Experimental Feature Index¶

This page lists all public API components that are currently marked as experimental in EVerest. It is at least updated with every stable release.

Experimental components are part of the public API surface but are exempt from the stability guarantees and the deprecation period. They may change in incompatible ways or be removed in any release, outside the normal deprecation process. See Experimental Components for how they are marked, promoted and removed, and Active Deprecation Index for components that are on the way out rather than on the way in.

With every stable release the maintainers review this list and decide, per component, whether to promote it to stable, keep it experimental, or remove it.

The manager options below are documented in full in Manager Command Line Options, and the manager logs a warning at startup naming any experimental option it was given.

Component	Experimental since	Notes
`manager --graceful-shutdown`	2026.10.0	Opt-in graceful module shutdown. Without it, module processes are terminated immediately on shutdown, restart and crash.
`manager --into-idle`	2026.10.0	Boot into Idle without starting modules, keeping the configuration API available.
`manager --recover-module-crashes`	2026.10.0	Bounded automatic module restart after an unexpected module exit.
`manager --reset-from-yaml`	2026.10.0	Discard the database slot and re-seed it from the YAML config. Intended for development use.
`manager --idle-on-failure`	2026.10.0	Stay alive in Idle when there is nothing startable, instead of exiting with an error.
