+# SumUp Terminal for WooCommerce 0.0.9
+
+## Highlights
+
+- Adds a hybrid SumUp SDK integration: sites running PHP 8.2+ use the prefixed official `sumup/sumup-php` SDK for supported reader operations.
+- Keeps WordPress HTTP as the compatibility client for PHP 7.4-8.1, so the plugin PHP requirement remains PHP 7.4+.
+- Adds a settings status card that explains whether the official SDK or WordPress HTTP compatibility client is active.
+
+## Changes
+
+- Removed the unused `sumup/sumup-ecom-php-sdk` dependency.
+- Bundled a prefixed copy of the official SumUp PHP SDK and guarded its autoloader so PHP versions below 8.2 never parse SDK files.
+- Split reader API transport code behind a shared client interface, with SDK calls falling back to the WordPress HTTP client on SDK exceptions.
+- Added SDK reader response normalization to preserve the existing array shape consumed by the gateway.
+- Added activation/runtime guards for unsupported PHP versions below the plugin minimum.
+- Documented the SDK/compatibility-client decision in `docs/adr/0001-sumup-sdk-hybrid.md`.
+- Included regression coverage for activation, conditional SDK autoloading, compatibility messaging, pairing payloads, and SDK reader normalization.
+
+## Compatibility notes
+
+- Minimum plugin runtime remains PHP 7.4.
+- The official SumUp SDK path is active only on PHP 8.2+ when the bundled prefixed SDK is available.
+- Sites on PHP 7.4-8.1 continue to use the WordPress HTTP compatibility client; payments can still work normally.
