      <title>ok - and what is new?</title>

      <itunes:summary>&lt;p&gt;it is a bit boring and time consuming to click through the links (my impression is: graphics improved ... what else?)&lt;/p&gt;</itunes:summary>

      <itunes:summary>&lt;p&gt;If you prefer summaries, you may find these useful:&lt;/p&gt;
&lt;p&gt;&lt;a href="http://www.scientific.de/download/Maple13_WhatsNew_Professional.pdf"&gt;www.scientific.de/download/Maple13_WhatsNew_Professional.pdf&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;I guess they will appear on maplesoft.com as well.&lt;/p&gt;</itunes:summary>

      <title>improved in Maple 13</title>
      <link>http://www.mapleprimes.com/posts/37445-Maple-13-And-MapleSim-2-Now-Available?ref=Feed:MaplePrimes:Maple 13 and MapleSim 2 now available!:Comments#comment66295</link>
      <itunes:summary>You can browse the help system online at http://www.maplesoft.com/support/help/
In particular, http://www.maplesoft.com/support/help/view.aspx?sid=25596

A few of my favorite improvements are:
- they tweaked the garbage collector, improving overall performance by ~12%
- improvements to solving linear systems and svd
- 3d plots display faster and look better
- graph isomorphism test

There are some more technical things some people will appreciate:
- improvements to PDEs and DAEs
- fast element-wise operations on matrices
- improvements to polynomial system solving (RegularChains)
- gcd with algebraic numbers is much faster
- you can read in files with $define and $include

And then there are some tantalizing hints about what the future might hold:
- task programming model for parallel algorithms (like Cilk)
- multiplying and dividing polynomials mod p is over 20x faster
- asymptotically fast (FFT) polynomial algorithms in RegularChains

Overall it's a good release.</itunes:summary>
