This update makes warehouse configuration clearer by offering three setup levels, from a single warehouse and location to multiple warehouses with multiple locations. It also adjusts related menus and fields so users only see options relevant to their chosen warehouse complexity, and ensures new companies get a related warehouse automatically.

Source documents shown in the chatter history can now be opened directly, making it easier for users to trace conversations back to related business records. This improves navigation across sales, purchases, stock, manufacturing, and events when reviewing document history.
