Updating from v0.52.0

Drop policer.max_workers configuration, it's no-op since 0.52.0.

Use CLI object search command instead of object searchv2, functionally they are the same now and v2 variant will be removed in future.

Storage nodes no longer implement deprecated and insecure Search method, migrate to Searchv2 if needed.

Storage nodes no longer implement deprecated GetRangeHash method and neofs-cli object hash command has been removed.

GET now supports payload ranges. Migrate from deprecated RANGE requests to GET with range parameters, old ones are still supported but will be removed eventually.

Delivering performance optimizations and initial placement feature this release also brings with it much more powerful maintenance tools and a huge list of updates and fixes.

Updating from v0.51.1

SN config option node.persistent_sessions.path was deprecated since release 0.50.0 and has now been removed. Drop this config and associated file, migrate with 0.51.1 if needed. Sessions are stored in node.persistent_state.path DB now.

Delete storage.shards.resync_metabase config option from SN config, it's no longer used. Use neofs-lancet meta resync command if you need to resync metabase.

Delete replicator.pool_size config option from SN config, it's no longer needed.

Storage nodes no longer automatically migrate metabases from version 5 (NeoFS 0.46.0) to 6 (NeoFS 0.48.0) and from version 6 to version 7 (NeoFS 0.48.1), migrate using SN 0.51.1 or resynchronize with 0.52.0 if needed.

Storage nodes clean up objects that belong to unpaid containers. This means data will permanently be deleted from shards, recovery isn't possible.

copies_number parameter of object PUT request no longer has any effect. Use max_replicas setting of container's initial placement policy instead.

CLI --await flag is now deprecated for container commands. For servers supporting NeoFS API version starting from v2.21, the flag may be safely dropped. For older servers, success checks should now be done by polling with symmetric read command instead. Please note that this flag will be removed in a future release.

neofs-lens command was renamed to neofs-lancet to reflect that it now supports modifying storage state in addition to inspection. Replace neofs-lens references with neofs-lancet.

Added

Updated

• NeoGo dependency to 0.117.0 (#3829)
• neofs-contracts to 0.26.1 (#3832)

A number of important protocol updates are delivered with this release including mutable NEP-11 containers, synchronous container operations and session token version 2. Metabase optimizations make some operations like object deletion significantly faster. Object service optimizations also allow to squeeze some additional ops/s from hardware, most noticeably for RANGE requests and PUT into containers using erasure coding.

  They were removed in this version and using them will lead to failure to start the node.

Storage nodes no longer automatically migrate metabases from version 3 (NeoFS 0.44.0) to 4 (NeoFS 0.45.0) and from version 4 to version 5 (NeoFS 0.46.0), resynchronize or migrate using SN 0.50.2 if needed.
