As always, thank you for your hard work.
I'm looking forward to the latest changes.

I just updated to this version and I had the following plugins fail to load:
-Checkbox Region
-Combobox Region
-Conditionally Formatted Label
-Data Exchange
-Modeller Region
-XLSX Import/Export
-Script Region
-all of my custom plug-ins

I was able to resolve these errors immediately for everything except:
-Script Region
-all of my custom plug-ins

The 'error' that was being flagged for all of these plugins were:
A strongly-named assembly is required. (Exception from HRESULT: 0x80131044)



Just so people have a 'heads up'

I suppose it depends on the previous version of your SMath Studio (I've not noticed issues updating from the latest Nighlty Build). Simply uninstall them and download the most recent from the extensions Manager. If you still have issues let me know and I'll update the broken plugins.

It is because the plugins are compiled using not compatible APIs. Recompile your plugins using the new SMath Studio libraries.

Your custom plug-ins must be recompiled in order to support this version of SMath Studio.
As I see Script Region is a third-party plug-in with closed sources. If its sources will be published to https://smath.info/svn/public/plugins/ - then it will be possible to support new versions of the program automatically. But for now you should ask developers to recompile it directly.

Best regards, Andrey Ivashov.

Glad to hear! Many thanks for your support!

About Script Region. I didn't have time to publish the source code. Now I need find it and publish.

As always, thank you Andrey. I really appreciate your efforts.

I see a cloud version (link) ... what happened to the portable version? Are there any plans to do a portable version again? That's what I like to use!

Excellent!

I like this software. Are you going to update the Pocket PC version for more features?

Thank you for the update and all the hard work! I also still use Windows Mobile and would highly appreciate an update for it.

Back in Aug of 2014 I had downloaded a package SMath and Maxima. It just runs from the folder without having to install. It's very convenient and I take it with me everywhere. I would like to update to the newest version. Is there anyway I can keep it in this same easy to carry package?

It appears that you have the latest version. MKraska is the current keeper of the unofficial portable version (I am still hoping for an official one again)
https://smath.com/wiki/SMath%20with%20Plugins.ashx still shows 11/16/2014 as being the latest.
