 # v26.6.3, build 243 (2026-06-xx xx:xx 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.
