2.0.0-pre-rc.20 (LTS)

Below is the list of changes that were introduced in RC20 long term-supported release candidate of Iroha 2.

New Features

• Soft fork recovery
• Runtime-definable permissions
• Executor and instruction visitor
• WSV snapshots via the SnapshotMaker actor for a fast restart without the block replay
• Domain ownership (domains now have the owned_by field)
• Server-side cursor fetch_size for query batching (used to be defined in the client configuration)

Removed Features

• Ursa support was discontinued in favor of iroha_crypto.
• Expressions were removed as well as the simplified data model API that has become obsolete.

Improvements

• Standardized the layout of blocks: introduced BlockBuilder and ProofBuilder, replaced VersionedCommittedBlock with SignedBlock, improved block lifecycle and state transitions.
• Standardized the layout of transactions: removed the Versioned prefix from versioned containers.
• Simplified the layout of Iroha 2 schema: every entry is now unique.

2.0.0-pre-rc.19 (lts-candidate)

The latest development in the private DLT.

Includes dynamic permission validators, an improved consensus engine, and various smaller improvements.

2.0.0-pre-rc.6 (LTS)

Long term-supported release candidate. We have reached a level of feature completeness, but want to ensure that things are working properly. This is the first major development milestone and we expect a lot of feedback with the option to re-architect some bits later down the line.

It can not:

• request proposals
• send votes(votes from such a node will be skipped)
• generate events of building block

RocksDB Metrics #1692

Healthcheck #1735

Added healthcheck interfaces via:

• http
• grpc
• metrics

General Fixes

Iroha v1.4-rc.1 fixes #1785 :

• Drop wsv flag behavior
• Signatory case insensetive checks
• Transaction status description from 5 byte to 1 byte if true or 0 byte if false
• Bloom filter in RDB
• RadixTrie enumerates nodes by prefix filter
• RDB 2-layer cache for WSV

Iroha v1.4-rc.2 fixes #1824 :

• Switched from optimistic to transactions database in RocksDB
• WSV and block store are now in different column families
• WSV schema version increased to 1.4.0

GitHub Action Docker tag #1609

Fixed sample config files (from max_rounds_delay to proposal_creation_timeout and deprecated DB connection string) #1662

Docs Fixes

Fixed broken links: build status, build guide, etc. #1318
