 ### pg@8.2.0
 
-- Switch internal protocol parser & serializer to [pg-protocol](https://github.com/brianc/node-postgres/tree/master/packages/pg-protocol). The change is backwards compatible but results in a significant performance improvement across the board, with some queries as much as 50% faster. This is the first work to land in an on-going performance improvment initiative I'm working on. Stay tuned as things are set to get much faster still! :rocket:
