I had the following code installed in my custom theme under the </head>
section:
<script type="text/discourse-plugin" version="0.8">
api.replaceIcon('d-liked', 'thumbs-up');
api.replaceIcon('d-unliked', 'thumbs-o-up');
api.replaceIcon('heart', 'thumbs-up'); // profile pages
api.replaceIcon('notification.liked', 'thumbs-up'); // notifications
</script>
Previously while on 2.5.x this was working to replace the heart, but now the custom icon is gone, and there is no heart. Has the method changed for replacing the heart? Thanks.
