They are months behind Chromium sources. But that is exactly what I am talking about! Chrome 100 was released 2022-03-29: https://chromereleases.googleblog.com/2022/03/stable-channel-update-for-desktop_29.html An additional security update for it was released 2 weeks later, 2022-04-11: https://chromereleases.googleblog.com/2022/04/stable-channel-update-for-desktop_11.html These fixes (those that are relevant to QtWebEngine to begin with – several of the bugs affect only Chromium UI code that is *not* part of QtWebEngine) have been backported to upstream qtwebengine-chromium.git (87-based branch, the one used in QtWebEngine 5.15.x since 5.15.3) on 2022-05-19: https://code.qt.io/cgit/qt/qtwebengine-chromium.git/log/?h=87-based That is only 1 to 1½ months later. The release has been tagged in Qt git on 2022-06-06: https://code.qt.io/cgit/qt/qtwebengine.git/tag/?h=v5.15.10-lts and announced on 2022-06-07: https://www.qt.io/blog/commercial-lts-qt-5.15.10-released That is about 2 months after the upstream Google fixes. So your unqualified "months behind", while technically correct (because 2 is already a plural, at least in English), makes it sound worse than it actually is. The Fedora QtWebEngine updates actually take longer than that to get out (and the upstream and downstream delays add up). The reason it takes time to get security fixes out is because Qt actually maintains stable branches, unlike Google, and backports security fixes instead of forcing everyone to upgrade. Google, on the contrast, deliberately withholds security fixes until a new major version reaches stable, in order to have a levy to force people to upgrade. (The fact that these fixes are not included in the betas, but only dropped into the stable release, also makes the beta testing quite pointless and compromises the stability of the stable releases.) Even a new major Qt release does not ship with the very latest Chromium, but with a bugfixed stable version with already some security fixes backported. (The QtWebEngine Chromium branches are quite similar in spirit to the Firefox ESR/LTS branches.) Qt also does not release a new version every 2 weeks – thankfully, because we are already struggling to keep up with the releases every 2-3 months! I cannot imagine how it would look if we had to ship an update every 2 weeks.
