Ok, here’s the list of public headers that got added between 5.4 and 5.5.
I used the command below

git diff --name-status origin/5.4..origin/5.5 src | grep '^A' | grep "\.h"
| grep -v "_p.h" | grep -v 3rdparty | grep -v plugins

The list of headers that we need to go through is then:

Ok, here’s the list of public headers that got added between 5.4 and 5.5.
(generated using
git diff --name-status origin/5.4..origin/5.5 src | grep '^A' | grep "\.h"
| grep -v "_p.h" | grep -v 3rdparty | grep -v plugins)

The list of headers that we need to go through is then:

qtbase
A src/network/ssl/qsslellipticcurve.h
A src/network/ssl/qsslpresharedkeyauthenticator.h

qtmultimedia

A src/multimedia/camera/qcameraviewfindersettings.h
A src/multimedia/video/qabstractvideofilter.h
A src/qtmultimediaquicktools/qsgvideonode_yuv.h

qtwebengine

A src/webenginewidgets/api/qwebenginedownloaditem.h
A src/webenginewidgets/api/qwebengineprofile.h
A src/webenginewidgets/api/qwebenginescript.h
A src/webenginewidgets/api/qwebenginescriptcollection.h

For reference the full set of output of the script is attached, but most
of the files are not relevant to review for different reasons.



There are a couple of new modules as well:

Qt Canvas3D: Basically just a QML import exposing WebGL to QML.
Implemented a w3c/khronos standard, so not much to review here.

Qt 3D: In technology preview, API not yet frozen

Qt Location: The APIs underwent some changes from the 4.8 mobility API,
but the module got a good review during Nokia times.



I’ll get to reviewing the added files now, but others feel free to have a
look as well.

Cheers,
Lars
