This blog serves as advance notice of our intention to stop supporting php versions 5.5, 5.6 and our ongoing evaluation of 7.0.
For php 5.5 we intend to end support in January 2019.
This is already unsupported by php and we strongly recommend you upgrade off it as soon as possible. The release in February 2019 will be the first release that does not support php 5.5
For php 5.6 our TARGET is to end support in September 2019 (Oct release would support php 7.0+).
