+- Added the writing style "Changelog" to the rewrite & improve text assistant. This helps to create changelogs for your projects.
+- Added an option to load PDF files directly into the translation, text summarization, and legal check assistants as a preview prototype for testing before release.
+- Added more text content to the localization system.
+- Improved the model selection for OpenAI by removing all `o1-pro` models. These models cannot be used right now, since OpenAI introduced a new API, which is not yet supported by MindWork AI Studio.
+- Improved the internal plugin maintenance so that removed resources are now removed from the file system.
+- Improved the app settings to apply the chosen language immediately.
+- Improved chat name generation to prevent the inclusion of line breaks, tabs, and other special characters.
+- Fixed an issue where empty lines in source code were being ignored by the Markdown renderer. Thanks My Nihongo for fixing this bug in the `MudBlazor.Markdown` repository.
+- Fixed the localization assistant not being able to load the localization file when used in the release app.
+- Fixed the localization of the navigation component.
+- Upgraded Rust & .NET dependencies.
