v0.7.6

Fixed

• Antigravity voice input can no longer terminate an active coding session. Relay no longer advertises audio or transcription support to Antigravity while no explicit transcription provider has been configured. If Antigravity still sends a recording, Relay rejects it locally with a clear “voice transcription isn’t supported yet” response, keeps the session usable for the next typed message, avoids sending the recording to any configured model (and therefore avoids surprise provider charges), and redacts audio payloads from trace previews.
• Claude Code and Claude Desktop subagents now inherit the Relay model that launched them. Partner models such as Qwen, Grok, and Kimi no longer fall back to Claude Sonnet when they delegate work, preventing 400 Unknown model: claude-sonnet-... failures from providers that do not expose Anthropic models.
• Explicit subagent model choices now respect the models available in the current Relay session. When a partner model requests a favorite model for a subagent, Relay routes that child to the requested favorite; otherwise, the child inherits its parent's exact provider and model. The routing is isolated per Claude session and supports concurrent and nested subagents without leaking selections between conversations.
• Claude Code 2.1.220's restricted subagent model validation is handled transparently. Relay bridges Claude's locally accepted model aliases to session-scoped Relay routes, removes its internal routing marker before upstream requests, and leaves native Anthropic passthrough and unrelated tools unchanged.
