v5.3.0

• Keybase for iPad is here!
• The Crypto tab can open and save .saltpack files
• You can now search for open teams using chat search
• Many performance improvements and bug fixes

Note: On some Linux platforms, specifically with window managers like i3wm and others without support for StatusNotifier, the system tray icon will no longer appears, so if Keybase is minimized, it must be restarted to display it again, though it is running in the background. Two workarounds (in official Keybase packages) are running /opt/keybase/Keybase and with systemd, systemctl --user restart keybase.gui). We're working on a better UX around this experience.
