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 v1.0 release will replace the TCP socket used between these processes with a Unix Domain Socket, and then cross-host running will not be possible.

Security fixes

 - CVE-2023-40184: Improper handling of session establishment errors allows bypassing OS-level session restrictions (Reported by @gafusss)

Bug fixes

 - Environment variables set by PAM modules are no longer restricted to around 250 characters (#2712)
 - X11 clipboard clients now no longer hang when requesting a clipboard format which isn't available (#2767)

New features

No new features in this release.
Internal changes

 - Introduce release tarball generation script (#2703)
 - cppcheck version used for CI bumped to 2.11 (#2738)

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)");
