v0.5.1 — Python 3.9 compat + CI

Patch release. v0.5.0 was importable but unusable on Python 3.9 because Pydantic v2 can't evaluate X | None annotations on 3.9 without the eval_type_backport shim. v0.5.1 adds it as a conditional dependency.

Also lands the .github/workflows/test.yml workflow that the README CI badge was referencing since day one (the badge was a 404 link).

pip install eupago==0.5.1

See CHANGELOG.md for details.

v0.5.0 — Production-validated release

First production-validated release. MB WAY, Multibanco, Pay By Link and Refunds were exercised live against a real eupago production channel — 5 real payments paid and 3 refunds emitted, all webhooks captured and verified through the SDK. Several wire-shape bugs surfaced and were fixed by the way.

Highlights

• 🚀 Production-validated end-to-end for MB WAY, Multibanco, Pay By Link, Refunds
• 📋 Subscription management on the Management API — list / get / edit / revoke
• 🔗 WebhookEvent.original_transaction_id — refund webhooks now link back to the original payment
• 🔑 EupagoClient(management_bearer=...) — escape hatch while OAuth credentials are pending
• 🏦 eupago.utils.bic_for_pt_iban — BIC lookup helper covering 54 PT banks (required for Multibanco refunds)
• 🔄 client.refunds.get(refund_id) — poll refund settlement state

Wire-shape bugs fixed (discovered in prod)

• MB WAY rejected webhooks use "Canceled" (US 1-L spelling) → previously fell to PENDING
• Refund webhooks use "REFUNDED" (uppercase) and method "RB:PT" → previously dropped on the floor
• Multibanco refund requires iban AND bic (despite docs claiming bic optional) — definitively probed
• Credit Card capture body wasn't being sent correctly
• Credit Card subscription requires nested subscription block
