The Wikipedia Library Echo notification (T132084) is ready for deployment, and will be rolled out with a gradually decreasing edit count requirement for receiving it. This is because, per T271962, approximately 40,000 editors may receive this notification in the first week if it was deployed with the target requirements and we don't want to substantially degrade tool performance.
Pending any issues or bugs, we will follow this deployment plan:
| **Date** | **Edit count threshold** | **Approximate number of editors receiving notification**
| 8 November | 50,000 (Meta and Test only) | 50,000 | Unknown (low)
| ASAP | 50,000 | 5,249
| ASAP + 1 week | 10,000 | 9,862
| ASAP + 2 weeks | 2,000 | 12,259
| ASAP + 3 weeks | 500 | 11,771
