With the new Associative option on (the default), ARRAYRECT and
ARRAYPOLAR build the array the way the drawing format stores one: the
selected objects move into an anonymous source block, an anonymous
array block holds one ByBlock reference to it per item, an INSERT of
the array block takes their place, and an AcDbAssocAction with an
AcDbAssocArrayActionBody, its three dependencies, the BaseNormal /
Origin / basePoint parameters and the value parameters tie them
together in the model-space network. The array is then edited from
Properties like an array read from a file.
The option flips with AS and is remembered for the session; on a
rotated working plane the commands keep making plain copies. Saving
drops the action of an array whose reference was erased or exploded.
Checked: created arrays reopen as associative with their parameters
and items, and the ODA converter reads the saved DWG without errors.

An associative array is an AcDbAssocAction with an
AcDbAssocArrayActionBody, dependencies on the array INSERT, the block
holding the item references and the block holding the source objects,
and value parameters (Items, ItemSpacing, Rows, …). Selecting the array
INSERT now shows its counts and spacings in Properties; changing one
places the items again and rewrites the item references, the body's
item records and the parameter values together, in one undo step, so
the drawing stays associative when saved.
Rectangular arrays follow their RowProfile axis, AxesAngle and base
normal; polar arrays turn about the centre recovered from their first
item, Radius and StartAngle. Both match the stored items of the
associative arrays in the sample drawings (122 of 123 rectangular, all
polar items of the polar samples). Path arrays are shown read-only.
