 Only accretive/fixative changes will be made from now on.
 
 * 1.2.next in progress
+  * Address [#207](https://github.com/seancorfield/next-jdbc/issues/207) by supporting "db-spec" hash maps containing `:datasource` or `:connection-uri` (this is otherwise undocumented and intended to aid migration from `clojure.java.jdbc`).
   * Address [#199](https://github.com/seancorfield/next-jdbc/issues/199) by adding notes on UTC usage -- [@denismccarthykerry](https://github.com/denismccarthykerry).
   * Enhance `insert-multi!` to accept a sequence of hash maps and also to support batch execution, via PR [#206](https://github.com/seancorfield/next-jdbc/pull/206) -- [@rschmukler](https://github.com/rschmukler).
   * Fix HikariCP pooling example.
