In Settings → Admin → Data, Axi used to stop and ask before doing what you had just asked for. It now puts the change in your draft straight away and tells you what it assumed — the draft is where you review it, and nothing is saved until you press Save model.
Axi answered about the table you had open, because that was the only thing it could be told about. A picker above the message box now says what it is looking at — This table, or Whole connection — and a sweep no longer needs you to type "continue".
Axi could describe your tables and declare their keys. It can now write the two things you actually build dashboards on — measures with their business rule baked in, and metrics — and it checks a metric against the engine before offering it to you.
Axi could describe the table in front of you. It can now work through the whole connection — and the left rail saves the result in one press.
Axi could already put a key in your draft. It now reads your data first, and shows you the count it read.
Axi could already explain your semantic model. It can now change it — by putting the change in your draft, where your own edits live, and leaving Save model to you.
The Check card on a metric's page told you the definition compiles. It now also tells you the number: Run executes the metric — unsaved edits included — and shows its value over the last 30 days.
On a BigQuery connection, the table page in Settings → Admin → Data now shows nested fields as rows of their own and keeps flatten models next to the table they come from.
Selecting a column on a table page now opens an inspector beside the list, where the column's dimension is edited in place — no more switching to the Dimensions tab to rename a field or tag it as mappable.
The connection form is no longer a dialog. Each connection's Settings is a page in three sections, and the Data rail now tells you at a glance how big each connection is and whether it works.
