This is minimal change, but is quite annoying to don't have the routing settings on the same place. This get fixed in V4 and now SEO routing settings are under Dashboard > Settings > Routing.
This enables to register an auth device (Google authenticator, et all) to strengthen access to accounts by requiring a random key provided by the auth device.
With this, accounts will be more safer as even if an attacker manages to discover your password it won't be possible to access unless providing the 2FA code.
Expiration time is now visible on main upload form, same as category and album. With this you can now easily bulk set the expiration date for your current upload.
Calls to API V1.1 using the public key at Dashboard > API will now be handled as guest uploads, meaning that it follows all guest upload restrictions you may want to configure (enabled, guest max upload file size, etc).
Authorization in API V1.1 gets improved with support for header authorization. Instead of passing key in the body you will now be able to pass the X-API-Key header with the target API key.
The uploader has been improved for iOS devices (missing upload button, not rounded borders), also the fixed uploader now blocks the page scrolling in the background when opened.
Login now uses accent color for the submit button (arrow icon). Autofilled account details (username, password) now follow the palette color as it overrides the browser defaults.
Note: The 2FA implementation is still not there (😢 I just had the views) and this is delaying testing on other systems of the application. I will skip 2FA for V4.0.0.beta.9 so we can test the other stuff right now.
Property autofocus has been added to form elements at login, signup and account/*. This will focus the user input with a blinking text on page load. This saves one click and makes the experience a little bit better.
