 # v26.1.2, build 232 (2026-01-xx xx:xx UTC)
 - Added the option to hide specific assistants by configuration plugins. This is useful for enterprise environments in organizations.
 - Added the current date and time to the system prompt for better context in conversations. Thanks Peer `peerschuett` for the contribution.
+- Added error handling for context window overflow, which can occur with huge file attachments in chats or the document analysis assistant.
 - Improved error handling for model loading in provider dialogs (LLMs, embeddings, transcriptions).
 - Improved the microphone handling (transcription preview) so that all sound effects and the voice recording are processed without interruption.
 - Improved the handling of self-hosted providers in the configuration dialogs (LLMs, embeddings, and transcriptions) when the host cannot provide a list of models.
 - Improved the document analysis assistant (in preview) by allowing users to send results to a new chat to ask follow-up questions. Thanks to Sabrina `Sabrina-devops` for this contribution.
+- Improved error messages for failed communication with AI servers.
 - Fixed a logging bug that prevented log events from being recorded in some cases.
 - Fixed a bug that allowed adding a provider (LLM, embedding, or transcription) without selecting a model.
 - Fixed a bug with local transcription providers by handling errors correctly when the local provider is unavailable.
