You can now use any version as the Switchover source of another, so a forecast can build on another forecast, a budget can roll into the next, and more.

✨ What's new

Switchover source now works across every version type. A budget can inherit from a forecast, a forecast from another forecast, a budget from another budget, or a forecast from a budget. Whatever planning structure you need, you can point one version at another so it carries the source data up to the switchover date and continues with its own data after it.

⚙️ How it works

Open the version you want to configure and click Edit. In the Switchover section, select another version under the Version field. The list includes both your forecasts and budgets. Save, and your version references the selected source up to the switchover date.

Numbers and model structure change, and it isn't always clear why. A formula was edited, a variable's setting changed, a model was renamed or restructured. The Activity ledger now tells you who did it, when, and what the value was before.

✨ What's new

• The Activity ledger, which already tracked your versions, scenarios and manual inputs, now records every structural and content change to your models and variables, with the person who made it and, for most edits, the value before and after.
• On the model side, it captures creating, duplicating, renaming, moving and deleting a model, creating, renaming and deleting the sections that organize your models, and every change to the switchover date, including the automatic moves that happen when new actuals sync in.
• On the variable side, it captures creating, duplicating, renaming and deleting variables, formula edits per version, actuals formula changes, calculation strategy, input type, aggregation, dimensions, style, description, and importing a global variable from another model. Formula changes made at the sub-dimension level are recorded too: open View changes on the event to see the previous and new formula for each dimension item.
• You can also just ask. Tell the AI Agent "What changed in this model last week?" or "What did Ana change in Revenue since July 1?" and it answers from the same ledger, with the same permissions, grouping everything saved together as one change.
• Deleted models and variables keep their full history, so you can always trace back what happened to them.

⚙️ How it works

Open More (…) → Activity from the left sidebar. Each row is a single change, sorted from most to least recent, with the event, its details, the affected resource and the user who made it. The ledger is permissioned by access, so you only see events for the models you have access to.

The ledger starts recording from the moment the feature is enabled for your organization, so earlier changes are not captured.

🔜 Coming soon

• Access from the public API.
• Filters and download on the Activity page.
• A richer visual format for the Agent's activity answers.

We got feedback that the old full-model view was too cluttered to read or present. We are moving away from the old diagram, and you can really understand what drives any number. The Model Map opens focused on a single variable and shows exactly what feeds it and what it feeds, so you can trace the logic behind an output, spot where a number comes from, and explain your model to anyone.

✨ What's new

• A new Builder / Map switch lives at the top of every model. There are two ways in: click "Show variable in diagram" on any variable to jump straight to it, or open the Map tab and pick a variable from the structure panel. Either way, the Map centers on that variable and lays its dependencies out left to right, precedents on one side, dependents on the other.
• A depth controller lets you set how many dependency levels to reveal upstream and downstream, independently, so you can follow a chain as deep as you need, from Units Sold to Net Income.
• A left-side structure panel mirrors your sections, groups and variables so you can find anything in context, even variables tucked inside groups. Two more tabs list the external models connected to this one and the datasets feeding it.
• Nodes now show each variable's location, logic type and dimensions; datasets appear as source nodes with their integration and last sync; and cross-model references render as external variables colored differently, so data lineage is clear end to end.
• You can also read the logic behind every variable. Each node shows how it's calculated, whether that's a formula, a manual input, a moving average, an AI forecast or same-as-actuals. And for mixed-logic variables, where the calculation differs by dimension, you can now see the logic broken down per dimension, so even the most complex parts of a model are readable at a glance.

• Right-click any node for its options:

  • "Filter by this variable" makes it the new focus of the Map, so you can pivot from one variable to the next to progressively investigate upstream or downstream dependencies.
  • "View in model builder" takes you back to the Builder with that variable selected. Selecting a node opens its info panel with description, configuration and dependencies, read-only.
• Trace a path between two variables: click one, then another, and the Map marks the route connecting them.

Building your Actuals formulas just got more flexible. The constant values you already use in Versions now work in Actuals too.

✨ What's new

You can now type a constant value directly as an Actuals formula. Enter a fixed value like 2000 to apply it across every period, use a conditional such as IF CurrentMonth IS Jan THEN 1 ELSE 0 to flag specific months, or use operators like MonthNumber and YearNumber on their own. It's the same syntax you already know from Versions, now available on the Actuals side. This makes it easy to express flags, multipliers, thresholds, and manual overrides directly in your historical data, keeping the logic inside Abacum instead of in external spreadsheets.

⚙️ How it works

Open the formula editor on the Actuals side of a variable and type the value or expression. The constant applies across the variable's actuals period. For variables with dimensions, the value is applied at the unallocated dimension item.

Reorganizing a model just got significantly faster. You can now move multiple variables to a different section in a single action, without having to reposition them one by one.

✨ What's new

When working in the model builder, selecting one or more variables now shows a "Move to" option in the bulk action bar, alongside the existing Delete, Duplicate and Show empty values actions. Clicking it opens a section picker, and all selected variables land at the bottom of the target section, preserving their formula references and values.

Group behavior is handled intelligently. If all variables in a group are selected, the entire group moves together as a unit. If only some variables in a group are selected, those variables are extracted individually and moved, while the rest of the group stays in place.

⚙️ How it works

Select the variables you want to move, click "Move to" in the action bar, and pick the destination section. Abacum automatically scrolls to bring the moved variables into view, keeping the section header and the newly placed variables centered in the viewport.
