# 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.
