+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+## [0.0.1.0] - 2026-05-19
+
+### Changed
+You can now use this workshop with the latest java-webauthn-server 2.9.0 library. This upgrade brings compatibility with modern WebAuthn implementations and ensures the workshop aligns with current Yubico standards.
+
+- Upgraded java-webauthn-server from 1.2.0 to 2.9.0 across all workshop modules
+- Updated Spring Boot from 2.1.4.RELEASE to 2.7.18 (latest Java 8 compatible version)
+- Updated supporting dependencies: Lombok 1.18.46, logback-classic 1.2.13, azure-webapp-maven-plugin 2.13.0
+- Migrated deprecated APIs to java-webauthn-server 2.x standards:
+ - Removed `.icon()` usage (field removed in WebAuthn Level 2)
+ - Changed `.requireResidentKey(boolean)` to `.residentKey(ResidentKeyRequirement)`
+ - Removed `.allowUnrequestedExtensions()` (now always enabled)
+ - Removed manual attestation framework initialization (now handled internally by RelyingParty)
+
+### Added
+- BouncyCastle 1.70 dependency for EdDSA cryptographic support on Java 8
+- Comprehensive migration documentation in MIGRATION_CHANGES.md - review this if you're upgrading from v1.x
+- Code comments explaining v2.x API changes for educational purposes
+
+### Fixed
+- Completed v2.x API migration for workshop modules 2 (Credential Repository) and 4 (Authentication)
+- Preserved all Lombok annotations critical for workshop build process
+- Java 25 compatibility: Added explicit maven-compiler-plugin configuration with Lombok annotation processor paths to ensure Lombok `@Value`/`@Builder` annotations work correctly on Java 25 (stricter annotation processing requirements)
+- Cross-JDK reproducible builds: Added `maven.compiler.release=17` property to all modules, ensuring consistent compilation regardless of installed JDK version (8, 17, 21, 25, etc.)
+- Fixed Lombok `@Builder` + `@NonNull` final fields compatibility issue in U2fRegistrationResult.java by adding `@Builder(toBuilder=true)` and removing redundant field modifiers

+- **Fixed**: Removed `result.getWarnings()` usage (line 536)
+ - Warnings now logged via SLF4J instead of returned
+- **Fixed**: Removed attestation framework imports (lines 45-54)
+ - Removed: Attestation, AttestationResolver, MetadataObject, MetadataService, etc.
+- **Fixed**: Removed TrustResolver and MetadataService initialization (lines 117-127)
+ - Attestation now handled internally by RelyingParty
+- **Fixed**: Removed `.metadataService()` from RelyingParty builder
+ - Using default attestation trust configuration
+- **Fixed**: Removed attestation metadata helper methods (readPreviewMetadata, createExtraTrustResolver, createExtraMetadataResolver)
+ - No longer needed with v2.x attestation framework
+- **Fixed**: Simplified finishU2fRegistration attestation handling (lines 424-445)
+ - Removed metadataService.getAttestation() call
+ - Set attestationTrusted to false (validated by RelyingParty internally)
+ - Removed `.attestationMetadata()` from U2fRegistrationResult builder
+- **Fixed**: Updated addRegistration methods to remove attestationMetadata parameter
+ - Removed Optional attestationMetadata parameter
+ - Removed attestationMetadata from CredentialRegistration builder
+
+### data/CredentialRegistration.java
+- **Fixed**: Removed `com.yubico.webauthn.attestation.Attestation` import
+- **Fixed**: Removed `Optional attestationMetadata` field
+- **Preserved**: All Lombok annotations (@Value, @Builder, @Wither) - CRITICAL for workshop
+
+### data/U2fRegistrationResult.java
+- **Fixed**: Removed `com.yubico.webauthn.attestation.Attestation` import
+- **Fixed**: Removed `List warnings` field
+ - Warnings now logged via SLF4J
+- **Fixed**: Removed `Optional attestationMetadata` field
+- **Preserved**: All Lombok annotations (@Value, @Builder, @NonNull, @Builder.Default)
+
+## Code Changes - Module 4 (4_Authentication/complete)
+
+**Status**: COMPLETE
+- Applied same migration fixes as Module 3
