accidentally replied only to Tuukka (QtC). forwarding to ML so it gets where it was supposed to be.
to be clear, the problem is the admission of support, its left open, i saw that Giuseppe from KDAB also was on that ball, what happens after 6.8, its only listed as supported - Even though not part of the release configuration, intention is to keep Qt 3D working also with Qt 6.8 the wording I'm looking for is 'working with Qt at-least until 7.0' and when that wording comes into play, it can just as well still be left where it's in dev.. so we got a train wreck incoming, that likely will be QtC pushing this over to KDAB after 6.8, so how long after a 6.x release is it acceptable that the release of the Qt3D module releases, will QtC still host the tarballs, will the development be done on Qts git trees? that is really a question that it seems that only KDAB can answer since it seems that QtC is pushing it over to them without actually saying it open, but any lag upstream gets even bigger on the way downstream... /Björn >> first mail that went wrong From: Björn Strömberg <bjorn.stromber...@gmail.com> Date: Thu, Mar 28, 2024 at 2:53 AM Subject: Re: [Development] Removing Qt 3D from release configuration in dev branch To: Tuukka Turunen <tuukka.turu...@qt.io> So now qt-6.x is effecively only promise backwards-compatible module wise to 6.8? As written it's open to interpretion afterwards... Or will a breaking change in dev vs Qt3D really enforce no release of next point release unless the ext module actally is API compatible with the new 6.x minor? Its unclear from the mail. This sounds like it will become a "he said, she said" type of thing between QtC and KDAB, when stuff starts tilting... In clear words can a Qt6 released module be dropped before Qt-7.0? I might read the text like "the devils advocate" and look for errors, but since the shitty thing with the LTS release of patch releases as open source from Qt-5.15 forward, I dont trust these "stealth" changes, from user of the libraries perspective, its the reason i now follow the dev ml to get info about it before getting bitten. Personally i was about to use qt3d in a new project since it was shipped as a module without any deprecation warnings in Qt6, so i assumed life of it till 7.0 without hassle. But now i will look outside the Qt Eco system for alternative designs before deciding path to take for end design. I might even ditch the whole Qt subsystem in due time, or atleast design for the possibility. If this is allowed once what will be the next thing that gets dropped? First was open source LTS support, now Qt3d is on the chopping blocks, so that makes module support uncertain. Due to the combination.
