Performance improvements for the organizational feed

Rolled up push events grouping

What’s changing?

As part of our effort to help optimize activity feed load times and reduce timeouts, we’re migrating the organizational feed to a newer infrastructure. This migration from our existing system to an improved infrastructure will enable us to have a more performant experience for all users interacting with the organizational feed.

While this change is primarily back end, with minimal impact to the user experience, organizational feed users may notice a slight change to the UI. In our current experience, push event activity notifications have one line per event, mixed in with other event types in the feed. With this improvement, users can see all push events grouped into one card, sorted in chronological order with the most recent events appearing first.

Push events grouping unfurled

When is the change occurring?

This change will occur on April 21st, 2025 for all users that interact with the organizational feed.

Where can I experience this?

You can see these changes on the organizational feed.
