API Reference Sections Renamed: Change Tracking & Employee Tables

We updated two category names in the API reference and moved one endpoint between them:

• "Last Change Information" is now "Change Tracking."
• "Tabular Data" is now "Employee Tables."
• Get Changed Employee Table Data (GET /employees/changed/tables/{table}) moved from Employee Tables into Change Tracking, so the two "what changed since" endpoints now sit together.

This is a category change only. None of the actual endpoints are affected.
