Hi,

thanks explaining and your work on patches.

How can I disable deprecation warnings altogether ?

A workaround could be to disable them and only from time to time enable 
and check if there are deprecations to fix.

I'm waiting for 6.2 before trying to port my mobile apps - and porting 
would also take some time, so I have to deal with this for some months.

thx
