But not in 5.8.0. So, effectively, in no released 5.8 version.

There's no need. You can use the MSVC 2015 installer.:

Do you mean "support" as in "it works" or as in "it's tested in the CI".

Because if you mean the former, it's already supported in 5.8.

If not "before we ship 5.10", it will be the compiler of choice for Linux 
distros in 2018, which is when 5.10 is supposed to be used.

That said, we will be testing ourselves (I've already updated my openSUSE 
Tumbleweed for it), so it's not like it will be broken. I've also been 
building Qt 5.9 with Clang 5.0 (trunk).

They are already supported. Feel free to compile Qt with the appropriate -arch 
options. Do you mean you want them in CI and want us to start shipping binaries 
for android amd64 and arm64?

I'm not sure there's enough 64-bit devices out there to justify it yet. Android 
moves very slow...

I really don't like how we use the term "support" in these emails because it's 
rather misleading. We use it to mean "tested in CI", whereas I (and most of the 
world, as far as I can tell) read it as "the code exists and is functional". 
"Removing support" to me means actively removing the code which makes something 
functional.

As an Open Source project, we need to keep in mind that dropping first party 
"support" for something means little to nothing unless we actually delete the 
associated code as well and refuse patches to re-add it, because people can 
always build their own copy of Qt, and commercial support will obviously still 
answer queries for most definitions of "unsupported", making the term 
"unsupported" a little meaningless. Perhaps we can start using the term "tier 1 
support" as a synonym for what we actually mean by "support", in order to be 
more clear? I really liked the notion of tiered support that we used to have 
but it seems to have gone missing...

Something like the following seems nice:
Tier 1 - the most rigorously tested configurations, tested in CI
Tier 2 - we actively try to make it work but it's a lower priority; 
will make and accept patches and provide support but isn't tested in CI
Unsupported - we remove code that makes the functionality work; will 
refuse any related patches, commercial support refers queries to a separate 
(paid) business engagement

Anyways, iOS 11 will likely drop support for 32-bit applications entirely (i.e. 
they will not launch because 32-bit system libs will be GONE). So I agree we 
should stop shipping 32-bit slices in our binary distributions of Qt for iOS. 
We should not deliberately break 32-bit support though (and it's hard to do 
this accidentally anyways).

> - Drop macOS 10.10 support (we are adding 10.13 or whatever, and thus 
> supporting three latest ones means dropping one)

Well, the plan is to keep 10.10 supported in 5.10, because we've dropped a 
macOS release with every release of Qt since 5.6 on, and we have to slow down 
since Apple's release cadence is annual and ours is bi-annual, or we will end 
up supporting a negative number of OSes eventually :)

Current list is:
- Qt 5.6 - supports macOS 10.7 and up
- Qt 5.7 - supports macOS 10.8 and up
- Qt 5.8 - supports macOS 10.9 and up
- Qt 5.9 - supports macOS 10.10 and up

Planned:
- Qt 5.10 - supports macOS 10.10 and up, deprecates macOS 10.10
- Qt 5.11 - supports macOS 10.11 and up

By the way, "supported" here means we set the compiler and linker flag stating 
the minimum version. We actually REMOVE the code for older versions. 
"Supported" is not synonymous with "tested in CI", and not being tested in CI 
does not imply "unsupported".

If the quality of our 10.10 support suffers because it is not tested in the CI, 
then that's that. It would follow well with our usual practice of deprecating 
the earliest platform one release before removing it outright.

But it will still be "supported" as a deployment platform. I agree that we can 
remove it from the CI and maybe mark it as a deployment-only platform. (so 
10.11 SDK is required, and deploys to 10.10)

Apple does not ever release updates to older release series, so since 8.3 
already exists, this is guaranteed to remain 8.2.1.

How do you know it won't be called macOS 11? ;)

The purpose of the preview release *IS* to use it for testing so that you 
can say your product supports the final version (according to Apple). We should 
provision a VM for the first developer preview and update it throughout the 
beta cycle until the final release. So this should not be a problem for us with 
FF in August unless Qt 5.10 releases before macOS Next does.

Just for the record: make sure not to drop CI for macOS 10.10 - that 
version is still supported in Qt 5.10. Tentative plan for 5.11 would be to drop 
10.10 support.

How do you know it won't be called macOS 11? ;)

The purpose of the preview release *IS* to use it for testing so that you 
can say your product supports the final version (according to Apple). We should 
provision a VM for the first developer preview and update it throughout the 
beta cycle until the final release. So this should not be a problem for us with 
FF in August unless Qt 5.10 releases before macOS Next does.

Just for the record: make sure not to drop CI for macOS 10.10 - that 
version is still supported in Qt 5.10. Tentative plan for 5.11 would be to drop 
10.10 support.

Re: [Development] Proposal for Qt 5.10 platforms and configurations changes

[Stottlemyer, Brett (B.S.)]

> Please refer to Qt 5.9 Supported platforms -> 
> http://doc-snapshots.qt.io/qt5-5.9/supported-platforms.html

That page has the following for QNX: “QNX 6.6.0, 7.0 (armv7le and x86)” 

As QNX 7.0 includes 64-bit support, are aarch64le and x86_64 supported on 5.9?  
If not, can they be added for 5.10?

Brett

That's because GCC 7 hasn't been released yet, but it will be soon,
and then it will be in almost every linux distro as a system
compiler before we ship Qt 5.10, so I think it would be quite wise to
have it in CI as soon as possible.

Giuseppe was asking on IRC for GCC 7 and Clang 4.  Which are quite bleeding 
edge for almost all distros at this point, I suppose; Arch recently got Clang 4 
but not GCC 7 yet.

Apple does not ever release updates to older release series, so since 8.3 
already exists, this is guaranteed to remain 8.2.1.

> macOS 10.12 xcode 8.2.1 -> xcode 8.3.1 (or the latest available)

8.3.2, please.

[Development] Proposal for Qt 5.10 platforms and configurations changes

[Heikki Halmet]

Hi,



Below we have proposal for changes in supported platforms and configurations 
from Qt 5.9 to 5.10.

Please comment if the proposal is insufficient or the changes are unacceptable 
somehow.



Please refer to Qt 5.9 Supported platforms -> 
http://doc-snapshots.qt.io/qt5-5.9/supported-platforms.html



LIST OF PROPOSAL CHANGES FROM 5.9 TO 5.10:

RHEL 7.2 -> RHEL 7.3 (Any benefits?)

OpenSUSE 42.1 -> OpenSUSE 42.2

Ubuntu 17.04 (Ubuntu 16.04 lts will stay in CI)

macOS 10.11 xcode 8.2 -> xcode 8.2.1 (or the latest available)

macOS 10.12 xcode 8.2.1 -> xcode 8.3.1 (or the latest available)

Windows 7 MinGW 5.3.0 -> MinGW 6.3.0

Embedded Linux (Boot2Qt) Yocto 2.2.1 & gcc 6.2 -> Yocto 2.3 & gcc 6.3

INTEGRITY GHS 2016.5.4 -> 2017.1.x

Support for Android 8 (if available on time)

iOS 11 support (if available on time. Current rumors -> september)



MacOS 10.13 will be released September 2017 hopefully. Feature Freeze for 5.10 
is at the beginning of August.

This means that we can only use Preview release of 10.13 for testing before 
final official release is out.

That can cause situation that we don't have enough time to get 10.13 in before 
5.10 release so we can't give guarantees that 10.13 will be supported in 5.10.



NOTE! We will commit to wanted platform and software changes as long as those 
are available straight after 5.9 release is out in the end of the May.
With all others we'll do the best we can but we can't commit that those will be 
supported in 5.10.
