* Updated changelog
* Update version number of between to 3.1.0
* added PostgreSQL.JSON module
* finished adding all JSON operators
* cleanup
* half way through writing tests
* final tweaks to comments
* finished with JSON tests
* upped persistent dependency to 2.10.0 because of PersistArray data constructor addition needed for JSON operators
* noticed the minus operator with text[] as right operand was only added in PSQL v10, added function and adjusted types/tests
* adjusted yaml configs for updated dependencies and PSQL v10 in Travis
* try to get PostgreSQL 10 running
* use @since notation
* removed postgresql from 'services' field
* and one more time, with FEELING! (and postgresql-10)
* foo
* PSQL 10 runs on 5433, it seems? reverting .travis.yml changes and setting test conn to port 5433
* of course I forget to add the PORT env > .<
* doop-dee-doo
* herp-a-derp
* last commit (hopefully)
* also have more recent dependencies in the 'compiler should error' tests
* why does it feel like this'll go on for a while still?
* copied some extra-deps from the persistent ymls
* aaaaand we're done... right?
* added persistent-postgresql to the dependencies and used its instances for Aeson.Value
* small comment fix
* moved the instances to their own module, this way they're optional to use if you don't use persistent-postgresql
* use port 5432, like a normal PostgreSQL!
* added JSONB newtype with instances, instead of orphaning Aeson.Value
* reworked everything to use the JSONB newtype. And adjusted most comments to reflect the change
* fixed all the tests (just making it compile again)
* that's right, Travis' PSQL v10 NEEEEDS it to be port 5433... for some reason
* update on the haddockumentation
* added JSONAccessor data type for easier usage of certain operators
* Also add to changelog.md
* JSONExpr -> JSONBExpr
* this damn PGPORT is really irritating
