- The `eps`, `flintmax`, `intmax`, `intmin`, `realmax` and `realmin` functions now accept the `"like"` syntax to return scalars based on a prototype object
-`qr` and `gsvd` have a new `"econ"` option for economy-size decompositions
- The syntax `R = qr(A)` now always returns `R` as an upper-triangular matrix, regardless of whether `A` is full or sparse (behaviour change)
