# Release notes for xrdp v0.10.0 (2024/05/10)
|
|
|
|
This section notes changes since the [v0.10 branch](#branch-v010) was created.
|
|
|
|
## General announcements
|
|
The biggest news of this release is that [Graphic Pipeline Extension](https://learn.microsoft.com/en-us/openspecs/windows_protocols/ms-rdpegfx/da5c75f9-cd99-450c-98c4-014a496942b0) also called GFX in short has been supported. xrdp v0.10 with GFX achieves more frame rates and less bandwidth compared to v0.9. There is a significant performance improvement especially if the client is Windows 11's mstsc.exe or Microsoft Remote Desktop for Mac. GFX H.264/AVC 444 mode and hardware-accelerated encoding are not supported in this version yet.
|
|
|
|
GFX implementation in xrdp is sponsored by an enterprise sponsor. @CyberTrust is also one of the sponsors. We very much appreciate the sponsorship. It helped us to accelerate xrdp development and land GFX earlier!

# Branch v0.10
|
|
|
|
This branch was forked from development on 2024-02-08 in preparation for testing and release of v0.10.1.
|
|
|
|
The changes in this section are relative to version v0.9.19 of xrdp.
|
|
|
|
## User changes
|
|
* The [x11rdp](/neutrinolabs/x11rdp) X server is no longer supported. Users will need to move to xorgxrdp (#2489)
|
|
* Running xrdp and xrdp-sesman on separate hosts is no longer supported.
|
|
* There are some changes to `xrdp.ini` and `sesman.ini` which break backwards compatibility. In particular:-
|
|
* `sesman.ini/Globals/ListenAddress` is not longer used. A warning message is generated if this is found in the configuration, but the configuration will continue to work.
|
|
* `sesman.ini/Globals/ListenPort` is now a path to a socket, or an unqualified socket in a default directory. If the old default value `3350` is found, a warning is generated and a default value is used instead. The configuration will continue to work.
|
|
* The `ip` and `pamsessionmng` parameters are no longer required in sections in `xrdp.ini` to locate the sesman port. Unnecessary usages of this parameter now generate warnings. The configuration will continue to work.
|
|
* The 'C' field for the session allocation policy has been replaced with `Policy=Separate`. This field is has a very specific specialist purpose, and will not be used by the vast majority of users. The renaming makes it much clearer what is happening (#2251 #2239). Any uses of the 'C' field will generate warnings, **and the configuration will require updating**
|
|
* The format of the date and time in the log file has been changed to ISO 8601 with milliseconds (#2386 #2541)
|
|
|
|
Users are urged to heed any generated configuration warnings and update their configurations. Later major versions of xrdp may remove these warnings, or introduce other behaviours for the affected parameters.
|
|
|
|

|
|
* cppcheck install script no longer installs z3 for cppcheck >= 2.8 (#2782)
|
|
* The physical desktop size information sent from the client is now recorded in more situations (#2310)
|
|
* Simple maintenance improvements (#2354)
|
|
* An opaque type is now used for the auth_info handle used by the sesman auth module (#2362)
|
|
* CI updates to cope with github upgrades (#2394)
|
|
* GUIDs created for new sessions are now compliant with RFC4122 random UUIDs (#2420)
|
|
* Some 'magic numbers' have been replaced with constants (#2421)
|

|
|
* The poll() system call now replaces select() for monitoring file descriptors (#2497 #2568)

|
|
* config_ac.h is now used consistently (#2667)
|
|

|
|
## Significant changes for packagers or developers
|
|
* The libscp.so shared library is replaced with libipm.so
|
|
* A new shared library libsesman.so contains shared code for sesman and related executables (#2601)
|
|
* The default setting for `--with-socketdir` is now `/var/run/xrdp` rather than `/tmp/.xrdp`. The new setting works for installations where `/tmp` is polyinstantiated ( see #1482 for more details)
|
|
* The permissions of the socketdir have changed from 1777 to 755 (owned by root). Within this directory are the sesman socket and user-specific directories. The user-specific directories store the session sockets used by each user (#2731).
|
|
It is recommended not to use the same `--with-socketdir` setting for v0.9.x and v0.10.x packages as the differing permissions can cause problems on package downgrades. See #3066 for an example of where this can be a problem.
|
|
* Passing `--disable-static` to `configure` prevents unused static libraries being installed by `make install`.
|
|
* The `simple.c` example xrdpapi program has been updated to work with logging changes, and is now built as part of the CI (#2276)
|
|
* If the `xrdp-mkfv1` utility is to be built, the switch `--with-freetype2` must be passed to `./configure`.
|
|
* Minimum supported autoconf version is now 2.69 (#2408)
|
|
* Add xrdp-sesman.system to distributed files (#2466 #2467)
|
|
* A developer-only utility to exercise the auth module selected at configure time has been provided (#2453)
|
|
* Extra executables have been added to this release in pkglibexecdir
|
|
* The default systemd unit files have been changed to no longer fork (#2672) |
