+* 2.0.0-alpha3 (for early testing; 2021-03-13)
+  * Change coordinates to `com.github.seancorfield/honeysql` (although new versions will continue to be deployed to `seancorfield/honeysql` for a while -- see the [Clojars Verified Group Names policy](https://github.com/clojars/clojars-web/wiki/Verified-Group-Names)).
   * Support much richer range of syntax on `CREATE`/`DROP` statements in general, including columns, `TABLESPACE`, `CASCADE`, `WITH [NO] DATA`, etc.
   * Fix #306 by supporting `CREATE TABLE .. AS ..`.
   * Fix #305 by supporting more complex join clauses.

   * Reconcile `where` behavior with recent 1.0 changes (porting #283 to v2).
   * Fix #280 by adding `:escape` as special syntax for regular expression patterns.
   * Fix #277 by adding `:join-by`/`join-by` so that you can have multiple `JOIN`'s in a specific order.

 * 2.0.0-alpha2 (for early testing)
   * Since Alpha 1, a lot more documentation has been written and docstrings have been added to most functions in `honey.sql.helpers`.
   * Numerous small improvements have been made to clauses and helpers around insert/upsert.

   * This is a complete rewrite/simplification of HoneySQL that provides just two namespaces:
     * `honey.sql` -- this is the primary API via the `format` function as well as the various extension points.
     * `honey.sql.helpers` -- provides a helper function for every piece of the DSL that is supported out-of-the-box.
-  * The coordinates for HoneySQL 2.0 are `seancorfield/honeysql` so it can be added to a project that already uses HoneySQL 1.0 without any conflicts, making it easier to migrate piecemeal from 1.0 to 2.0.

 In addition, HoneySQL 2.x contains different namespaces so you can have both versions on your classpath without introducing any conflicts. The primary API is now in `honey.sql` and the helpers are in `honey.sql.helpers`. A Spec for the DSL data structure will be available in `honey.specs` at some point (work in progress).