+- Config.java: Removed `.icon()` usage
+- WebAuthnServer.java: All v2.x API migrations applied
+- data/CredentialRegistration.java: Removed attestationMetadata field
+- data/U2fRegistrationResult.java: Removed warnings and attestationMetadata fields
+- All Lombok annotations preserved
+
+## Code Changes - Module 2 (2_Credential_Repository/complete)
+
+**Status**: COMPLETE
+- Applied same migration fixes as Module 3
+- Config.java: Removed `.icon()` usage
+- WebAuthnServer.java: All v2.x API migrations applied
+- data/CredentialRegistration.java: Removed attestationMetadata field
+- data/U2fRegistrationResult.java: Removed warnings and attestationMetadata fields
+- All Lombok annotations preserved
+
+## Testing Required
+
+Without Maven/Java installed, the following validations are pending:
+
+1. **Build validation**: `mvn clean compile -B -Dmaven.repo.local=/tmp/m2` for each module
+2. **Test execution**: `mvn clean test -B -Dmaven.repo.local=/tmp/m2` for each module
+3. **Lombok verification**: Ensure @Builder, @Value, @Data annotations still work
+4. **End-to-end**: Start application and test registration/authentication flows
+
+## Known Issues / TODOs
+
+1. ✅ Module 4 (4_Authentication) migration fixes applied - COMPLETE
+2. ✅ Module 2 (2_Credential_Repository) migration fixes applied - COMPLETE
+3. README may reference old dependency versions - needs check
+4. Build must be tested with `mvn clean` to catch Lombok issues
+5. Initial module (initial/) only has dependency updates, no code changes needed (no webauthn usage)
+
+## Breaking Changes Reference
+
+From java-webauthn-server migration guide:
+
+1. ✅ `.icon()` fields removed
+2. ✅ `.requireResidentKey(boolean)` → `.residentKey(ResidentKeyRequirement)`
+3. ✅ `.allowUnrequestedExtensions()` removed
+4. ✅ `.getWarnings()` removed (use SLF4J)
+5. ✅ Attestation framework overhauled (MetadataService → AttestationTrustSource)
+6. ✅ `Optional` return types for getUserVerification/getResidentKey (not used in workshop)
+7. ✅ Package relocation for UVM classes (not used in workshop)
+
+## Lombok Preservation - CRITICAL
+
+All Lombok annotations MUST be preserved:
+- @Value
+- @Builder
+- @Data
+- @AllArgsConstructor
+- @RequiredArgsConstructor
+- @NonNull
+- @Builder.Default
+- @Wither
+
+**Previous failure**: Lombok annotations were removed and Maven cached old generated classes, causing build to appear successful when it wasn't. Always use `mvn clean` to prevent this.
+
+## Java 25 Compatibility
+
+### Issue
+Java 25's stricter annotation processor requirements caused Lombok `@Value`/`@Builder` annotations to fail silently when the annotation processor wasn't explicitly configured. This manifested as compilation errors:
+- `constructor RegistrationRequest cannot be applied to given types`
+- `cannot find symbol: method getRequestId()`
+
+Lombok wasn't generating constructors or getters because the annotation processor wasn't being invoked.
+
+### Fix Applied - All 3 complete/ Modules
+Added to each `pom.xml`:
+
+1. **Explicit Lombok annotation processor configuration:**
+```xml
+
+ org.apache.maven.plugins
+ maven-compiler-plugin
+
+
+
+ org.projectlombok
+ lombok
+ 1.18.46
+
+
+
+
+```
+
+2. **Maven compiler release property for reproducible cross-platform builds:**
+```xml
+17
+```
+
+This ensures consistent compilation regardless of the developer's installed JDK version (8, 17, 21, 25, etc.).
+
+### U2fRegistrationResult.java Lombok Fix
+Fixed Lombok `@Builder` + `@NonNull` final fields compatibility:
+- Added `@Builder(toBuilder = true)` annotation parameter
+- Removed explicit `private final` modifiers (redundant since `@Value` already makes fields final)
+
+This resolved the issue where `@Value` + `@Builder` with explicit modifiers on `@NonNull` fields generated a no-arg constructor stub that couldn't initialize the final fields.
+
+### Verification
+All modules now build successfully with Java 25:
+```bash
+JAVA_HOME=/opt/java-25 mvn clean test -B -f /pom.xml
+```
