Hello PHP developers! In December 2016, we 
announced the stable release of the new ads PHP library and the deprecation of the old one. This is a reminder to upgrade to the new library by 
July 31, 2017.
The new PHP library has many improvements such as support of namespaces and 
Composer installation. It is currently available as the 
master branch on GitHub. We also provide an 
upgrading guide to help you during this upgrade.
The old library has been moved to the 
deprecated branch with reduced support and will reach end of life (EOL) on 
July 31, 2017. We recommend you complete your upgrade before that date. Past this date, the deprecated branch can still be used until all of the AdWords / DFP API versions it supports are sunset, but we will not add support and examples for new API versions, nor fix any bugs.
If you have questions about upgrading or need help, as always, feel free to ask on the GitHub 
issues page. If you have questions regarding AdWords or DFP API, please drop us a line on the 
AdWords or 
DFP API forums.
