 # [0.9.17](https://github.com/flextype/flextype/compare/v0.9.16...v0.9.17) (2021-XX-XX)
 
+### Features
+
+* **core** use `flextype.php` as common entry point instead of `bootstrap.php` and `dependencies.php`
+
+* **csrf** add Atomastic CSRF protection.
+
+* **macros** add `onlyFromCollection` and `exceptFromCollection` macros for Arrays ([#553](https://github.com/flextype/flextype/issues/553))
+
+* **actions** add Actions API ([#549](https://github.com/flextype/flextype/issues/549))
+
+    ### Usage
+    
+    #### Example 1
+    ```php
+    // Set new action content.create
+    flextype('actions')->set('content.create', function($id, $data) {
+      return flextype('content')->create($id, $data);
+    });
+
+    // Get action content.create
+    flextype('actions')->get('content.create')('hello-world', []);
+    ```
+
+    #### Example 2
+    ```php
+    // Set new action content.update
+    flextype('actions')->set('content.update', function($id, $data) {
+      if (flextype('entries')->update($id, $data)) {
+        flextype('logger')->info("Content {$id} successfully updated");
+        flextype('cache')->delete($id);
+      } else {
+        flextype('logger')->error("Content {$id} was not updated");
+      }
+    });
+
+    // Get action content.update
+    flextype('actions')->get('content.update')('hello-world', []);
+    ```
+
+    #### Example 3
+    ```php
+    // Set new action content.create
+    flextype('actions')->set('content.create', function($id, $data) {
+      if(flextype('registry')->get('database') == 'MySQL') {
+      // ... create new content in the MySQL database.
+      } else {
+        return flextype('content')->create($id, $data);
+      }
+    });
+
+    // Get action content.create
+    flextype('actions')->get('content.create')('blog/post-1', []);
+    flextype('actions')->get('content.create')('blog/post-2', []);
+    flextype('actions')->get('content.create')('blog/post-3', []);
+    ```
+
+    The Flextype Actions API provides new capabilities to extend the Flextype core by registering and reusing useful code snippets from global actions namespace.
+
+    _**Note:** For security reason - actions should be executable only for PHP Backend and YAML Blueprints, and no possibility to execute them in the TWIG Templates or in the Entries Content._
+
+### Bug Fixes
+
+* **htaccess** security fixes for `.htaccess`
+* **plugins** fix plugins initialization ([#551](https://github.com/flextype/flextype/issues/551))
