2.21 Focus on the upgrade to Java 8
► Pros:● New attractive language features ● New APIs (Date and Time, ...)● Improved security● Java 7 is no more publicly supported since April 2015● Available on all platforms
► Cons:● Some organisations might still be locked to Java 7● No more ODBC driver (but a beta workaround is already
available in JDemetra+)
