4.0.0 - Major Release

This is a major release with breaking changes. The library has been upgraded to Spring Boot 4.x and Jakarta EE 10. For applications still on Spring Boot 3.x, compatibility modules are provided. Please check the 4.0 Migration Guide for comprehensive upgrade instructions

⚠️ BREAKING CHANGES

Spring Boot and Jakarta EE Version Upgrades

• Spring Boot: Upgraded from 3.x to 4.0.3
• Spring Framework: Upgraded from 6.x to 7.0.5
• Spring Security: Upgraded from 6.x to 7.0.3
• Jakarta Servlet API: Upgraded from 6.0.0 to 6.1.0
• Java: Minimum version remains Java 17
• JUnit Jupiter: Upgraded from 5.12.2 to 6.0.3

HTTP Client Default Changed

Token-client module now uses Java 11's HttpClient as the default implementation. Apache HttpClient 4 remains available as a dependency for backward compatibility.

Impact:

• ✅ No code changes required if you use the default (parameterless) constructors
• ⚠️ Deprecated constructors added for backward compatibility with Apache HttpClient 4
• ❌ Will be removed in version 5.0.0 - Plan to migrate to Java HttpClient or custom implementation

Deprecated in 4.0.0 (Removed in 5.0.0):

• DefaultOAuth2TokenKeyService(CloseableHttpClient)
• DefaultOAuth2TokenService(CloseableHttpClient)
• DefaultOAuth2TokenService(CloseableHttpClient, TokenCacheConfiguration)
• DefaultOidcConfigurationService(CloseableHttpClient)
• HttpClientFactory interface and DefaultHttpClientFactory implementation

Migration Path:

• Option 1 (Recommended): Use default constructors - Java 11 HttpClient is used automatically
• Option 2 (Temporary): Continue using deprecated constructors with Apache HttpClient 4
• Option 3 (Custom): Implement SecurityHttpClientFactory interface for custom HTTP clients (see CUSTOM_HTTPCLIENT.md)

See the comprehensive Apache HttpClient Migration Guide for detailed migration instructions.
