# Fixes #33

Prepare the Python SDK for a 1.1.0 release.

### Summary

- Bump `trolleyhq` package version to `1.1.0` and require
`requests>=2.32.0`.
- Add generic authenticated `Gateway.request` / `Client.request` for
currently untyped API endpoints.
- Add Trust verification gateway helpers and `trust` alias.
- Add documented endpoint aliases/path construction so SDK surface audit
can cover all public API operations.
- Preserve the public method names and argument order introduced/used by
this PR while adding aliases/options for docs coverage.
- Add documented response attributes for payment, offline payment,
recipient account, and invoice payment models.
- Add optional `batch_id` support to `invoice_payment.create`,
preserving the existing list input used in this PR.
- Update CI to run all unit tests with coverage instead of the previous
command that collected no tests.
