The minimum required Java version for Axis2 has been changed to Java 8.
The Apache Commons HttpClient 3.x based HTTP transport has been removed.
The HTTPClient 4.x based transport has been upgraded to use the APIs supported by the latest HTTPClient version.
To improve dependency management, the data binding JARs have been split to separate the code required at build time from the code required at runtime:
axis2-jibx has been split into axis2-jibx and axis2-jibx-codegen.axis2-xmlbeans has been split into axis2-xmlbeans and axis2-xmlbeans-codegen.axis2-jaxbri has been renamed to axis2-jaxbri (The JAXB-RI data binding doesn't require any additional classes at runtime).
