xrdp v0.9.18

Release notes for xrdp v0.9.18 (2022/01/10)

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.
• Special thanks for @trishume for contributing code to the RFX codec

New features

• Backgrounds and logos on the login screen can now be zoomed and scaled (#1962)
• Small change for Alpine Linux support (#2005)
• loongarch support (#2057)
• Improved Fail2ban support (#1976)

Bug fixes

• Logging is improved for security protocol level decisions (#1974, #1975)
• An unnecessary log error message which is always generated when running neutrinordp has been removed (#2016)
• An incorrect development log message has been fixed (#2074)

• Remote drive redirection now works if printer redirection is also requested by the client (#327)

• A config value has been added which allows copy-pasting of files to work with Nautilus for GNOME 3 versions >= 3.29.92 (#1994, #1996)
• Clipboard now works properly when files can't be read (#1997 #2001)
• (xorgxrdp v0.2.18) The screen is fully refreshed after initialising shared memory which should fix black screen problems like #1964

• Some minor memory leaks have been fixed (#2014 #2028)

Internal changes

• Some 64-bit packages are removed during the 32-bit CI build process in an attempt to make this more robust (#1985)

• Monitor processing unit tests for existing xrdp_sec function have been added (#1932)
• The librfxcodec has been updated as part of #2087, and also to add stack frames to assemble code to assist debugging

Changes for packagers or developers

• The --with-imlib2 option has been added. If xrdp is built with imlib2, the login screen supports more image formats for the background and logo, and better quality zooming and scaling (#1962)
