This is a patch release.

Changes since 0.9.2:

• the upstream names where reverted to the legacy (pre 0.9.1) behaviour to avoid breaking existing setups that rely on them. A new optional SHA1_UPSTREAM_NAME environment variable enable 0.9.2 behaviour if needed. See #1736 for more information.

Default behaviour:

# example.com
upstream example.com {
  server 172.16.0.2:80;
}

server {
  server_name example.com;
  #[…]
  location / {
    proxy_pass http://example.com;
  }
}

With SHA1_UPSTREAM_NAME set to true:

# example.com
upstream 0caaf24ab1a0c33440c06afe99df986365b0781f {
  server 172.16.0.2:80;
}

server {
  server_name example.com;
  #[…]
  location / {
    proxy_pass http://0caaf24ab1a0c33440c06afe99df986365b0781f;
  }
}

Plus some CI and docs updates.
