Markdown version of <https://harbyn.com/changes/twilio/2026-09-23-conference-list-endpoint-will-default-to-in-progress-conferences-only-on-septemb>.

Breaking change - Twilio. medium severity. In effect.

Starting September 30, 2026, GET /2010-04-01/Accounts/{AccountSid}/Conferences.json without a Status filter returns only in-progress conferences instead of all. Apps that read completed conferences must add Status=completed and make two requests to get both.

The deadline passed on Sep 30, 2026.
