Summary

This release introduces support for optional keys in the KeyValue pipe and standardizes signal input access in Angular Elements to match decorator input behavior. It also includes several bug fixes for animations, template literal compilation, and migration scripts.

⚠️ Breaking Changes

Signal inputs in custom elements (Angular Elements) are now accessed via direct property access instead of function calls. To fix, remove the parentheses when accessing signal inputs on element references (e.g., change 'elementRef.newInput()' to 'elementRef.newInput').

Migration Steps

Update code accessing Angular Elements signal inputs to use property access instead of calling them as functions.
