v0.preview.75 - 2026-08-10

Added

• Custom providers in the user catalog accept an extra_body map — provider-specific fields merged into chat and streaming request bodies, for gateways and proxies that require extra parameters. Keys that collide with Ante-owned request fields are dropped with a notice at catalog load instead of rejecting the whole provider

Changed

• SessionStart and SessionUpdated no longer carry the active provider's full model list on the wire; that catalog data is available from ante catalog. Clients still receive the provider id, display name, and effective base URL

Fixed

• Anthropic requests are compatible with proxies and gateways again: the unsupported context-management field is no longer sent, extended-thinking budgets respect the 1024-token minimum, and a temperature other than 1 with thinking enabled now fails with a clear message instead of a confusing provider error
