+### Breaking Change
+
+* Add `config` feature for crate `sailfish`. It is enabled by default. In previous
+  versions, the functionality enabled by the `config` feature was always available. If the
+  feature is disabled, any configuration files (sailfish.toml) are ignored by the template
+  compiler. This speeds up the compiler a bit, and decreases the number of dependencies
+  required, so it can be useful for applications that don't use sailfish.toml configuration
+  files and want to speed up their build process.
