Malware Protection
Explore, like most programming languages, has many useful features that can also be used to create viruses. There will be a malware protection feature in Explore 4.
Windows Installer
During development of Explore 3.3, jueschnei began working with powerpoint56, and created a new Windows Installer that is still in active development.
The installed version of Explore by jueschnei comes with many helpful new features. It automatically keeps Explore up to date, and has its own Explore2EXE converter. Recent development has been focused on the Explore Store, which will let users share and browse projects, plugins and more.
Future Development
Powerpoint56 and jueschnei are working on the Explore store and Explore 4. Jueschnei also is working on the Windows installer, the Explore store, the updater, the website, and other improvements to the Windows installed version.
