 Changelog
 ---------
 
+#### 1.4.2 - released 2013-12-12
+
+**Patch update to remove a broken pull request** - may have consequences for users of 1.4.0 and 1.4.1 that exploited the "`find_many()` now returns an associative array with the databases primary ID as the array keys" change that was merged in 1.4.0.
+
+* Back out pull request/issue [#133](https://github.com/j4mie/idiorm/pull/133) as it breaks backwards compatibility in previously unexpected ways (see Idiorm issues [#162](https://github.com/j4mie/idiorm/pull/162), [#156](https://github.com/j4mie/idiorm/issues/156) and [#133](https://github.com/j4mie/idiorm/pull/133#issuecomment-29063108)) - sorry for merging this change into Paris - closes Idiorm [issue 156](https://github.com/j4mie/idiorm/issues/156)
+
 #### 1.4.1 - released 2013-09-05
 
 * Increment composer.json requirement for Idiorm to 1.4.0 [[michaelward82](https://github.com/michaelward82)] - [Issue #72](https://github.com/j4mie/paris/pull/72)
