# Changelog

## 0.10.0 (2026-07-13)

### Minor Changes

- Add `hint` field to `PaymentError` problem details. `PaymentRequiredError`, `MalformedCredentialError`, and `PaymentMethodUnsupportedError` now include a default hint pointing users to wallet documentation. (by @Osraka, [#172](https://github.com/tempoxyz/pympp/pull/172))

### Patch Changes

- Preserved MCP challenge metadata when converting MCP challenges to core payment challenges. (by @Osraka, [#172](https://github.com/tempoxyz/pympp/pull/172))
- Handle multipart (`files=`) and streaming bodies on paid 402 retry. Multipart bodies are buffered and replayed identically; async generator bodies raise `PaymentError` before any I/O. (by @Osraka, [#172](https://github.com/tempoxyz/pympp/pull/172))
- Preserve `subscriptionId` when parsing and formatting payment receipts. (by @Osraka, [#172](https://github.com/tempoxyz/pympp/pull/172))
- Fixed MCP payment error detection to support the current MCP SDK's `McpError` shape, where error code and data are nested under an `error` attribute rather than directly on the exception. Added helper functions `_error_code` and `_error_data` to extract these fields from both error shapes. (by @Osraka, [#172](https://github.com/tempoxyz/pympp/pull/172))
