New Features

​
Export Project

Project export has been enhanced with granular component selection. You can now include any combination of agents, custom tools, Smart Tables, actions, documents, interfaces, output templates, and Knowledge Base content — or export everything at once. This makes it easier to promote agents and related configuration from one environment to another, whether you need a full project snapshot or a targeted export of only what you want to move.

Improvements

​
Agent Memory Approved Filter

The All Users filter on the Approved memories tab now displays user names instead of user IDs, making it easier to review and manage memories by person.

​
Model Deprecation Notices

EKB now announces upcoming model removals more clearly, so teams have advance notice before deprecated models are retired from the model selector.

​
Resolved Issues

  • Public chatbot disclaimer text field now expands to fit longer statements instead of concatenating text into a single line
  • Adding steps in existing workflows is more reliable — new steps align correctly within the flow, the + add-step control responds consistently between nodes and at the end of the canvas, and existing steps are no longer unintentionally removed when inserting a new step
  • Custom tool version history notes now save correctly
  • The Create Smart Table workflow node validates and creates tables correctly
  • Long-running workflows no longer fail prematurely when processing exceeds the 20-minute limit
  • REST API actions now support sending nested JSON objects and file attachments together in a multipart/form-data request body
  • Google account connections complete successfully during OAuth setup

Claude Sonnet 4 - Retired by Anthropic

Anthropic retired Claude Sonnet 4 (claude-sonnet-4-20250514) from the Claude API on June 15, 2026, following its deprecation announcement on April 14, 2026. The model is no longer available in the EKB model selector. Anthropic recommends migrating to Claude Sonnet 4.6 (claude-sonnet-4-6); update any agents, workflows, or Smart Table columns that still reference Sonnet 4. See Anthropic’s model deprecations notice for details.

Default Model Change — GPT-5.4 nano

Effective June 15, 2026, GPT-5.4 nano is the default system model in Enterprise Knowledge, replacing GPT-4.1 mini. The new default offers stronger reasoning, larger output capacity, improved tool usage, and lower cost per token for most workloads. No action is required unless you want to keep using GPT-4.1 mini. In that case, set the model explicitly in the agent’s General tab before June 15, 2026 — otherwise, agents and workflows using the system default will automatically switch to GPT-5.4 nano. See the Default Model Change notice for cost impact, opting-out steps, and configuration options.

​
System Functionalities Affected by the Default Model Change

Agents If an agent has no model explicitly selected in the model selection option, it will fall back to the system default model. If the default model is changed:
  • The agent’s behavior and output may differ from previous runs.
  • Response quality, tone, and accuracy could vary.
Recommendation: Ensure each agent has an explicitly selected model configured beforehand to maintain consistent results. Workflows (LLM nodes) If a workflow contains an LLM node with no model explicitly selected, it will also default to the system default model. If the default model is changed:
  • The LLM node’s output may produce different results.
  • Downstream nodes that depend on this output may be affected, potentially impacting the entire workflow outcome.
Recommendation: Review all LLM nodes across workflows and explicitly assign the appropriate model before the change is rolled out. Prompt Suggestion feature This feature always uses the system default model and cannot be configured to use a different model. After the model upgrade, the quality of prompt suggestions is expected to improve. Prompt Improvement feature This feature also relies exclusively on the system default model and cannot be configured to use a different model. After the model upgrade, the quality of prompt improvements is expected to improve. Email Creator node (Workflows) The Email Creator node uses the system default model to generate structured emails. The instructions provided to the LLM are highly standardized, so no major change in output has been observed during testing. This node cannot be configured to use a different model directly. Smart Table LLM columns Any Smart Table column whose response is generated by executing a cell or column relies on the system default model and will be impacted by this change. Overall, output quality is expected to improve post-upgrade. Workaround if you need to revert to the older model:
  1. Go to Agent Builder and create an agent configured with the older model.
  2. In your Smart Table, update the column to use the agent as the response driver (instead of the default LLM).
The column will now use your selected agent — and therefore the older model — to generate responses.
