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.
