+## [3.1.0] - 2022-02-01
+
+### Added
+
+- Added two methods that will make libs work with WP 5.8+ and older versions
+
+WP 5.8 made a breaking change in two hooks `block_categories` -> `block_categories_all` and `allowed_block_types` -> `allowed_block_types_all`.
+
+Implementation:
+
+```php
+// Create new custom category for custom blocks.
+if (\is_wp_version_compatible('5.8')) {
+    \add_filter('block_categories_all', [$this, 'getCustomCategory'], 10, 2);
+} else {
+    \add_filter('block_categories', [$this, 'getCustomCategoryOld'], 10, 2);
+}
+
+// Only allow custom-built blocks.
+if (\is_wp_version_compatible('5.8')) {
+    \add_filter('allowed_block_types_all', [$this, 'allowOnlyCustomBlocks'], 21, 2);
+} else {
+    \add_filter('allowed_block_types', [$this, 'allowOnlyCustomBlocksOld'], 21, 2);
+}
+```
