AI changelog alerts where you work

Slack, in one minute (free)

Add Slack's RSS app to your workspace (all plans), then type this in the channel:

/feed subscribe https://changelogradar.vercel.app/feeds/act-now.xml

Any product feed works the same way, for example https://changelogradar.vercel.app/feeds/claude-code.xml. Slack's RSS app only posts items dated after the last one it saw, and each change keeps its vendor's date, so a change verified a few days late can be skipped. For every change, use the GitHub Action or Pro.

GitHub Action: Slack, Discord, Teams or a webhook

Free and self-hosted: it runs in your own repository with your own webhook secret and remembers what it already sent. Slack, Discord, Teams (Workflows: Send webhook alerts to a channel) or any https endpoint.

Calendar

retirements.ics adds every model shutdown date to Google Calendar, Outlook or Apple Calendar, with a reminder 7 days before in Outlook and Apple Calendar.

Data and webhooks

Every verified change as JSON: changes.json. Model retirements: retirements.json (CC BY 4.0). Each feed entry carries two <category> elements: the change type and the product slug.

A webhook receives this JSON. With a secret, each request carries X-ChangelogRadar-Timestamp and X-ChangelogRadar-Signature: sha256=HMAC-SHA256(secret, timestamp + "." + body). Compare it in constant time, reject timestamps more than 5 minutes old, and ignore a delivery id you have already seen.
