AFAIK LTS is for paying customers only. For mortal people there's no LTS, there're only promises that 6.3 is backwards-compatible (but then why people pay for LTS at all).
Qt 6.2.4 was released at 2022-02-17 and it's the last public available 6.2 version. 6.3 was released at 2022-03-16. For paying customers they released 6.2.8 few months ago, for example, but it's not available for everyone else.
I do not expect anything from them and I’m grateful to receive quality open source library for free with current terms as that’s infinitely better than having a proprietary library. I’m just merely trying to understand how Debian deals with thus situation.
That said, of course having upstream patches available for free, as it was in the past, would even be better.
