Over the next six months, we will be making the following changes and deprecations to the GitHub Actions service:
Reduction to Webhook rate limit in GitHub Actions
Starting October 1st, 2024 we will be adding a new rate limit of 1,250 requests per 10 seconds per repository for incoming Webhook events for GitHub Actions. After monitoring usage over the past several weeks, we believe that no customers will be impacted by this change, but if you believe you will need to exceed this in the future, please reach out to GitHub support.
Cache v1-v2 deprecation
Starting February 1st, 2025, Actions’ cache storage will move to a new architecture, resulting in the deprecation of v1-v2 of actions/cache. Attempting to use a version of the action after the announced deprecation date will result in a workflow failure. Please note: if you are pinned to a specific version or SHA of the action, your workflows will also fail after February 1st. We strongly encourage you to update your workflows to begin using v3 or v4 of actions/cache as soon as possible.
This deprecation will not impact any existing versions of GitHub Enterprise Server that are currently in use. Cached entries within their retention period will remain accessible from the UI or REST API regardless of the version used to upload. This announcement will also be added to the actions/cache repository.
