 * `#sql/inline nil` should produce `NULL`. Fix #221. (@seancorfield)
 * `#sql/inline :kw` should produce `"kw"`. Fix #224 via PR #225. (@vincent-dm) Note: this introduces a new protocol, `Inlinable`, which controls inline value rendering, and changes the behavior of `#sql/inline :foo/bar` to produce just `"bar"` (where it was probably invalid SQL before).
 * Alias expressions `[:col :alias]` are now checked to have exactly two elements. Fix #226.
+* Allow `where` and `merge-where` to be given no predicates. Fix #228.
