It filters the feed entries down to recent, relevant release items, removes noisy matches, then normalizes and groups the results into an HTML email digest. If there are releases to report, it sends the digest using Resend.\n\n### Setup steps\n\n- Configure the Schedule Trigger with the desired run frequency.\n- Update the List of RSS Feeds code node with the RSS sources to monitor.\n- Review the filtering code nodes to ensure the recency window, development build criteria, and noise words match your needs.\n- Set up valid Resend credentials and configure the sender, recipient, and subject fields in the email node.\n\n### Customization\n\nAdjust the RSS feed list, release filtering rules, grouping logic, and HTML template to tailor the digest content and formatting."
