* 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
* Both inbound and outbound clipboards can now be restricted for text, files or images [Sponsored by @CyberTrust@clear-code and @kenhys] (#2087)
## Bug fixes
* [CVE-2022-23613](https://www.cve.org/CVERecord?id=CVE-2022-23613): Privilege escalation on xrdp-sesman (This fix is also in the out-of-band v0.9.18.1 release)
* The versions of imlib2 used on RHEL 7 and 8 are now detected correctly (#2118)
* Some situations where zombie processes could exist have been resolved (#2146, #2151, #2168)
* Some null-pointer exceptions which can happen in the logging module have been addressed (#2149)
* Some minor logging errors have been corrected (#2152)
* The signal handling in sesman has been reworked to prevent race conditions when a child exits. This has also made it possible to reliably reload the sesman configuration with SIGHUP (#1729, #2168)
## Internal changes
* Versions 0.13 and later of checklib can undefine the pre-processor symbol `HAVE_STDINT_H`. The xrdp tests now build successfully against these versions (#2124)
* OpenSSL packaging changes (#2130):-
- The OpenSSL 3 EVP interface is now fully supported
- When building against OpenSSL 3, an internal implementation of the RC4 cipher is used instead of the implementation from the OpenSSL legacy provider
- The wrapping of the OpenSSL library has been improved which should make it simpler to provide an alternative cryptographic provider in the future, if required
- The logging of TLS/non-TLS security negotiation has been improved
* cppcheck version used for CI bumped to 2.7 (#2140)
* The `s_check()` macro which is easily mis-used has been removed (#2144)
* Status values for the DRDYNVC channel are now available in `libxrdp/xrdp_channel.h`
## Changes for packagers or developers
* On OpenSSL 3 systems, there is now no need to build with the `-Wno-error=deprecated-declarations` flag
## 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)
* 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.

## Changes for packagers
These changes are likely to impact operating system package builders and those building xrdp from source.
* (#1843, #1860) This release introduces an additional optional compile-time dependency on the `check` unit test framework. The dependency is recommended when packaging for compile-time tests.
* (#1858) The executables `memtest` and `tcp_proxy` are no longer copied to the sbin directory on a package install.
## 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)
* [CVE-2020-4044: Local users can perform a buffer overflow attack against the xrdp-sesman service and then impersonate it](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-4044)
This release fixes a trivial packaging issue #848 occurred in v0.9.3. The issue only affects systemd systems. This release is principally for distro packagers or users who compile & install xrdp from source.
Users who running xrdp on these systems don't need to upgrade from v0.9.3 to v0.9.3.1.
