Introducing toll-free numbers, expanded SMS support, and new privacy controls
Improvements to audio file support
Dashboard UI and Documentation bug fixes

New Features
Toll-free Numbers

Users can now purchase toll-free Incoming Numbers from FreeClimb. To find a toll-free number, go to your Dashboard's Buy a Number page, or use the Available Numbers API endpoint.

If using the Dashboard, users can select Toll-free from the Type dropdown, or use the Digit or Phrase search fields to find a specific set of digits or characters.

If using the API directly, users can still use query parameters for digit or character matches.

For more details on the uses and benefits of toll-free numbers, see Choosing a Number.

Expanded support for SMS

🎉 Inbound and outbound messages now support Unicode 🎉 For more details, see Guide to Encoding.
Users can now send and receive long messages. For more details, see Guide to Concatenation.

New privacy controls

Users can now obscure sensitive user data in their logs using privacyMode. For more details on how to use privacyMode, see Securing Sensitive User Data.

Improvements
Cache management for audio files

A new error message will be logged for an unacceptable audio file format.
Multi-channel audio is now supported for Play and PlayEarlyMedia PerCL commands.
FreeClimb's handling of Cache-Control headers is now RFC compliant.
