We announced a bit over one year ago that the long-term supported releases of Qt 5.15 will be available only for commercial license holders. Today we have released Qt 5.15.3 LTS, the first commercial only patch release to Qt 5.15 LTS series. As a patch release, Qt 5.15.3 does not add any new functionality but provides bug fixes and other improvements.
Compared to Qt 5.15.2, the new Qt 5.15.3 contains close to 250 bug fixes. All the applicable bug fixes are also part of the upcoming Qt 6.1 release targeted to be released in April.
We have adjusted the process of change files and instead of separate changelog for each module you can check the overview of all important changes and bug fixes in the Qt 5.15.3 from the release note found in the Qt Account portal.
Qt 5.15.3 is automatically visible for all commercial license holders in the online installer (maintenance tool). The source packages of Qt 5.15.3 are available via the online installer as well as the Qt Account. The offline packages for Qt 5.15.3 are available from the Qt Account portal.
If you want to access the source code repository, it can be done via the Codereview system. Just log in with a Qt Account that has a valid commercial license, and you will be able to access the LTS repositories. For more details, please check the instructions for accessing the commercial LTS repositories.
Qt for Device Creation images are also available for Qt 5.15.3 LTS. If you want to build yourself with yocto, use the meta-qt5 layer from the Qt repository. We have updated the yocto meta-qt5 layer of Qt 5.15.3 to point to the commercial LTS repositories. For more details, please check the instructions on using yocto with access to the commercial LTS repositories.
If you have any problems with the commercial LTS releases, please contact Qt Support. You can also create bugs to https://bugreports.qt.io, but in addition it is recommended to notify the support team about it.
Next commercial-only LTS patch release, Qt 5.15.4 is planned to be released at the end of April.
