2.2.0

  • Rework of sliced AVL+ trees (BatchAVLProverManifest / BatchAVLProverSubtree)
  • Batch Merkle proof implementation
  • AuthenticationTreeOps.logError
  • Scala, scorex-util, Guava, BouncyCastle dependencies updated
  • example app in SparseMarkleTree reworked into tests (#38)
  • switch from sbt-git to sbt-dynver
  • migration from Travis to GA

2.1.8

  • Guava's comparator for byte arrays is used instead of custom old one ( #74 )
  • Scala 2.13 support ( #75 )

2.1.7

  • remove logback dependency, add sbt-dependency-graph plugin
  • add git versioning, cross-build with scala 2.11, auto sonatype publishing(WIP); remove sbt-lock

2.1.6

  • Manifest deserialization now checks that valueLength is not negative

2.1.5

  • Fix for "BatchAVLProverManifest changes its properties after serialization/deserialization" bug (#58)

2.1.4

  • Minor update with dependencies update (Guava 21.x, scorex.utils 0.1.1)

2.1.3

  • Always explicit encoding in .getBytes String method
  • Base* and logging are moved to scorex-utils

2.1.2

  • Base58: empty string allowed as parameter
  • Reworked Base16 implementation has much better performance
  • Minor changes in MerkleTree implementation

2.1.1

  • Bugfix release: a bug in double rotation processing in AVL+ tree implementation has been fixed

2.1.0

  • AVL+ tree serialization, see BatchAVLProverSerializer class
  • Possibility to get list of removed nodes, see removedNodes() in BatchAVLProver
  • Better Base58 performance
  • Initial implementation of sparse Merkle trees

2.0.5

  • randomWalk() in BatchAVLProver can accept external randomness via an optional parameter

2.0.4

  • improved performance of Base58-related operations

2.0.3

  • treeWalk() and randomWalk() methods in BatchAVLProver

2.0.2

  • generateProof() -> generateProofAndUpdateStorage() in PersistentBatchAVLProver, new optional parameter for this method (to pass additional key-value pairs into storage)
  • additional optional parameter for PersistentBatchAVLProver (with the same meaning as above)

2.0.1

  • Style fixes
  • version method signature change in VersionedAVLStorage
  • rollbackVersions method in VersionedAVLStorage
  • AdProof was renamed to SerializedAdProof

2.0.0

  • Shapeless dependency removed
  • Using tagged types instead of Array[Byte], suppertagged microframework is used for that
  • BouncyCastle 1.58
  • Rollback changes from 1.3.3

1.3.3

  • version method signature change in VersionedAVLStorage
  • rollbackVersions method in VersionedAVLStorage

1.3.2

  • prover() in PersistentBatchAVLProver (don't store the ref, it is mutable!)
  • No constructor for PersistentBatchAVLProver anymore, use PersistentBatchAVLProver.create

1.3.1

  • Added hash functions Whirlpool, Skein and Stribog from BouncyCastle

1.3.0

  • performOneOperation() return value type fix in PersistentBatchAVLProver
  • Instead of imported Java implementations for hash functions, BouncyCastle to be used for hash functions
  • Because of previous item, most of hash functions were removed. Scrypto has SHA-256, Blake2b-(256/512) and Keccak-(256/512) wrappers only in this version.

1.2.3

  • Index checking in Merkle proof generation
  • PersistentBatchAVLProver interface improvements

1.2.2

  • MerkleTree and MerkleProof implementation - static Merkle trees

1.2.1

  • BatchAVLVerifier now has an interface for traversal through its tree, extractNodes() and extractFirstNode() functions
  • Parameter valueLength is now optional
  • Better interface for authenticated dynamic dictionaries, namely Operation/Lookup/Modification families

1.2.0

  • Versioned deterministic Merkle trees with in-memory or on-disk storage
  • Authenticated skiplists
  • Authenticated AVL trees
  • Commutative hash
  • It is possible to get results of hash and signing functions wrapped in statically sized byte array using Sized from Shapeless
