Built-in Extensions Manager tool allows to get access to hundreds official and third-party resources of the following types: usage examples, plug-ins, SMath Viewer based applications, snippets, interface translations, interactive books, handbooks and tutorials.

Changes introduced in current build

Improvements

  • The following functions are now support units: round(...) and trunc(...);
  • SS-2284: Support for +-infinity as an argument implemented for sinh, cosh, tanh and coth;
  • SS-53, SS-2261: The following quantity units implemented: %, ‰, ppm and ppb;
  • Calculation performance improved;
  • Languages updated;
  • Refactoring.

Corrections

  • SS-2292: Symbolic calculation error of augment(...) and submatrix(...) functions fixed (happened sometimes when matrices in arguments were negative);

Hi Andrey,

Thank you for this new release, with very welcome changes.
When I look at Help->About window, I see "Date: 17/09/2015". A time machine to the past? ;-)

Yes, it is my fault. Forgot to update a date. Sorry for this.
But it will be the last time this issue happened as I just added date updating to the automatic deployment procedure.

Best regards.

Thanks for reminding - calculation speed was really a bit improved. Added this to change log.

Please let me know if you find a reason. To say truth I expected nothing should be changed in worksheets or plug-ins for this release.
At least hundreds of my complex test worksheets was opened and calculated without any errors before releasing.

Best regards.

That's what I'm afraid: scrapping so many work sheets.
Guess what: it would scrap my most precious ones.
Is the solution, purchase or rent a new PC for each new release ?
Not bad an idea as beta testing ... my laptop is too small to avail.

Now, the savant question(s):

I presume that each new release does not evaporate the previous one.
If things go bad, will XP restore the previous version ???
My question is pertinent because Smath is absent of the Windows Registry.
It looks to work by itself and might got lost by itself as well and what
about my 250 work sheets ? Murphy's law might apply.

Please don't think that one day soon SMath will gone or will be changed dramatically, so you will not be able to work with your old worksheets. This scenario is not realistic at all.

1) I realize that I have no right to forgot about back compatibility.
2) Before every release (and also during development) I always execute automatic tests to ensure nothing broken in the logic implemented earlier - I have a bundle of about 800 different worksheets. SMath Studio opens them, recalculates and compares results with previous ones. Any registered deviation is my priority task.
3) I've created a tool (with a great help from developers from our community Thank you ) which allows me to support third-party plug-ins even if authors will not be able to do it anymore. So I can give a guarantee that most of all plug-ins available via Extensions Manager will work for future SMath Studio releases.
4) All previously released versions are still available for downloading, so one can test them if it is really required.
5) I'm not the one who have access to all sources of SMath project (including SMath Core, web-sites and different related tools), so even if something bad happened to me project will continue living and growing.

Yes, sometimes I have to do significant changes to API, but I always try to inform about it all the developers and users (I remember only one such situation when logic on the worksheets was changed, so it required small changes to some documents) and publish nightly builds to provide some time for plug-ins migration. This is life. But it is important that all these situations was successfully passed.

Best regards.

Yes, please. I will test your file and plug-in and will find a reason.

Done. Will be available in the next SS version.

Issue investigated and the reason is found. It is because DISLIN plug-in overrides line(4) function (line with two rows).
I will contact uni Offline regarding it. For now I suggest to just uninstall this plug-in.

More details sent to your e-mail.

Thank you and best regards.
