A new version of VStar is now available. To get it, simply download it from this page: http://www.aavso.org/vstar-overview [1]. If you already have the vstar.jnlp file saved on your computer, you will get the new version of VStar automatically the next time you use it.
Since changes were also made to many of the plugins, you should delete any you might have from your vstar_plugins folder and download again the ones you want from here: http://www.aavso.org/vstar-plugin-library [2]. Alternatively, you can download a file called vstar_plugins.zip from the same page which contains all of them.
Here is a summary of the major changes and bug fixes in this version:
Thank you, David!
