Since this is an add-on for an application, it won't get a full front-page announcement as with normal applications. But, now that the server issues have been fixed, Diashapes has been released!
Description: Diashapes is a small tool to download and install additional shapes (often called symbols or objects) into Dia Portable. It installs alongside your existing Dia Portable installation.

And thanks to Bart.S for his work on this!
I'll inform the original author about the release. Maybe he wants to announce it on his site too
