# @armory-sh/middleware-express-v4

Full package changelog.

## Unreleased

### Patch Changes

* Added deterministic facilitator routing precedence for mix-and-match network/token/facilitator setups.
* Fixed per-token facilitator resolution on shared chains to avoid wrong facilitator selection.
* Added facilitator capability-based extension filtering in payment challenge headers (fail-open: unsupported keys are auto-ignored).
* Added facilitator-aware pricing selection for middleware config flows (`network + token + facilitator` before fallback).
