Lost AppStore Premium License

This issue is Codinn Store version specific – you may lost your App Store Premium license after upgrade to Core Shell/ Tunnel 3.10 or later. It is required that reinstall 3.10 or later from App Store again, then switch back to Codinn Store version.

AWS EC2

Version 3.6 and later

The embedded OpenSSH in Core Shell/ Tunnel version 3.6.x was updated to version 8.8, you might be unable to connect servers with older SSH implementations.

OpenSSH 8.8 disables RSA signatures using the SHA-1 hash algorithm by default. Though there is a stopgap measure, we recommend you upgrade your SSH server or reconfigured with another key type (such as ECDSA or Ed25519).

To fix connection problems, first check your connection log.

PubkeyAcceptedKeyTypes and HostbasedKeyTypes directives are disappeared

In OpenSSH 8.5 and later, PubkeyAcceptedKeyTypes keyword was renamed to PubkeyAcceptedAlgorithms, similarly, HostbasedKeyTypes was renamed to HostbasedAcceptedAlgorithms.
