In an effort to provide a more powerful and stable webhook log experience, we are going to begin limiting the webhook log retention to 30 days.
The webhook logs are viewable only from the organization or repository settings UI. We currently allow users to page through webhook logs until the they reach the first delivery for that hook regardless of how old the delivery is. However, as of Friday, November 2nd, users will only be able to page back through 30 days of webhook delivery logs.
Note: This update does not affect GitHub Enterprise. The webhook log retention period on GitHub Enterprise will continue to be 8 days.
