# Framework crates consolidated into everruns-core and the facade > Engine, host, builtins, MCP, AG-UI, driver and contract crates merged into fewer packages, so Framework users update dependencies and imports when upgrading. Source: Date: 2026-10-04 Products: Framework Category: Breaking Available: In 0.41.0 Pull request: everruns/everruns#4035 Pull request: everruns/everruns#4077 Pull request: everruns/everruns#4081 Pull request: everruns/everruns#4083 Pull request: everruns/everruns#4084 The published crate set shrank to 37. Each old crate shipped one deprecated forwarding release before removal: * Vendor driver crates moved into `everruns-drivers`, one feature per vendor (0.35). * Provider, capability and model-profile APIs moved into `everruns-contracts` (0.37). * `everruns-platform` became `everruns-capabilities` (0.39). * Engine, host, builtins, MCP and AG-UI became `everruns-core` features (0.40), and their shims were removed in 0.41. ```toml everruns-drivers = { version = "0.41", features = ["openai"] } ``` No capability was removed, and published shim versions are not yanked.
