Hey everyone,
You might have heard that Windows 10 has officially reached its end of
life on 14.10.2025.
Due to the operating system's popularity Windows 10 is currently covered
in Microsoft's Extended Security Updates (ESU) program.
For consumers this means that the operating system will receive security
fixes until 13.10.2026, see for some information
https://www.microsoft.com/en-us/windows/extended-security-updates.
For commercial users the program will run for three years (until
10.10.2028) and comes with increasing costs per device per year, see
https://learn.microsoft.com/en-us/windows/whats-new/extended-security-updates.
Considering these time lines I think it is time to think about Windows
10 end of life in Qt. My suggestion would be to have 6.12 LTS as Qt's
last release that will include support for Windows 10. This should give
consumers a chance to use this version during their ESU period and the
LTS nature of this release will give commercial users enough time to
prepare for an operating system and Qt version change. With 6.12 LTS
phase (until 2023) we even go beyond Microsoft's promises for this
operating system.
Having said that I think we cannot drop support before 6.12. Users and
customers rely on Qt being available on that (still popular) operating
system.
To make users and developers aware of the looming removal of support I
would add a to our supported platforms page
(https://codereview.qt-project.org/c/qt/qtdoc/+/713611).
Any feedback on the topic is welcome. Do not hesitate to shout.
Best,
Olli
