Version 5.3.1 (CS) - June 29th 2026

5.3.1 is a release that strengthens how Weissr Capex handles financial data and gives administrators more control. Deleted requests can now be recovered, forecasts and actuals are tracked separately to support future reporting, and the Decisions tab is now mobile-friendly so you can review and act on requests on the go. The release also includes minor bugfixes

Weissr Capex Strategy

Smoother series visibility in charts

Toggling series on and off during a presentation used to show a loading indicator on every single click, which broke the flow when switching between lines rapidly. Visibility changes are now applied immediately in the UI and saved in the background with a short delay, so the experience stays smooth throughout.

📌 A brief loading indicator still appears on the first toggle of a newly created chart that has not yet been saved. This is expected.

Connect Weissr Capex to AI assistants (MCP)

Weissr Capex can now be connected to AI assistants that support the Model Context Protocol (MCP). Once connected, the assistant can discover and use Weissr Capex tools to work with your data on your behalf.

This feature must be explicitly enabled by Weissr before it can be used. Contact Weissr to have MCP connectivity activated for your environment.

📍 What's new

Secure sign-in: Connecting uses the OAuth 2.0 authorization code flow with PKCE. You sign in on the Weissr side, and the assistant receives a token that represents your session, rather than handling your credentials directly.
Permission-aware access: The Weissr Capex MCP server is available as a remote HTTPS endpoint. Every request is validated and tied to your user session, so the assistant only ever sees the data your existing permissions allow.

📌 Current limitations: In this release, the connection supports retrieving data, and creating a request with the information required by Weissr Capex: request name, analysis start year, and production unit. Other fields are not editable through an AI assistant yet, and editing existing request data is not yet supported. Both are planned for a future release.

⚠️ Note: Responses are generated by the connected AI assistant, which processes your data to produce its answers. Results can contain errors, so always double-check them against Weissr Capex before relying on them for decisions.
