docker-compose (1.5.1-1) unstable; urgency=medium With the introduction of variable substitution support in the Compose file, any Compose file that uses an environment variable ($VAR or ${VAR}) in the command or entrypoint fields will break. Please see the 1.5.0 version section of /usr/share/doc/docker-compose/changelog.gz for details -- Felipe Sateler Sat, 14 Nov 2015 15:15:38 -0300 docker-compose (1.3.1-1) unstable; urgency=medium Compose since version 1.3.0 now uses labels to identify containers. This means that containers created by older versions are incompatible with newer ones, and that the daemon has to be at least version 1.6.0. Compose will refuse to start containers where it detects that they were created with older versions. Please see the Upgrading section of /usr/share/doc/docker-compose/install.md for instructions on upgrading your containers. -- Felipe Sateler Sun, 28 Jun 2015 00:24:29 -0300
