v0.51.0

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.

Updating from v0.49.1

Erasure coding is available in experimental mode. To enable it, set experimental.allow_ec flag in IR config.

Use IR configuration options:

• fschain.disable_autodeploy instead of deprecated fschain_autodeploy with reverted value, by default autodeploy is enabled now;
• mainnet.enabled instead of deprecated without_mainnet with reverted value, by default mainnet is disabled now;
• mainnet.disable_governance_sync instead of deprecated governance.disable;
• mainnet.extra_fee instead of deprecated fee.main_chain;
• mainnet.contracts instead of deprecated contracts;
  Old options are still supported but will be removed in future releases.

SN config option node.persistent_sessions.path now is deprecated and used only for migration. Sessions are stored in node.persistent_state.path option now.

Write cache migration from pre-0.46.0 format is no longer supported, use some earlier version if you still have write cache database with objects.

Contracts autoupdate doesn't support pre-0.20.0 contract versions corresponding to NeoFS 0.43.0 release. Update from earlier versions using 0.49.1 first.
