a default icon for each type of callout:
+
+```html {.example}
+<wa-callout>
+  <!-- Look ma, no attributes! -->
+  <wa-icon slot="icon"></wa-icon>
+  This is a normal callout.
+</wa-callout>
+
+<wa-callout variant="danger">
+  <wa-icon slot="icon" name="dumpster-fire" variant="solid"></wa-icon>
+  This is a callout with an explicit icon, which overrides these defaults.
+</wa-callout>
+
+<wa-callout variant="warning">
+  <!-- Look ma, no attributes! -->
+  <wa-icon slot="icon"></wa-icon>
+  Here be dragons.
+</wa-callout>
+
+<wa-callout variant="danger">
+  <!-- Look ma, no attributes! -->
+  <wa-icon slot="icon"></wa-icon>
+  Here be more dragons.
+</wa-callout>
+
+<wa-callout variant="success">
+  <!-- Look ma, no attributes! -->
+  <wa-icon slot="icon"></wa-icon>
+  Success!
+</wa-callout>
+
+<style>
+wa-callout {
+  --wa-icon-variant: regular;
+  --wa-icon-name: info-circle;
+
+  &[variant="warning"] {
+    --wa-icon-name: triangle-exclamation;
+  }
+
+  &[variant="danger"] {
+    --wa-icon-name: circle-exclamation;
+  }
+
+  &[variant="success"] {
+    --wa-icon-name: circle-check;
+  }
+}
+</style>
+```
+
+You can even set icons dynamically, as a response to user interaction or media queries.
+For example, here's how we can change the icon on hover:
+
+```html {.example}
+<wa-button class="github" href="https://github.com/webawesome/webawesome"><wa-icon slot="prefix" fixed-width></wa-icon> GitHub Repo</wa-button>
+<style>
+.github {
+  --wa-icon-name: github;
+  --wa-icon-family: brands;
+
+  &:hover {
+    --wa-icon-name: arrow-up-right-from-square;
+    --wa-icon-family: classic;
+  }
+}
+</style>
+```
+
 ### Colors
 
 Icons inherit their color from the current text color. Thus, you can set the `color` property on the `<wa-icon>` element or an ancestor to change the color.

-- Added the `wa-cloak` utility to prevent FOUCE
-- Added the `allDefined()` utility for awaiting component registration
-- Fixed `wa-pill` class for text fields
-- Fixed `pill` style for `<wa-input>` elements
-- Fixed a bug in `<wa-color-picker>` that prevented light dismiss from working when clicking immediately above the color picker dropdown
+### Enhancements
+
+- Added `appearance` to [`<wa-details>`](/docs/components/details) and [`<wa-card>`](/docs/components/card) and support for the [appearance utilities](/docs/utilities/appearance/) in the [`<details>` native styles](/docs/native/details).
+- Added an `orange` scale to all color palettes
+- Added the [`.wa-cloak` utility](/docs/utilities/fouce) to prevent FOUCE
+- Added the [`allDefined()` utility](/docs/usage/#all-defined) for awaiting component registration
+
+### Bug fixes
+
+- Specifying inherited CSS properties on `<wa-tooltip>` now works as expected ([thanks Dennis!](https://github.com/shoelace-style/webawesome-alpha/discussions/203))
+- Fixed a bug in `<wa-select>` that made it hard to use with VueJS, Svelte, and many other frameworks
 - Fixed a bug in `<wa-select multiple>` that sometimes resulted in empty `<div>` elements being output
+- Fixed a bug where changing a `<wa-option>` label wouldn't update the display label in `<wa-select>`
+- Added default spacing to icons slotted into `<wa-tab>`
+- Lots of fixes around pill-shaped elements:
+  - Fixed the `wa-pill` class for text fields
+  - Fixed `pill` style for `<wa-input>` and `<wa-radio-button>` elements
+- Fixed a bug in `<wa-radio-button>` that prevented active buttons from receiving the correct styles
+- Fixed a bug in `<wa-button>` that prevented the focus ring from showing in Safari
+- Fixed alignment of `<wa-dropdown>` inside button groups
+- Removed close watcher logic to backdrop hide animation bugs in `<wa-dialog>` and `<wa-drawer>`; this logic is already handled and we'll revisit `CloseWatcher` when browser support is better and behaviors are consistent
+- Revert `<wa-dialog>` structure and CSS to fix clipped content in dialogs (WA-A #123) and light dismiss in iOS Safari (WA-A #201)
+- Fixed a bug in `<wa-color-picker>` that prevented light dismiss from working when clicking immediately above the color picker dropdown
+- Fixed a bug in `<wa-progress>` that prevented Safari from animation progress changes
+- Fixed the missing indeterminate icon in [native checkbox styles](/docs/native/checkbox)
+- Fixed a bug in `<wa-radio>` where elements would stack instead of display inline
+- Docs fixes:
+  - Fixed the search dialog's styles so it doesn't jump around as you search
+  - Theme cards now have icons

 ```ts
@@ -32,6 +36,33 @@ await allDefined();
 // All Web Awesome components on the page are ready!
 ```
 
