Mathematica 11 is now out and ready to compute! Since the release of Version 10 two years ago, Mathematica has grown by leaps and bounds, with 500+ new functions. This version introduces both enhancements to computations across the board and completely new areas of functionality, continuing Mathematica’s growth as the state-of-the-art technical platform—and we are very excited to share these developments with the world. Some of the most notable features include:

**[3D Printing](http://www.wolfram.com/language/11/3d-printing/)**

 ![triceratops.png](https://global.discourse-cdn.com/wolfram/original/2X/6/650a726bd9edca995b870e8b35a4396789108edf.png)

- Print your 3D models to local printers or online printing services with [Printout3D](http://reference.wolfram.com/language/ref/Printout3D.html).
- Use [FindMeshDefects](http://reference.wolfram.com/language/ref/FindMeshDefects.html) and [RepairMesh](http://reference.wolfram.com/language/ref/RepairMesh.html) to fix your models before printing.
- Hollow your models out with [ShellRegion](http://reference.wolfram.com/language/ref/ShellRegion.html) to lower the printing cost.

**[Computational Audio](http://www.wolfram.com/language/11/computational-audio/)**

![audioplot.png](https://global.discourse-cdn.com/wolfram/original/3X/f/1/f171ad5e5da77a139351586554dc0879a0834006.png)

- Version 11 includes a brand-new [Audio](http://reference.wolfram.com/language/ref/Audio.html) object to represent audio created from importing or an array of data.
- Edit your audio with [AudioPad](http://reference.wolfram.com/language/ref/AudioPad.html), [AudioTrim](http://reference.wolfram.com/language/ref/AudioTrim.html), [AudioSplit](http://reference.wolfram.com/language/ref/AudioSplit.html), [AudioResample](http://reference.wolfram.com/language/ref/AudioResample.html), etc.
- Synthesize sounds using the new [AudioGenerator](http://reference.wolfram.com/language/ref/AudioGenerator.html) function.
- Apply filters, take [AudioMeasurements](http://reference.wolfram.com/language/ref/AudioMeasurements.html) and visualize your audio with [AudioPlot](http://reference.wolfram.com/language/ref/AudioPlot.html).

**[Neural Networks](http://www.wolfram.com/language/11/neural-networks/)**

 ![neuralnetworkdigits.png](https://global.discourse-cdn.com/wolfram/original/2X/a/a861e7b7267da7d0245859dcd0c40b3fb8679374.png)

- Define network topologies with [NetGraph](http://reference.wolfram.com/language/ref/NetGraph.html) or with a chain of layers with [NetChain](http://reference.wolfram.com/language/ref/NetChain.html).
- Train your neural nets with [NetTrain](http://reference.wolfram.com/language/ref/NetTrain.html).
- Train networks on either CPUs or NVIDIA GPUs.
- Are your training sets of images too large to hold in-memory? The neural network functions support out-of-core image datasets.

**[Improved Machine Learning](http://www.wolfram.com/language/11/improved-machine-learning/)**

![CumberbatchMachineLearning.png](https://global.discourse-cdn.com/wolfram/original/3X/8/1/811eb1831d39539166bb1b8b60f2b0c913dfc380.png)

- [ImageIdentify](http://reference.wolfram.com/language/ref/ImageIdentify.html) now recognizes over 10,000 objects.
- Extract features from images, text and other data types using [FeatureExtract](http://reference.wolfram.com/language/ref/FeatureExtract.html).
- [Classify](http://reference.wolfram.com/language/ref/Classify.html) works even better with images, including an option to customize what [FeatureExtractor](http://reference.wolfram.com/language/ref/FeatureExtractor.html) it uses.
- Find formulas for time series data using [FindFormula](http://reference.wolfram.com/language/ref/FindFormula.html).
- Find clusters in your data with enhanced options for [FindClusters](http://reference.wolfram.com/language/ref/FindClusters.html), including new methods and setting a [CriterionFunction](http://reference.wolfram.com/language/ref/CriterionFunction.html).

And these are only just a sample of the new features, including the [Wolfram Channel Framework](http://reference.wolfram.com/language/guide/Channel-BasedCommunication.html), enhanced notebook processing, cloud-aware [WolframScript](http://reference.wolfram.com/language/ref/program/wolframscript.html), improved [symbolic and numeric calculus](http://www.wolfram.com/language/11/symbolic-and-numeric-calculus/) and so much more.

To read more about what’s new in Mathematica 11, read Stephen Wolfram’s [release-day blog post](http://blog.wolfram.com/2016/08/08/today-we-launch-version-11/) and check out the [New in 11 page](http://www.wolfram.com/mathematica/new-in-11/).

