Hello Polaris devs,
Those who run Polaris on a domain different than the domain hosting their SEP-1 stellar.toml must upgrade to this version to be in compliance with SEP-10 v3.0
For example, if you run Polaris on polaris.anchor.com but your TOML file is hosted at anchor.com/.well-known/stellar.toml, you must upgrade.
You can check out the documentation for the added environment variable.
readthedocs.io seems to be having some issues at the moment. Hopefully docs will be back up shortly.
