Hello xShellzers,
we were working on this 2.0 release about 6 months.

Complete xShellz code base has been rewritten into modular components.

Short technical background:
We're using PHP as a backend for xShellz website and Python for MQTT (shell operations). IPC is custom written and communicates between PHP and Python.
For a frontend, we're using jQuery, Angular 1.*, and as usual gulp/npm/bower for automation build.
Custom CI tool has been developed, which reports to xShellz Staff at IRC.

So, what's new?

No more !info !approve on #xShellz IRC. #xShellz is now support only. (!keep is still allowed on both irc and web)
Manage your shell via xPanel.
Xinfo has its own page now https://www.xshellz.com/xinfo

Shell operations are now 10 times faster than before.

You can also track irc channel in realtime here https://www.xshellz.com/irc/realtime/xshellz

We're now using OAuth2.
API docs and demo/try are available here https://www.xshellz.com/docs and here https://www.xshellz.com/api/try

Webhooks for your shell operations has been implemented as well (check docs).