+#### Advanced Usage
+
+By default, `allDefined()` will wait for all `wa-` prefixed custom elements within the current `document` to be registered.
+You can customize this behavior by passing in options:
+- `root` allows you to pass in a different element to search within, or a different document entirely (defaults to `document`).
+- `match` allows you to specify a custom function to determine which elements to wait for. This function should return `true` for elements you want to wait for and `false` for those you don't.
+- `additionalElements` allows you to wait for custom elements to be defined that may not be present in the DOM at the time `allDefined()` is called. This can be useful for elements that are loaded dynamically via JS.
+
+Here is an example of using `match` and `root` to await registration of Web Awesome components inside an element with an id of `sidebar`, plus a `<my-component>` element if present in the DOM, and `<wa-slider>` and `<other-slider>` elements whether present in the DOM or not:
+
+```js
+import { allDefined } from '/dist/webawesome.js';
+
+await allDefined({
+  match: tagName => tagName.startsWith('wa-') || tagName === 'my-component',
+  root: document.getElementById('sidebar'),
+  additionalElements: ['wa-slider', 'other-slider']
+});
+```
+
+:::warning
+`additionalElements` will only wait for elements to be registered — it will not load them.
+If you're using the autoloader plus custom JS to inject HTML dynamically, **you need to make sure your JS runs _before_ the `await allDefined()` call**,
+otherwise you could run into a chicken and egg issue:
+since the autoloader will not load elements until they are present in the DOM, the promise will never resolve and your JS to inject them will not run.
+:::

-## Waiting for Components to Load
-
-Web components are registered with JavaScript, so depending on how and when you load Web Awesome, you may notice a [Flash of Undefined Custom Elements (FOUCE)](https://www.abeautifulsite.net/posts/flash-of-undefined-custom-elements/) when the page loads. There are a couple ways to prevent this, both of which are described in the linked article.
-
-One option is to use the [`:defined`](https://developer.mozilla.org/en-US/docs/Web/CSS/:defined) CSS pseudo-class to "hide" custom elements that haven't been registered yet. You can scope it to specific tags or you can hide all undefined custom elements as shown below.
-
-```css
-:not(:defined) {
-  visibility: hidden;
-}
-```
-
-As soon as a custom element is registered, it will immediately appear with all of its styles, effectively eliminating FOUCE. Note the use of `visibility: hidden` instead of `display: none` to reduce shifting as elements are registered. The drawback to this approach is that custom elements can potentially appear one by one instead of all at the same time.
-
-Another option is to use [`customElements.whenDefined()`](https://developer.mozilla.org/en-US/docs/Web/API/CustomElementRegistry/whenDefined), which returns a promise that resolves when the specified element gets registered. You'll probably want to use it with [`Promise.allSettled()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/allSettled) in case an element fails to load for some reason.
-
-A clever way to use this method is to hide the `<body>` with `opacity: 0` and add a class that fades it in as soon as all your custom elements are defined.
-
-```html
-<style>
-  body {
-    opacity: 0;
-  }
-
-  body.ready {
-    opacity: 1;
-    transition: 0.25s opacity;
-  }
-</style>
-
-<script type="module">
-  await Promise.allSettled([
-    customElements.whenDefined('wa-button'),
-    customElements.whenDefined('wa-card'),
-    customElements.whenDefined('wa-rating')
-  ]);
-
-  // Button, card, and rating are registered now! Add
-  // the `ready` class so the UI fades in.
-  document.body.classList.add('ready');
-</script>
-```
-
 ## Component Rendering and Updating
 
 Web Awesome components are built with [Lit](https://lit.dev/), a tiny library that makes authoring custom elements easier, more maintainable, and a lot of fun! As a Web Awesome user, here is some helpful information about rendering and updating you should probably be aware of.
