+1.5.0 (2015-11-02)

|
------------------
|
|
|
|
|
|
+**Breaking changes:**
|
|
|
+
|
|
|
+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:` field will break.
|
|
|
+
|
|
|
+Previously these values were interpolated inside the container, with a value
|
|
|
+from the container environment. In Compose 1.5.0, the values will be
|
|
|
+interpolated on the host, with a value from the host environment.
|
|
|
+
|
|
|
+To migrate a Compose file to 1.5.0, escape the variables with an extra `$`
|
|
|
+(ex: `$$VAR` or `$${VAR}`). See
