The purpose of this release candidate is to give users an opportunity to
test Tomcat 8 and provide feedback to the Tomcat community. It has been
given an alpha status which means that it is not judged as being ready
for production usage. The implementations of the 4 Java EE 7
specifications are all complete but there is some internal refactoring
to be completed before the alpha label is removed.
Note: This version has 4 zip binaries: a generic one and three
bundled with Tomcat native binaries for Windows operating systems
running on different CPU architectures.
