Will libphonenumber be updated (5.3 is 2 years old)?

Hello,

I was just wondering if you plan to update to the latest release from Google? 
https://github.com/googlei18n/libphonenumber

All belgian mobile numbers are wrongly displayed (was fixed in 6.1) : https://github.com/googlei18n/libphonenumber/issues/433

Thanks for any news.
