Dynamic color settings
On Windows, a new “System” display theme uses light or dark colors for the application window to match the system app mode setting. On all platforms, a new system color scheme uses a light or dark session background depending on the system's display setting.

New Session Manager icons (Windows)
The icons in the Session Manager and Connect dialog now reflect the session’s protocol, making it easier to visually identify the session type prior to connecting.
Resizable dialogs
The Map Selected Key, Map Button, Command Properties, and Text Import Wizard dialogs can be resized to fit more information and the size will be remembered the next time the dialog is opened.

RDP enhancements (Windows)
RDP sessions can redirect audio, printers, clipboard, and keyboard shortcuts.
Administrative options (Windows)
A new administrative option helps enforce security best practices by preventing host keys from being saved. An administrative option that disallows the anti-idle capabilities gives administrators more control over system resources.
Algorithm support
SecureCRT now supports x509v3-ecdsa-sha2 algorithms for keys stored in a .pfx or .p12 file (RFC 6187).
Text file import options
Text file imports now provide options to specify a saved credentials title, a port number, and a session description.
Other enhancements
On Windows, the default settings for Local Shell sessions can be configured. On all platforms, an optional description can be added to buttons on a button bar and commands in the Command Manager.
