Serena Capabilities 🤖​

We have improved Serena's agent creation capabilities. You can now add files directly during the conversation, and Serena will use them as context and knowledge for your agents. Serena can also identify the agent's objective and suggest the necessary skills when needed.

Shared Subtenancy 🤝​

The new shared subtenancy feature makes it easier to create agents that can be shared across your organization without manual subtenant assignment. You can now define whether an agent or entity is restricted to the root level, assigned to a specific subtenant, or shared with everyone.

Enhancements ✨​

Groups 👥​

Group details now provide a clearer view of how each group is structured. You can easily see which users belong to a group and whether they come from a subtenant or were added manually.
