Heroku-16 and Cedar-14 stack images updated to support PostgreSQL 10 clients

Change effective on 11 January 2018

The Heroku Cedar-14 and Heroku-16 stack images have been updated:

  • The included PostgreSQL client tools and libraries have been updated to PostgreSQL 10, to go with PostgreSQL 10 support in Heroku Postgres.
  • All installed packages have been updated to their latest versions, to address a number of security advisories.

The new stack image will be rolled out automatically in the next 24 hours. You do not need to redeploy your app or restart your dynos.

See this Dev Center article for an overview of the libraries available on the Cedar-14 and Heroku-16 stack images.
