Most of the major changes were introduced in 0.9 The documentation listing the backward compatibility issues with 0.9 can be found at https://cwiki.apache.org/confluence/display/PIG/Pig+0.9+Backward+Compatibility
I believe other changes that are not listed there are the introduction of macros. A complete list of features/bug fixes/improvements by version number can be found on JIRA at https://issues.apache.org/jira/browse/PIG#selectedTab=com.atlassian.jira.plugin.system.project%3Achangelog-panel Hope this helps.
