Changelog

Version 1.1.0

Added

• Jump hosts. Reach a server through another saved server, like ssh -J (ProxyJump). Choose a jump host when editing a server. Chains of several jump hosts work, and each server keeps its own login, saved password or key, and host key check. Needs Pro.
• Server cards show which jump host a server goes through (“via james-server”).

Changed

• Clearer errors. Failures now name the jump host involved, and Centra explains when a server closes the connection before login or a jump host cannot forward to the target.
• On key cards, the Copy, Share and Install buttons now fit on one line on narrow phones.
• Deleting a server that others jump through makes them connect directly.

Fixed

• Supports the 16 KB memory page sizes that Google Play requires for Android 15 and later.

Version 1.0.1

Changed

• Targets Android 16, as Google Play now requires.
