The document discusses Java EE 8 and the adoption of JSR 374 (JSON Processing) and JSR 371 (Model-View-Controller). Key points include: - Java EE 8 will focus on HTML5/web enhancements, ease of development, and cloud infrastructure. - JSR 374 (JSON Processing 1.1) will be adopted, keeping the JSON processing spec up-to-date and adding editing operations. - JSR 371 (MVC 1.0) will be adopted, incorporating action-based MVC into the Java EE platform. - The tentative release schedule has early drafts in 2015, public reviews in late 2015, and a final release in early 2017
