Unfortunately at the moment there isnât a way to tell what is new. The best indicator of newness or updates is actually the activity here on the forum.
The package/script/project manager isnât terribly sophisticated. All maiden knows is that there are one or more catalog files that it can download which list the available scripts (one file per section on the available page). One thing which is definitely not captured right now is when (in calendar time) a script was added to the catalog - the absence of that information is the biggest reason why maiden canât provide a view into what is new.
Knowing when there are script updates has similar challenges. A conscious decision was made back when the project manager was built to avoid requiring all the scripts be stored in a specific place and to avoid requiring authors to version their works. The idea was to allow script authors to share via any service/host they were comfortable with as long as the files were publicly downloadable. One consequence of that choice was that maiden doesnât have much visibility into when things change. In practice I periodically hit the update all button (or one of the script specific update buttons) on the installed page.
I wouldnât worry about that. Suggestions and feature requests are always welcome, they help to shape how parts of the system evolve and can serve as inspiration for people who want to get more deeply involved.
