Spring Boot is deprecating RestTemplate across its entire ecosystem, forcing a migration to RestClient as the Framework itself moves on [ref:1].

Stéphane Nicoll has deprecated RestTemplateAutoConfiguration, RestTemplateBuilder, and the full stack of RestTemplate-related customizers [1], aligning Boot with Spring Framework 7.1's removal roadmap. This is the end of an era for a widely-adopted HTTP client that shaped a generation of Spring applications. Separately, Spring Framework tightened MimeType parsing for RFC compliance [2], rewriting the entire parser as a state machine to handle quoted and unquoted parameter values correctly, improving both robustness and performance. Over in Spring AI, image generation support landed for Google GenAI [3], introducing a new spring-ai-google-genai-image module with GoogleGenAiImageModel, alongside the fixes needed to stabilize the new feature [4], [5], [6]. Boot also cleaned up deprecated APIs from the 4.2 cycle [7] while polishing deprecation messaging for HttpMessageConverters, which couldn't be marked for removal without breaking patch compatibility [8].

Action items

→ Plan RestTemplate to RestClient migration before next Spring Boot release cycle spring-projects/spring-boot [plan]
→ Test MimeType parsing changes if you rely on parameter value comparison in content negotiation spring-projects/spring-framework [monitor]
→ Evaluate Google GenAI image generation if you build AI features spring-projects/spring-ai [monitor]
