Version 5.3.7 (CS) - October 16th, 2026

Weissr has a new look. Version 5.3.7 brings the new logo, font and brand colours to every module.
In Capex Strategy, the new process rail shows where each alternative sits in the strategy process, and External Data cells can link to the Base Alternative. The AI chat is now called Weissr Assistant and works in Capex Strategy too. The release also includes performance improvements and bug fixes for issues from earlier versions.

A new look for Weissr

Weissr launched its new brand on 8 October 2026, and the product now matches the website. The logo, the font, the navigation and the main colours are new. Layouts, icons and chart colours stay as they are, so every screen works the way you know it.

📍 What's new

• New logo and favicon: The new Weissr logo is shown in the navigation, on the login page, on the application selection page, and on the error, email approval and exchange rates pages. The browser tab shows the new favicon.

• New font: Text across the product uses the font from the new Weissr brand.

• New navigation and colours: The navigation bar, buttons, links and selected rows use the colours of the new Weissr brand. Text links in running text and grid cells are underlined, so you can tell them apart from body text.

• Administration in the new brand: Administration uses the same colours as Capex Management and Capex Strategy.

• PDF exports: Standard Capex Management PDF exports show the new logo in the footer. If your company has uploaded its own logo, the footer keeps showing it.

• Weissr Light by default: When no theme is saved in the browser, you see the Weissr theme in Light, even if your computer is set to dark. If you already picked Classic or Dark, your choice is kept.

• Theme hint: The first time you open Capex Management or Capex Strategy after the upgrade, a hint at your initials explains the new look. It shows once per user.

📌 Note: Decision PDFs saved before the upgrade keep the old logo. The theme is saved per browser, so a user who picked Classic sees Weissr Light again in a new browser.

Theme and appearance

To change the look, click your initials in the navigation bar. Under Theme, choose Weissr or Classic. Under Appearance, choose Light, Dark or Auto. Auto follows your computer's setting.

Coming in later versions

This is the first step in bringing the new Weissr brand into the product. More of the interface will follow over the next versions, a few areas at a time, so each change is small and easy to get used to. How you work and your data stay the same.

💡 Info: Classic, the look from before, stays available from the user menu while these changes roll out, and keeps the previous font. It will be removed in a later version.

Weissr Assistant

The AI chat is now called Weissr Assistant, and it works in Capex Strategy as well as Capex Management. Open it from Help > Weissr Assistant.

📍 What's new

• One name everywhere: The help menu, the chat window and the assistant itself say Weissr Assistant, where they used to say Weissr Capex Chat or Virtual Assistant.

• Alternatives in Capex Strategy: Ask for property values of one or more alternatives by name or by type. Alternative names in the answer are links. Private and confidential alternatives are only shown to users who can see them, and deactivated alternatives only when you ask for them. If a name matches more than one alternative, the assistant asks which one you mean.

• Welcome message: The assistant lists what it can help with in your environment, such as finding and filtering requests, showing property values, creating a request and answering questions about how Weissr works. Ask "What can you do?" at any time to see the list again.

📌 Note: In Capex Strategy the assistant reads data only. It does not change alternatives, and it does not cover cash flow rows or asset data yet.

🔧 Configuration: Each capability is switched on per environment. A capability that is switched off is not listed.

Weissr Capex Strategy

Capex strategy process rail

The alternative form now shows where the alternative sits in the Capex strategy process. A read-only rail above the Summary and Form tabs shows the four stages: Where we are, What we can do, How good we can become, and Recommendation for action.

📍 What's new

• Stage by alternative type: Base Alternatives and Division Base Alternatives are in stage 1, Strategic Building Blocks in stage 2 and Strategic Alternatives in stage 3.

• Final stage for the current strategy: Stage 4 is reached when the alternative is approved as the current strategy.

• Position text: The rail tells you where you are, for example Stage 2 of 4.

Link to Base Alternative in External Data

The Link to Base Alternative action you know from the cash flow grid is now available in the External Data grid of Strategic Building Blocks and Strategic Alternatives. Linked cells follow later changes in the Base Alternative, so you no longer need to copy values by hand.

