+
+It took us a couple of months, but here we are. Lumberjack v19 is out, which brings compatibility with Angular 19 and removes the old and depricated Enum-based levels.
+
+## Angular 19
+
+With the new version of Angular out, we are happy to announce that Lumberjack is compatible with Angular 19.
+
+This closes issue: [#213](https://github.com/ngworker/lumberjack/issues/213)
+
+## Enum-based levels removal
+
+In version 17, we deprecated the usage of Enum-based levels in favor of string literal unions and announced they would be removed in version 19. See [here](https://ngworker.github.io/lumberjack/blog/announcing-lumberjack-v17). Mission accomplished.
+
+This change simplifies the API and reduces the library bundle size.
+
+## Wrapping Up
+
+There is nothing else to add; update your dependencies and enjoy the new version of Lumberjack.
