Features

• Custom factors now group on rules across your columns. Each group is a rule that can reference any column in the dataset, and you can drag the groups into the order you want them applied. As you author, every group shows how much of your data it actually covers, and a catch-all collects whatever falls through.
• The data grid shows the whole dataset. Every row and every column is reachable, with cells arriving as you scroll and any row in the dataset one jump away.
• Correlations can be weighted by a target's exposure, chosen from a dropdown above the correlation view.
• Geographic hierarchies now offer what a column page does: a map recolored by an enabled target, a table of the underlying numbers at each level, and the usual export and fullscreen controls.

Improvements

• A level with no exposure stops holding up a fit. When a factor group matches none of the rows you're fitting on, it's left out of the model and its rows score at the base level. Only an empty base level still blocks the fit, and that message tells you which one.
• Legend entries carry definitions on hover, and right-clicking a legend entry, filter badge, or partition opens its menu.
• Expressions accept datetime literals and full 64-bit integers.
• Large datasets read and render faster throughout the app.
• Permission changes in cloud organizations apply with far less overhead behind the scenes.

Fixes

• Replacing a dataset's file updates its properties and distribution charts everywhere they appear.
• View pages and legend tooltips show column names rather than raw identifiers, and long values in a tooltip wrap onto a second line.
• The Data page's column picker reports each column's real type.
• Chart exports name every column by its measure, so bar and line series stay distinguishable in CSV and TSV.
• "View as map" appears as soon as you associate a geography with a column, with no restart.
• A GeoJSON file containing no features imports as an empty geography.
• AI agents can set filters and partitions again through the local MCP server, and installing that server works on macOS 26.
• macOS window controls hold their position between onboarding and the main app.
• Branching in the middle of an edit leaves you on the new branch.
