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)
