Changes

Breaking Changes

Made the Composite decoder check for exact field count match
Dropped the Monad and MonadFail instances for it

0.14

Moved to “iproute” from “network-ip” for inet datatypes

0.13

Removed PostgreSQL.Binary.Data. Because it was causing Haddock in the dependant packages to unpredictably redirect to it instead of the original location regardless of whether they were imported from it.
