 # jQuery.filterTable Change Log
 
-### 1.5.6
+## 1.5.6
 - Fixed filtering to work for special characters `'`, `"`, and `\`.
 - Minor documentation updates.
 
-### 1.5.5
+## 1.5.5
 
 - The filtering should now trigger automatically on input on iOS. For some reason, Safari iOS triggers a `blur` event on field change but not `keyup` or other related events.
 - A new feature for extending the plugin (option `filterExpression`) has been added. The default is unchanged—the literal filter string.

 - Merged [Jason](https://github.com/deadbeef404)’s `minRows` bug fix.
 - Added an FAQ file.
 
-### 1.5.4
+## 1.5.4
 
 - Added a return key trap to the input filter field so that pressing return in the field should not submit any forms the table may be within.
 - The `preventReturnKey` option (`true` by default) has been added to allow you to switch back to the previous behavior of allowing the return key to submit forms.
 
-### 1.5.3
+## 1.5.3
 
 - **There is a potentially significant change in functionality in this version.** While the documentation offered the `inputSelector` option, within the code it was implemented as `filterSelector`. This has been corrected to match the documentation. Note that if you were previously using the `filterSelector` option to overcome this issue, you will need to change it to `inputSelector` to use the feature with this version.
 
-### 1.5.2
+## 1.5.2
 
 - Added an `inputSelector` option, thanks to [Pratik Thakkar](https://github.com/pratikt), which specifies a selector for an existing element to use instead of creating a new filter input field. There are some caveats of which to be aware:
     - If the element doesn't exist, a filter input field will be created as normal.
     - Because of quick lists and other options, this setting will be ignored and the filter input field will be created as normal if the resolution of the `inputSelector` returns more than one element.
 
-### 1.5.1
+## 1.5.1
 
 - Added an `autofocus` option, thanks to [Robert McLeod](https://github.com/penguinpowernz), which is disabled by default. Note that autofocus is generally a bad idea for accessibility reasons, but if you do not need to be compliant or don't want to support accessibility users, it's a nice user experience option.
 
-### 1.5
+## 1.5
 
 - **There is a potentially significant change in functionality in this version.** The callback is now called every time the search query changes. Previously it was only called when the change was a non-empty query. That is, the callback is now called when the query is cleared too.
 - Additional features have been taken from [Tomas Celizna](https://github.com/tomasc)'s CoffeeScript-based fork:

     - The options in the documentation have been ordered alphabetically for easier scanning.
 - The internal pseudo selector is now created appropriately according to the jQuery version. (Pseudo selector generation changed in jQuery 1.8)
 
-### 1.4
+## 1.4
 
 - Fixed a bug with filtering rarely showing rows that did not have a match with the search query.
 - Added example pages.
 - Improved inline documentation of the source code.
 
-### 1.3.1 (in spirit)
+## 1.3.1 (in spirit)
 
 - Added minified version of the plugin (thanks [Luke Stevenson](https://github.com/lucanos)).
 
-### 1.3
+## 1.3
 
 - The functionality is not reapplied to tables that have already been processed. This allows you to call `$(selector).filterTable()` again for dynamically created data without it affecting previously filtered tables.
 
-### 1.2
+## 1.2
 
 - Changed the default container class to `filter-table` from `table-filter` to be consistent with the plugin name.
 - Made the cell highlighting class an option rather than hard-coded.

 - Initial public release.
