Hi Sean,

I do have plans to bring libpng 1.5 into v3p, but it may take me a few weeks. 

vil1 seems to be affected as well.  Taking this chance,  I wonder how many people are still using vil1.  If few people do, I may consider not to upgrade vil1.

Regards,
Gehua Yang.

Hi all,

Is there any news on this issue?

Will vxl be updated to be compatible with libpng 1.5?

Thanks,
