Release notes for xrdp v0.9.17 (2021/08/31)

General announcements

  • Running xrdp and xrdp-sesman on separate hosts is still supported by this release, but is now deprecated. This is not secure. A future release will replace the TCP socket used between these processes with a Unix Domain Socket, and then cross-host running will not be possible.

New features

  • The IP address, port, and user name of NeutrinoRDP Proxy connection are logged in xrdp.log - these connections may not have a sesman log to use (#1873)
  • The performance settings for NeutrinoRDP can be now configured (#1903)
  • Support for Alpine Linux in startwm.sh (#1965)
  • clipboard: log file transfer for the purpose of audit (#1954)
  • Client's Keyboard layout now can be overridden by xrdp configuration for debugging purposes (#1952)

Bug fixes

  • PAM_USER environment variable is not set when using pam_exec module (#1882)
  • Allow common channel settings to be overridden for modules as well as chansrv (#1899)
  • The text only-copy/paste interface for the VNC module (used only when chansrv is not active) has been improved (#1900)
  • The unsupported tcutils utility has been removed (#1943)
  • The quality of TLS logging has been improved (#1926)
  • Keyboard information is now passed correctly through NeuutrinoRDP, and can be overridden if required (#1934)
  • A message is now logged in the sesman log for unsuccessful login attempts detailing the user used (#1947)

Internal changes

  • astyle formatting is now checked during CI builds (#1879)
  • Generalise development build options, and add --enable-devel-streamcheck (#1887)
  • Now uses cppcheck 2.5 for CI builds (#1938)
  • The SCP protocol is now using a standard struct trans for messaging rather than its own thing (#1925)

Changes for packagers or developers

  • The --enable-xrdpdebug developer option has been replaced with finer-grained --enable-devel-* options. Consequently, specifying --enable-xrdpdebug is now an error (#1913)

Known issues

  • On-the-fly resolution change requires the Microsoft Store version of Remote Desktop client but sometimes crashes on connect (#1869)
  • xrdp's login dialog is not relocated at the center of the new resolution after on-the-fly resolution change happens (#1867)

Release notes for xrdp v0.9.16 (2021/04/30)

New features

  • On-the-fly resolution change now supported for Xvnc and Xorg (#448, #1820) - thanks to @Nexarian for this significant first contribution. See the following YouTube video for a demo.

Changes for packagers

Known issues

Other topics

Pulseaudio modules has been removed from xrdp source tree since it is actually independent and not part of xrdp. The repository has been moved to: https://github.com/neutrinolabs/pulseaudio-module-xrdp
