# Changelog

> Notable changes to the StellarX402 facilitator, SDKs, and the Bazaar.

All dates are UTC. Semantic versioning applies to the SDKs and to the facilitator's public HTTP surface. The Bazaar's internal ranking is a black-box signal and can change without a version bump.

## Unreleased

* **Bazaar:** Explain-mode debug block on `/discovery/search`.
* **Docs:** Restructured into three-path (buyers, sellers, operators) layout.

## Facilitator 0.4.0

* **Added:** `upto` scheme support end-to-end.
* **Added:** `POST /discovery/publish` for MCP tools.
* **Changed:** `/settle` is now idempotent by `PaymentPayload`.
* **Fixed:** Sponsor balance metric was reported in stroops, now XLM.

## Facilitator 0.3.0

* **Added:** Bazaar discovery layer (`/discovery/resources`, `/discovery/search`).
* **Added:** `describe` block in `PaymentRequirements`.
* **Changed:** `/verify` returns structured `invalidReason` codes (previously free-text messages). See [Error & Rejection Codes](/reference/error-codes).
