### Updating from v0.35.0 (old NeoFS)

You need to change configuration environment variables to `FROSTFS_*` if you use any.

New config field `object.delete.tombstone_lifetime` allows to set tombstone lifetime
more appropriate for a specific deployment.

Use `__SYSTEM__` prefix for system attributes instead of `__NEOFS__` 
(existed objects with old attributes will be treated as before, but for new objects new attributes will be used).
