* 2.0.next in progress
* Fix #367 by supporting parameters in subexpressions around `IS NULL` / `IS NOT NULL` tests.
* Address #366 by introducing `:values-default-columns` option to control whether missing columns are treated as `NULL` or `DEFAULT` in `:values` clauses with sequences of hash maps. TODO: NEEDS DOCUMENTATION UPDATES INCLUDING EXAMPLE USAGE!
* Fix #365 -- a regression from 1.x -- where subclauses for `UNION`, `EXCEPT`, etc were incorrectly parenthesized.
* Update `build-clj` to v0.5.0.
