Qt 6.8.0 Released 8th October 2024!


==Qt Task Tree - generic solution for automatic management of asynchronous tasks (C++), by Jarek Kobus==
Release blog: https://www.qt.io/blog/qt-6.8-released
TaskTree automatically manages a chain (or a tree) of asynchronous tasks of mixed types, including running processes, network queries, functions in separate threads, animations, timers, and so on... It's easily extensible with any other types of asynchronous tasks.


The recipe on how to create, run and manage the conglomerate of tasks is described in a declarative way in C++.
Announcement: https://lists.qt-project.org/pipermail/announce/2024-October/000518.html
=Contact Information=


The recipes are enclosed in copyable value-type objects and may be run many times, or be part of more general recipes.
{| class="wikitable"
 
!'''Role'''
The TaskTree is broadly used in QtCreator, for executing Build / Deploy / Run configurations, Locator filter, Clang tool, VCS commands, Autotests, driving Axivion plugin's communication and much more...
!'''Name'''
 
!'''Email'''
The TaskTree will be included in Qt 6.11 as a new '''QtTaskTree''' module.

== Release Notes ==
Release notes for the Qt 6.8 LTS Commercial release are available via Qt Account.  In Qt Account, select ''Downloads'' - ''Product: Qt'' - ''Version: <Qt Version>.''
 
== Getting Source Codes ==
The Qt 6.8 LTS Commercial source codes are available in the ''tqtc shadow repositories'' and their lts branches.
 
'''Note! To be able to clone the LTS sources, you must have a commercial license. An evaluation license does not provide access to the LTS sources.'''
 
=== Qt sources ===
To clone the Qt sources, follow the instructions:
 
# Register to Gerrit as instructed in [[Setting up Gerrit#How%20to%20get%20started%20-%20Gerrit%20registration|[1]]]. Some notes:
## If you just want to clone the sources, you need to follow the instructions in steps 1-3 and either set an SSH key (step 5) or an HTTP password (step 7).
## If you are going to contribute to the Qt Project, step 4 is mandatory.
# Login to Gerrit and follow the instructions in [[Getting Commercial Qt Sources|[2]]] to clone the LTS source codes.
 
=== Yocto environment ===
If you are using the Yocto environment, please see instructions in https://doc.qt.io/Boot2Qt-6.8/b2qt-meta-qt6.html#using-commercial-qt.
 
=== Troubleshooting ===
Here are some tips for the most common issues. Please note that as a commercial customer you can also contact our support team.
 
# Please check your license. The LTS branches require a commercial license. An evaluation license does not provide access to the LTS sources.
# If you have used to work with the public Qt 5 repositories, please note that LTS sources are available via tqtc shadow repositories and a Gerrit account is needed for accessing them. Log in Gerrit and set up your account as instructed in [[Setting up Gerrit#How%20to%20get%20started%20-%20Gerrit%20registration|[3]]].
# If you see the following error message at the end of the cloning command, it might refer to the network issues (for example, too slow connection): ''fatal: early EOF''  ''fatal: fetch-pack: invalid index-pack output'' Please wait a while and try again cloning sources.
