There are more changes under the radar, but at least these needs to be ported:

• Improve screen reader text readability for project descriptions maui-samples#648
• Improve project name and clear button visibility maui-samples#649
• Improve screen reader accessibility for Add button maui-samples#650
• Fix for VoiceOver doesnot announces ComboBox and State of the ComboBox and Tab Navigation doesnot works on SfTextInputLayout  maui-samples#651
• Fixed Delete Button Visibility When Creating a New Project maui-samples#652
