Pig Developers,
We have made several significant performance and other improvements over the last couple of months: (1) Added an optimizer with several rules (2) Introduced skew and merge joins (3) Cleaned COUNT and AVG semantics I think it is time for another release to make this functionality available to users. I propose that Pig 0.4.0 is released against Hadoop 18 since most users are still using this version. Once Hadoop 20.1 is released, we will roll Pig 0.5.0 based on Hadoop 20. Please, vote on the proposal by Thursday. Olga
