Thank you. Can you post an example of what doesn't work, and what code we 
didn't include into our snapshot?

Yes, I originally tried to rebase on Chromium 45 in June, but it was not 
stable enough to be useful for even a dev-branch so we rebased on 44 instead 
with an eye open for merging in 45 later if it looked to be simple and 
painfree. QtWebEngine 5.6 is now based on 45 and will stay on that (44 to 45 
was a very small chromium update, only plus/minus a million lines of code in 
the parts we import).

Chromium 47 or 48 going into the dev branch for Qt 5.7 sometime late this 
year, but again QtWebEngine 5.7 might end up with a newer version of Chromium 
than the first version it is rebased on (ideally whatever branch is on release 
track around the time of the Qt 5.7 alpha). Since there seems to be a lot of 
work by outside parties going on on QtWebEngine now, I will try to keep the 
list informed of merging plans in the future.

Best regards
`Allan
