It is really a little thing.

First, matrix display in Big Language mode:

  Before, entries to the matrix were actually printed in Flat Language

  Now, they are printed in Big Language, with vertical boxes expanded to the
size of the highest expression in a row

Second, `apart' bug fix:

  Before, inside `math-partial-fractions', `math-padded-polynomial'
calculated the polynomial representation of the remainder using
`math-is-polynomial' and not taking into consideration, that the last one
might return nil

  After, I inlined `math-padded-polynomial' to compute `math-is-polynomial'
and in case the latter returns nil, report an error "Expected a rational
function".

Best wishes,
Lukasz
