- Fixed a bug where `extra_hosts` values would be overridden by extension
  files instead of merging together

- Fixed a bug where the validation for v3.2 files would prevent using the
  `consistency` field in service volume definitions

- Fixed a bug that would cause a crash when configuration fields expecting
  unique items would contain duplicates

- Fixed a bug where mount overrides with a different mode would create a
  duplicate entry instead of overriding the original entry

- Fixed a bug where build labels declared as a list wouldn't be properly
  parsed

- Fixed a bug where the output of `docker-compose config` would be invalid
  for some versions if the file contained custom-named external volumes

- Improved error handling when issuing a build command on Windows using an
  unsupported file version

- Fixed an issue where networks with identical names would sometimes be
  created when running `up` commands concurrently.
