Breaking Changes

●Issue #1

The 'ThisReceiver' class no longer inherits from 'ImplicitReceiver' in the compiler AST. Code relying on this inheritance hierarchy for type checking or property access may need to be updated.

Migration Steps

  1. 1
    Check custom compiler plugins or AST transformations for reliance on ThisReceiver inheriting from ImplicitReceiver.
  2. 2
    Update any custom form controls that need to utilize the new dirty, hidden, or pending input requirements.

Release Summary

This release introduces the [formField] directive and several enhancements to custom form controls, alongside critical bug fixes for the compiler AST, SVG security, and RouterLink behavior.
