# v26.7.1, build 243 (2026-07-05 16:39 UTC)
- Added the assistant builder as a beta preview feature for generating and installing assistant plugins. This no-code environment is designed so anyone can create assistants without needing a computer science background. To try it, enable preview features in the app settings and then explicitly enable the Assistant Builder feature. Thanks, Nils Kruthoff (`nilskruthoff`), for this extraordinary contribution.
- Added expert capability overrides for providers, so advanced users and configuration plugins can manually adjust selected model capabilities, including reasoning (thinking) behavior, when automatic detection needs adjustment.
- Added configuration plugin options for default chat data source behavior and the related data source selection and validation agents.
- Added support for organization-approved assistant plugins, so trusted assistant plugins can be enabled without requiring each user to run a separate security audit.
- Added support for assistant plugin tiles that can open a chat directly in a chosen workspace.
- Improved the provider selection by showing small capability icons for supported audio, image, speech, and reasoning features of the selected model.
- Improved PDF file handling in Flatpak builds by supporting the standard Flatpak library location for PDFium and adding clearer diagnostics for troubleshooting PDF loading.
- Improved source links in chat answers when file or document names contained spaces, umlauts, or other special characters. Source entries now open much more reliably for documents with names such as PDFs from shared portals or internal knowledge bases.
- Improved all assistants, so running tasks can continue when you leave the assistant and return later.
- Improved the assistant overview so it shows which assistants are still running or have a result ready.
- Improved the activity indicators for running chats and assistants so they use a consistent blue highlight.
- Improved the chat experience by automatically focusing the message composer again when it becomes available. Thanks, Dominic Neuburg (`donework`), for the contribution.
- Improved the chat message formatting so line breaks in responses are preserved more closely, making structured text easier to read. Thanks, Dominic Neuburg (`donework`), for the contribution.
- Fixed configuration plugins so they can configure assistant plugin audit settings, including required audit levels, audit provider selection, and automatic background audits.
- Fixed default data source selection so sources that require local or trusted providers are selected again after switching from a cloud provider to a suitable provider.
- Upgraded Rust to v1.96.1
