The first release of the PHP buildpack after 2020-08-07 will no longer include NGINX versions 1.17.x. These NGINX versions will no longer be supported upstream. Please migrate your PHP apps to supported versions of NGINX before that time.
Note: As 1.17.x is the current default version of NGINX in the buildpack, the default NGINX version will be updated to 1.19.x as a part of this removal. If you’d like to use a different NGINX version, please configure your application to select that version.
As always, the buildpacks team is happy to answer questions you may have about this deprecation in the #buildpacks Slack channel.
