False malware detection
Now, I have minified render.js again, but a portion of the code is minified with only Shrink Variables method, and for this new render.min.js, Sucuri is no longer reporting malware. This new file is now included in the GD bbPress Toolbox Pro 3.8.3. This points to a problem with Sucuri scanner and I have contacted Sucuri Labs to resolve the issue and determine why their scanner returns false malware report for this file, and only when minified. I will let you know how that goes. Right now important thing to know is that the plugin is safe, containing no malware. To avoid malware reports from Sucuri, new plugin version contains differently minified file.
And, if you find any other issues with this or any of Dev4Press other plugins, please let me know as soon as possible.
Edit on September 11 2015:
Sucuri has responded to the false positive report, and adjusted their detection engine to this detection error, and from now on it should not report false positive malware for this plugin.
Development of version 4.0 is well underway now, and list of planned features is expanded further to include few new ideas. You can check out this post to learn more on what to expect in 4.0.
