We have shipped various of improvements to the Stencil project and
runtime. You can take a close look at our
[changelog](https://github.com/ionic-team/stencil/blob/main/CHANGELOG.md)
but since `v4.20.0` we mainly shipped improvements on the following
issues:
## Major Improvements:
- Enhanced Shadow DOM and hydration support
- Improved client-side hydration for SSR
- Better handling of shadow root styles and component hydration
- More reliable serialization of Shadow DOM components
## Key Bug Fixes:
- Resolved performance issues due to detached nodes in memory
- Fixed several critical issues with scoped slots and component styling
- Improved handling of SVG class attributes and template tags
- Enhanced runtime decorator functionality
- Better handling of form-associated callbacks
## Technical Updates:
- Updated to TypeScript 5.5
- Added support for customizable Mermaid diagram colors in documentation
I don't see any critical changes that may impact Ionic users and feel
confident we can ship this.

Currently the standalone test app for router-link in Angular imports all
of `RouterModule` when it only needs to import `RouterLink` from
`@angular/router`
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
Now, the Angular test app will import only what it needs from router
instead of over-importing.

`@stencil/vue-output-target@v0.9.0`:

`@stencil/vue-output-target/runtime` similar to what we did in React
- this version requires some updates to Vue and TypeScript as well
- adjustments related to that update

`ion-segment-content` instances

the value of the first `ion-segment-content`
