Differences between Jakarta Pages 4.0 and 3.1

Many deprecated features were removed in 4.0, which warranted a major release.

New Additions:

• The ErrorData class to updated to support new Servlet 6.1 attributes jakarta.servlet.error.query_string via getQueryString and jakarta.servlet.error.method via getMethod.

Removals:

• All methods that over wrote the ELResolver.getFeatureDescriptors() (deprecated in Expression Language 5.0)
• The isThreadSafe page directive (deprecated in Pages 3.1)
• The jsp:plugin, jsp:param, and jsp:fallback actions. Browsers no longer support this functionality. (deprecated in Pages 3.1)
• jakarta.servlet.jsp.JspException.getRootCause() (deprecated in JSP 2.1)

Small comment: For Legacy JSP actions:, I would say no longer support their functionality.
