Most of the integer + arithmetic operations was rewritten to exploit integer arithmetic in the CPU + efficiently. As a result, performance was significantly improved. + + ** Diagonal and permutation matrices + The interpreter can now treat diagonal and permutation matrices as special + objects, rather than general full matrices. Therefore, it is now possible + to construct & use these matrices in linear algebra without suffering a + performance penalty. + + See NEWS.3 for old news.
