### Changed
- Priority order in the Morph client (#1648)
### Fixed
- Losing request context in eACL response checks (#1595)
@ -28,6 +30,9 @@ Changelog for NeoFS Node
- `google.golang.org/grpc` to `v1.48.0`
### Updating from v0.30.0
Change `morph.endpoint.client` priority values using the following rule:
the higher the priority the lower the value (non-specified or `0` values are
interpreted as the highest priority -- `1`).