• The action uses the same menu and rules as in the cash flow grid.

• Export, cell log, reset and delete work the same way as for existing links.

🔒 You need permission to update External Data, and the project must be unlocked. The action is not offered in the Base Alternative itself.

Base Alternative row function in the model builder

A new row function in the model builder returns the value of a row as it is calculated in the Base Alternative. Use it when an alternative should always compare against, or build on, the Base Alternative figures. In the model builder you write it as BASE(row_reference).

• The function works in Capex Strategy models. Capex Management models reject it when you save.

• If the row or node does not exist in the Base Alternative, the function returns 0.

• Sensitivities of the current alternative do not apply to the Base Alternative value.

• A manual input in the cell overrides the function.

• You can also type the function directly in a cash flow cell of a Strategic Building Block or Strategic Alternative. There you use ALT(row_reference; "alternative_short_name") with the short name of the Base Alternative, for example =ALT(M22; "b").

Copy and paste in the cash flow sheet and model builder

Copy and paste in the cash flow sheet and the model builder now behaves like Excel, including pasting a range vertically.

Performance

These changes make Weissr more responsive when many people work at the same time and right after a restart.

• Many users at once: The server no longer freezes when around ten users work in the system at the same time.

• After a restart on MS SQL: The first requests after a deploy or restart are no longer blocked for one to two minutes by database index maintenance.

Bug fixes

These fixes correct problems that were present in versions before 5.3.7.

Capex Strategy

• Deleting a large division: Deleting a division with many Strategic Building Blocks and Strategic Alternatives, for example 200 of each, no longer fails with an error. Present since 3.13.

• Projects that stopped responding: Two locking problems could make a Capex Strategy project stop responding for everyone working in it. One happened when calculations ran at the same time, the other when a division was created on MS SQL.

• Duplicating an asset: Duplicating an asset did not copy its reinvestment updates. Present since 5.2.3.

• Sites shown as changed: A site created in the Base Alternative could be shown as changed in a Strategic Alternative after several cash flow cell changes and switching between Strategic Alternatives. Present since 5.3.

• Site comparison chart: A site created in a Strategic Alternative was not shown in the chart when you selected it in the site comparison of a site report. Present since 5.3.

• Edit formula mode: In the cash flow, a Machines block cell used in a formula was not highlighted in edit formula mode after the cell was reset. Present since 5.3.

• Percentage cells: Entering a digit in a percentage cell with an expression in a model sheet multiplied the value by 100. Present since 5.3.3.

• Comma as decimal separator: A comma decimal separator was read as a thousand separator when you pasted or entered a value in a numeric cell. Present since 5.3.5.

• Asset ledger year validation: The validation message said a year could be equal, but equal years were rejected. Present since 5.3.5.

• Moving an asset in the asset ledger: Dragging an asset onto another category reordered it within its own category instead of moving it.

• Asset history in Logs: After a server restart, Logs > Assets could show the history of a deleted asset for a new asset. Present since 5.3.5.

All applications

• Today's date in Weissr Assistant: When you asked the assistant for today's date after it had looked up data, it could answer with a date taken from the documentation. It now gives the correct date. Present since 5.3.1.

Administration

• Insert tags in Capex Strategy notifications: The insert tags menu closed as soon as it opened, so you could not pick a tag. Present since 5.3.5.

• Expression field in Properties: In Admin > CM > Properties, the expression field did not grow to fit the expression when you opened a property. Present since 5.3.5.

• Context menu in Properties: The context menu in Admin > CM > Properties did not close when you clicked outside it. Present since 5.3.5.

• Password strength: The set new password page did not rate a password as Weak when it was shorter than 8 characters or repeated a character three times in a row. Present since 3.4.

User provisioning

• Status of user group synchronization: The integration log no longer shows a successful status when user group synchronization for external users has failed. Present since 5.3.1.

• Skipped users in the integration log: When a disabled user is skipped during user group synchronization and not linked to a group, the integration log now counts that user as skipped instead of showing 0. Present since 5.3.1.
