Shiny Server 1.5.4.869 and Shiny Server Pro 1.5.4.872 are now available.

Both the new Shiny Server and Shiny Server Pro releases include bug fixes and enhancements, and we recommend upgrading at your earliest convenience.

Shiny Server 1.5.4.869

• Clickjacking protection can now be enabled using the frame_options directive. This directive was already available in Shiny Server Pro, but is now available in Shiny Server as well.
• A bug that caused "Error: Can't set headers after they are sent." to appear in error logs was fixed.
• Several bugs in license-manager were fixed.

Shiny Server Pro 1.5.4.872

• The “utilization scheduler” component, which manages the way requests are routed to R processes, has been significantly improved. It has been made more robust, and applications now respond more efficiently to increased load.
• auth_pam: The performance of multiple simultaneous logins was improved.
• auth_ldap: A bug was fixed that caused LDAP to return no groups when a username contained a backslash.
