Chatterino v2.5.2 (next release) will be the last to support Qt5

[pajlada]

We are nearing the release of Chatterino v2.5.2. We intend that release to be the last release that officially supports building with Qt5. This means we'll stop testing Qt5 builds, and we'll remove some code that we've retained in Chatterino specifically to build on Qt5. If this is a problem for you or your package, let us know here.

I haven't tried to follow the instructions yet, but it looks like BUILDING_ON_MAC.md needs an update. It refers to Qt 5.

Which versions of Qt6 can we compile with? Debian 12 (current LTS, from backports repo) has 6.4.2, latest being 6.8.0. Is this a problem?

If Debian and Ubuntu don't fix their Qt version, then we need 6.5.3 or later (https://github.com/Chatterino/chatterino2/issues/5517#issuecomment-2241199083). One might be able to use libc++ as an alternative. 6.5 is a decent requirement (all overviews) – 6.6 only adds some overloads for std::chrono afaik.

6.4.3 is the latest version to easily support macOS 10.15, I'd like to support that for another release

We don't build for that version. Our builds require at least macOS 14.0 right now and even a year ago, we required 13.0:

It's not that it's impossible to support 10.15 now, it's that after more than one year, no one complained that builds for 10.15 were missing.

We don't build for that version. Our builds require at least macOS 14.0 right now and even a year ago, we required 13.0:

Just because the build is named that way doesn't mean it runs on that version (the macOS build is mostly opaque). I could also create a Chatterino-WindowsXP.zip. Even though the libraries say they require newer versions, the loader doesn't seem to check this.

Since there are no usage statistics on macOS, we can't say how many people are using each version (Apple stopped changing its user-agent). The argument I heard was "I know people on 10.15 and there's no urgency".

There's 1 guy in the discord who constantly informs us when we break the 10.15 build, so as far as I know it currently still works
