Fetches the raw changelog/release notes from GitHub Releases API\n2. Pulls the matching structured release notes from a **Notion** database (rich formatted content)\n3. Uses **OpenAI** to rewrite the technical changelog into a natural, podcast-style spoken script\n4. Sends the script to **ElevenLabs TTS API** to generate a professional MP3 audio file\n5. Uploads the MP3 via **UploadToURL** to get a permanent public audio URL\n6. Uses the **HTML node** to compose a beautifully formatted email newsletter with the audio player embed, changelog summary, and a 'Listen Now' CTA button\n7. Sends the newsletter via **Gmail** to your subscriber list (loaded from Google Sheets)\n8. Posts a Slack message to your internal `#product-updates` channel with the audio URL and release summary\n9. **Writes back** to the Notion changelog page \u2014 marks it as 'Audio Published' with the hosted audio URL\n\n**Architecture (unique from all previous templates):**\n- \ud83d\udc19 GitHub Trigger (watches releases \u2014 NEW trigger type)\n- \ud83d\udcd3 Notion \u2014 fetch release notes page (NEW: database query)\n- \ud83e\udd16 OpenAI \u2014 rewrite to spoken script (NEW: different prompt purpose)\n- \ud83c\udf99\ufe0f ElevenLabs TTS API \u2014 audio generation (NEW: TTS node)\n- \u2601\ufe0f UploadToURL \u2014 host the MP3 file (mandatory)\n- \ud83d\udccb Aggregate Node \u2014 bundle subscriber emails (NEW node type)\n- \ud83c\udf10 HTML Node \u2014 compose rich email body (NEW node type)\n- \ud83d\udce7 Gmail \u2014 send newsletter to subscribers (NEW: email delivery)\n- \ud83d\udcac Slack \u2014 post to #product-updates channel (NEW: Slack node)\n- \ud83d\udd04 Notion Update \u2014 write-back audio URL to source page (NEW: bidirectional)\n\n**Setup Requirements:**\n1. GitHub credentials (personal access token with `repo` read scope)\n2. Notion Integration Token \u2014 share your Changelog database with the integration\n3. Notion Database ID for your changelog (from the database page URL)\n4. OpenAI API credentials\n5. ElevenLabs API Key + your preferred Voice ID (from elevenlabs.io/voices)\n6. UploadToURL endpoint configured in upload node\n7. Gmail OAuth2 credentials\n8. Google Sheets with subscriber emails \u2014 sheet named `Subscribers` with column `Email`\n9. Slack Bot Token with `chat:write` scope \u2014 set channel to `#product-updates`\n10. Notion credentials again for the write-back step"
