It's mentioned in the PARAMETERS section:

       uated.   When += is applied to an array variable using compound assign‐
       ment (see Arrays below), the variable's value is not unset  (as  it  is
       when  using  =),  and new values are appended to the array beginning at
       one greater than the array's maximum  index  (for  indexed  arrays)  or
       added  as additional key-value pairs in an associative array.  When ap‐
       plied to a string-valued variable, value is expanded  and  appended  to
       the variable's value.

It's not mentioned under Arrays, though.  Might not hurt to repeat it.
