Critically, this will make user, site and server admin uploaded apps live. That will mean that the core engine and features can progress independently. And people can write new features without having to bother with PHP or the build system. Apparently that means "quick search feature for tentacle hentai", according to one person. Luckily, while you can share apps, you can't force them on anybody (unless you're the site or server admin).
Possibly included, depending on ThePaidWorkLoad:
- Rejiggering the build system so that XDebug works again.
- Basic documentation for the various exposed data you can call out (see also JS apps).
- Basic documentation, period
- Drop 5.2 compatibility. (If not now, very soon)
- A new slick signup and login system.
