Dear Wiki user,

The "Pig070IncompatibleChanges" page has been changed by PradeepKamath.
http://wiki.apache.org/pig/Pig070IncompatibleChanges?action=diff&rev1=17&rev2=18

--------------------------------------------------

  This functionality was added to deal with gap in Pig's early functionality - lack of numeric
comparison in order by as well as lack of descending sort. This functionality has been present
in last 4 releases and custom comparators has been depricated in the last several releases.
They functionality is removed in this release.
  
  == Merge Join ==
- In Pig.0.6.0 there was a pre-condition for merge join: "The loadfunc for the right input
of the join should implement the SamplableLoader interface" - this condition is no longer
required in Pig 0.7.0. All other pre-condtions still hold.
+ In Pig.0.6.0 there was a pre-condition for merge join: "The loadfunc for the right input
of the join should implement the !SamplableLoader interface" - instead the !LoadFunc should
now implement !OrderedLoadFunc interface in Pig 0.7.0. All other pre-condtions still hold.