**Examples** in which the **MMA 11.0** gives **incorrect** or **strange** solutions.

Example1:

```
Sum[Floor[5/5^k], {k, 1, \[Infinity]}](* It should be 1 *)

```

Example2:

```
eq = y[n] - 1 - 1*Sqrt[y[n]] - y[n + 1];
sol = First@RSolve[{eq == 0, y[0] == 1}, y[n], n];
Table[(y[n] /. sol), {n, 10}] // N
RecurrenceTable[{eq == 0, y[0] == 1}, y, 
    {n, 10}] // N(*Answers not the same *)

```

Example3:

```
eqn5 = (y'[x])^2 + y'[x]*y[x] - x == 0;
DSolve[{eqn5}, y[x], x](* strange results *)

```

Example4:

```
 FourierTransform[Exp[a*t]/t, t, \[Omega]](*incorrect answer *)

```

Example5:

```
InverseLaplaceTransform[Coth[s], s, t]
InverseLaplaceTransform[Tanh[s], s, t]
InverseLaplaceTransform[Sech[s], s, t]
InverseLaplaceTransform[Csch[s], s, t]
(* strange results *)

```

Example6:

```
 Integrate[Sqrt[Exp[I*t]^2 - 1], {t, 0, Pi}](*incorrect answer *)

```

Example7:

```
 << Quaternions`
 Exp[Quaternion[1, 0, 0, 0]]
 (*bug or errors*)

```

Example8:

```
 Integrate[Sin[q]^2/Sinh[q]^2, {q, 0, \[Infinity]}](*incorrect answer *)

```

Example 1:

But

```
In[1]:= Sum[Floor[5/5^k], {k, 0, \[Infinity]}]

Out[1]= 6

In[2]:= Sum[Floor[5/5^k + 10^-1000000], {k, 1, \[Infinity]}]

```

The bug is because of Sum[] function:

```
In[3]:= Table[Floor[5/5^k], {k, 1, 10}]

Out[3]= {1, 0, 0, 0, 0, 0, 0, 0, 0, 0}

Are you a ‘prerelease’-tester (beta-tester)? If not, perhaps you can sign up; send them an email [prerelease@wolfram.com](mailto:prerelease@wolfram.com) I’d bet they would have liked to know about this before release. They intend to resume the prerelease program for version 11.1

No I’m not a Beta tester. A lot of Bugs can be found on this [Website](http://mathematica.stackexchange.com/questions/tagged/bugs?sort=newest&pageSize=15),only need to **test** (for **Bugs** ) them for MMA 11.0.

Advice to pre-release testers. In order to use the activation code for version 11 from the user portal, you’ll need to delete the pre-release versions from your license file. If you don’t, the activation code will not be asked for and your license will remain as the pre-release license.

These are not regressions. They were known before, as I remember several of these examples from StackExchange. I think what Mariusz meant was that even though these were known problems, they were still not fixed in version 11.

To be fair, I should note that my _subjective_ impression was that symbolic math related bugs like these got fixed with higher frequency than other problems. This is based on going through a few random `bugs`-tagged questions on StackExchange and seeing which got fixed.

Or –  
You just use the menu item and enter the new activation code. You can delete the old one if you like, but it is not necessary.

You can check to see if the activation is yours or the pre-release by looking at About Wolfram Mathematica. If the Registered name is your name, then you have successfully entered your activation code. If it is (still) Arnoud Buzing (sp??), you need to enter your activation key using the Help/Enter Activation Key… menu item. You get the key itself from your user portal.

If you ever look at the file that contains the activation keys (use a text editor), it can have lots of keys. Mathematica uses the first on in the list that ‘works’.

Hi,

Before even trying the recent version 11, I would need to know whether the following bugs have been fixed :

1. **Graphs with multiple edges and problems with edges layouts and colouring**

In fact, this is a direct question to Szabolcs Horvat, since he knows well the multiple edges issue and, I guess, can give a definitive answer.

> [@Graphs with multiple edges and problems with edges layouts and colouring](https://wolfram.discourse.group/t/7086/1):
>
> In trying to plot a graph, I came across a serious inconvenience with styling and plotting edges which seems a bit odd and pretty unexpected. The documentation (Help) says, and we knew, that the last style specification overrides the previous. But there is nothing in the Help about the fact that multiple edges between two vertices are considering to be unique (just one edge, just the same) for some purposes and not for others. As the issue is hard to explain in plain text, I have attached on…

1. **Problems with ‘Hyperlink[“label”,(“notebook.nb”’,“celltag”}]**

> [@Problems with 'Hyperlink\["label",("notebook.nb"',"celltag"}\]](https://wolfram.discourse.group/t/8364/1):
>
> Hi, I am facing the following problem (\* The following sometimes works but sometimes does not \*) (\* The issue has been tested in many occasions and situations \*) (\* The format does not even launch the linked notebook \*) Hyperlink["label", {"notebook.nb", "celltag"}] (\* However the following always work \*) Hyperlink["label", "notebook.nb"] (\* Both formats have been tested many times in the same situations and conditions \*) Any help will be wellcome. Martin.

Thank you

Martin.

No!

None of them has been solved in Version 11.

Another two bugs left behind.
