# Cloud Sign 1.5.0

This latest version of cloud sign brings some under the hood improvements to increase stability and reliability of the platform. Notably, it brings secure web socket communication between cloud sign and the Wallet-as-a-Service (Palisade) platform for more consistent low latency key generation and signing times.

Required
Migration is **mandatory** for all customers.

## Notes

Since this change brings secure web socket communication, the environment variable `BATCH_WINDOW_SECONDS` is no longer used and is deprecated.

## Actions

* [ ] Backup shard databases and cloud sign environment variables.
* [ ] Update cloud sign docker image version to `1.5.0`.
* [ ] Remove `BATCH_WINDOW_SECONDS` environment variable from Cloud Sign (if used).
* [ ] Deploy updated image.
