 - Improved the ID handling for configuration plugins.
 - Improved error handling, logging, and code quality.
 - Improved error handling for Microsoft Word export.
+- Improved file reading, e.g. for the translation, summarization, and legal assistants, by performing the Pandoc validation in the first step. This prevents unnecessary selection of files that cannot be processed.
 - Fixed a bug in the local data sources info dialog (preview feature) for data directories that could cause the app to crash. The error was caused by a background thread producing data while the frontend attempted to display it.
 - Fixed a visual bug where a function's preview status was misaligned. You might have seen it in document analysis or the ERI server assistant.
 - Fixed a rare bug in the Microsoft Word export for huge documents.
