-Version 3.1 of the helpers is out!
+Current version: 3.1.2
 ==================================
 
-A new major version **3.1** of the helpers is now out. This version brings major changes to the way helpers internally works by using
-templates instead of the standard `tag()` and `div()` method.
+The current version of the helpers is `3.1.2`, this means that new features will not be ported to older versions (i.e. `<= 3.1.1`).
+If you are migrating from a version `< 3.1.0`, feel free to open issues if you encounter problems since version `3.1.0` brought a lot
+of changes.
 
 #### Changes
 
 - Most methods are now based on templates, meaning that:
     - Options like `tag`, `aria-*`, `data-*`, ..., have been dropped from various methods.
     - The `templateVars` options is now usable with most methods.
     - There might be escaping issue since the old `div()` and `tag()` methods did not escape content be default, while
-the template based methods do. Feel free to open an [issue](https://github.com/Holt59/cakephp3-bootstrap-helpers/issues/new) if 
+the template based methods do. Feel free to open an [issue](https://github.com/Holt59/cakephp3-bootstrap-helpers/issues/new) if
 you encounter problems with escaping.
 
 Some minor changes that do not impact the user interface:
-- The `BootstrapTrait` class has been split in two classes: `ClassTrait` and `EasyIconTrait`. 
+- The `BootstrapTrait` class has been split in two classes: `ClassTrait` and `EasyIconTrait`.
 - The test cases have been updated and strenghten to avoid bad modification in the code.
 
-#### Migrating to 3.1
-
-List of changes that need refactoring in your code:
-
-- `BootstrapHtmlHelper`
-    - The `faIcon` and `glIcon` have been dropped.
-    - The `useFontAwesome` options has been dropped, the new way is to customize the `icon` template.
-    - It is no longer possible to use custom `tag` to render labels, badges, alerts (still possible for `tooltip`).
-- `BootstrapNavbarHelper`
-    - The `autoButtonLink` options has been dropped, this was misleading for many users.
-
-Some options such as `aria-*`, `data-*`, have been dropped from various methods since these are now included in the templates,
-if you want to customize them, you should modify the template.
