+### Notable changes
+
+**SECURITY — Userland exception filtering**
+

+
+Userland exception thrown in a constructor will not be automatically caught by
+the mapper anymore. This prevents messages with sensible information from 
+reaching the final user — for instance an SQL exception showing a part of a 
+query.
+
+To allow exceptions to be considered as safe, the new method
+`MapperBuilder::filterExceptions()` must be used, with caution.
+
+```php
+final class SomeClass
+{
+    public function __construct(private string $value)
+    {
+        \Webmozart\Assert\Assert::startsWith($value, 'foo_');
+    }
+}
+
+try {
+    (new \CuyZ\Valinor\MapperBuilder())
+        ->filterExceptions(function (Throwable $exception) {
+            if ($exception instanceof \Webmozart\Assert\InvalidArgumentException) {
+                return \CuyZ\Valinor\Mapper\Tree\Message\ThrowableMessage::from($exception);
+            }
+
+            // If the exception should not be caught by this library, it
+            // must be thrown again.
+            throw $exception;
+        })
+        ->mapper()
+        ->map(SomeClass::class, 'bar_baz');
+} catch (\CuyZ\Valinor\Mapper\MappingError $exception) {
+    // Should print something similar to:
+    // > Expected a value to start with "foo_". Got: "bar_baz"
+    echo $exception->node()->messages()[0];
+}
+```
+
+**Tree node API rework**
+
+The class `\CuyZ\Valinor\Mapper\Tree\Node` has been refactored to remove access
+to unwanted methods that were not supposed to be part of the public API. Below 
+are a list of all changes:
+
+- New methods `$node->sourceFilled()` and `$node->sourceValue()` allow accessing
+  the source value.
+
+- The method `$node->value()` has been renamed to `$node->mappedValue()` and 
+  will throw an exception if the node is not valid.
+
+- The method `$node->type()` now returns a string.
+
+- The methods `$message->name()`, `$message->path()`, `$message->type()` and 
+  `$message->value()` have been deprecated in favor of the new method 
+  `$message->node()`.
+
+- The message parameter `{original_value}` has been deprecated in favor of
+  `{source_value}`.
+
+**Access removal of several parts of the library public API**
+
+The access to class/function definition, types and exceptions did not add value 
+to the actual goal of the library. Keeping these features under the public API 
+flag causes more maintenance burden whereas revoking their access allows more 
+flexibility with the overall development of the library.

+### ⚠ BREAKING CHANGES
+

+* Refactor tree node API ([d3b1dc](https://github.com/CuyZ/Valinor/commit/d3b1dcb64ec561cdedffe5ca779341fc9452a858))
+* Remove API access from several parts of library ([316d91](https://github.com/CuyZ/Valinor/commit/316d91910d289780a7b791f17b958eae264a6296))
+* Remove node visitor feature ([63c87a](https://github.com/CuyZ/Valinor/commit/63c87a2cc4c28546f28d51998a93fe89f0885535))
+
+### Bug Fixes

+* Process invalid type default value as unresolvable type ([7c9ac1](https://github.com/CuyZ/Valinor/commit/7c9ac1dd6d518e5e5f0fc02ee172b12084082d1d))
+* Properly display unresolvable type ([3020db](https://github.com/CuyZ/Valinor/commit/3020db20bfa8322e3cb198487851bb5d43ea9894))
+
+### Other
+
+* Ignore `.idea` folder ([84ead0](https://github.com/CuyZ/Valinor/commit/84ead04f84118d18ad0c557db909b0cd10b65252))
