🤖 I have created a release beep boop

6.0.0 (2026-02-23)

⚠ BREAKING CHANGES

• promote v6.0.0-rc.2 to v6.0.0 stable
• Fully generated WebSocket clients for Listen v1/v2, Speak v1, and Agent v1, replacing all hand-rolled WebSocket code from v5
• Simplified send methods: send_media() accepts raw bytes directly, control messages use dedicated methods (send_keep_alive(), send_finalize(), send_flush()) instead of generic send_control()
• New domain-specific type system (deepgram.listen.v1.types, deepgram.agent.v1.types) replacing shared barrel imports from deepgram.extensions.types.sockets
• Agent settings types renamed to match generated schema hierarchy (e.g. AgentV1SettingsMessage → AgentV1Settings)

Features

• promote v6.0.0-rc.2 to v6.0.0 stable (34f543e)
• feat!: v6.0.0 stable — fully generated SDK with WebSocket support
• Custom WebSocket transport support for alternative runtimes
• TextBuilder class for TTS pronunciation and pause controls
• SageMaker transport extracted to separate deepgram-sagemaker package
• 22 production-ready examples covering auth, transcription, voice agents, TTS, text intelligence, and management APIs
• CI matrix testing across Python 3.8–3.13
