![Auto-overage toggle on a subaccount's Limits & Capabilities tab](https://storage.googleapis.com/granular-changelog/doc-images/autoverage-subaccounts.png)

Parent accounts now control whether a subaccount can call past its included minutes. Turn on [Auto-overage](/limits-and-capabilities#auto-overage) and the extra minutes are billed to your account at your per-minute rate.

## 200 voices for Synthflow TTS

[Synthflow TTS](/voice-configuration#synthflow-tts) now offers 200 voices instead of 12, so you can match a voice to your brand instead of settling for the closest fit. Filter the **Voice** selector by accent, gender, or language, and play a preview before you assign one. Voices already on your agents are unchanged.
