Its GOA. 

But one thing I like to mention here is that: v1 api endpoints are 
still working for calDAV & cardDAV 
with basic http authentication (only for whitelisted applications, I 
suppose). For example,

"syncevolution --print-databases \ 
	backend=carddav \ 
	username=username at gmail.com password=****** \	
	syncURL=https://www.googleapis.com:443/ "

gives same default database as this:

"syncevolution --print-databases \ 
	backend=carddav \
	username=goa:username at gmail.com \
	syncURL=https://www.googleapis.com/.well-known/carddav ".

Here is the test setup for both (caldav):

Yes. Its Google Web interface.

That explains everything. Also also from 1.4 release notes, its crystal 
clear:

"Instant Messaging information is supported by both sides with
different vCard extensions; the server stores these extensions without
showing the information, while SyncEvolution drops the data sent by
the server."

I think, I spoke too soon here. After reformatting local & remote 
databases I
couldn't able to reproduce the problem.

I attached the log. But I don't think further investigation on this is 
necessary,
as you explained, how some client properties ((CALURI, CATEGORIES, 
FBURL, GEO)
are not supported by the server (yet).

Thanks.
