+# Changelog
+
+## 2.0.0 (2026-07-22)
+
+### Breaking Changes
+- Complete rewrite with modern tooling and API design
+- `PaydunyaClient(master_key, private_key, token, mode="test"|"live")` replaces
+  the old `paydunya.debug` and `paydunya.api_keys` module-level globals
+- **OPR removed** — the `opr/create` and `opr/charge` endpoints no longer exist
+  in PayDunya's current documentation. Use the JavaScript-based PSR flow
+  (documented at https://developers.paydunya.com/doc/EN/psr_plugins/api_psr)
+  where your server creates a checkout invoice and returns the token
+- **Pydantic v2** — all models (`Store`, `InvoiceItem`, `Customer`, `Tax`,
+  `Actions`) are now Pydantic `BaseModel` classes with built-in validation
+  (email format via `EmailStr`, amount bounds, positive quantity, required
+  fields). Invalid input raises `ValidationError` at the SDK boundary instead
+  of being sent to the API.
+- Python 3.10+ only (dropped all Python 2 and Python < 3.10 support)
+- `httpx` replaces `requests`
+
+### Added
+- **DMP API** — Payment Request API: send invoices via SMS/Email
+  (`DMP.create()` / `DMP.check_status()`)
+- **IPN helper** — `verify_ipn_hash()` for SHA-512 hash verification on callbacks
+- **Customer pre-fill** — `Invoice.set_customer(name, email, phone)` to pre-fill
+  payment page fields
+- **Docs-compliant items format** — items now keyed as `item_0`, `item_1`, ...
+  matching the official HTTP/JSON documentation
+- **Sandbox E2E example** — `examples/sandbox_e2e.py` with interactive
+  payment confirmation polling
+- Type hints throughout, `py.typed` marker
+- Pytest-based test suite with httpx mocking (no network required)
+- MkDocs Material documentation in `docs/`
+
+### Changed
+- Package layout: `src/paydunya/` (PEP 621)
+- Build system: hatchling instead of setuptools/setup.py
+- Linting: ruff replaces flake8/pep8/pyflakes
+- CI: GitHub Actions replaces Travis CI
+- uv for dependency management
+
+## 1.0.7
+- Last stable release under the old architecture
