Changelog

0.12.0 (November 26, 2018)

BREAKING CHANGES

0.11.1 (October 29, 2018)

IMPROVEMENTS

  • Uses GoAmino v0.14

0.11.0 (September 7, 2018)

BREAKING CHANGES

  • Changed internal database key format to store int64 key components in a full 8-byte fixed width (#107)
  • Removed some architecture dependent methods (e.g., use Get instead of Get64 etc) (#96)

IMPROVEMENTS

  • Database key format avoids use of fmt.Sprintf fmt.Sscanf leading to ~10% speedup in benchmark BenchmarkTreeLoadAndDelete (#107, thanks to @silasdavis)

0.10.0

BREAKING CHANGES

  • refactored API for clean separation of mutable and immutable tree (#92, #88); with possibility to:
    • load read-only snapshots at previous versions on demand
    • load mutable trees at the most recently saved tree

BUG FIXES

  • remove memory leaks (#92)

IMPROVEMENTS

  • Change tendermint dep to ^v0.22.0 (#91)

0.10.0 (July 11, 2018)

BREAKING CHANGES

  • getRangeProof and Get[Versioned][Range]WithProof return nil proof/error if tree is empty.

0.9.2 (July 3, 2018)

IMPROVEMENTS

  • some minor changes: mainly lints, updated parts of documentation, unexported some helpers (#80)

0.9.1 (July 1, 2018)

IMPROVEMENTS

  • RangeProof.ComputeRootHash() to compute root rather than provide as in Verify(hash)
  • RangeProof.Verify*() first require .Verify(root), which memoizes

0.9.0 (July 1, 2018)

BREAKING CHANGES

  • RangeProof.VerifyItem doesn't require an index.
  • Only return values in range when getting proof.
  • Return keys as well.

BUG FIXES

  • traversal bugs in traverseRange.

0.8.2

  • Swap tmlibs for tendermint/libs
  • Remove sha256truncated in favour of tendermint/crypto/tmhash - same hash function but technically a breaking change to the API, though unlikely to effect anyone.

NOTE this means IAVL is now dependent on Tendermint Core for the libs (since it makes heavy use of the db package). Ideally, that dependency would be abstracted away, and/or this repo will be merged into the Cosmos-SDK, which is currently is primary consumer. Once it achieves greater stability, we could consider breaking it out into it's own repo again.

0.8.1

July 1st, 2018

BUG FIXES

  • fix bug in iterator going outside its range

0.8.0 (June 24, 2018)

BREAKING CHANGES

  • Nodes are encoded using proto3/amino style integers and byte slices (ie. varints and varint prefixed byte slices)
  • Unified RangeProof
  • Proofs are encoded using Amino
  • Hash function changed from RIPEMD160 to the first 20 bytes of SHA256 output

0.7.0 (March 21, 2018)

BREAKING CHANGES

  • LoadVersion and Load return the loaded version number
    • NOTE: this behaviour was lost previously and we failed to document in changelog, but now it's back :)

0.6.1 (March 2, 2018)

IMPROVEMENT

  • Remove spurious print statement from LoadVersion

0.6.0 (March 2, 2018)

BREAKING CHANGES

  • NewTree order of arguments swapped
  • int -> int64, uint64 -> int64
  • NewNode takes a version
  • Node serialization format changed so version is written right after size
  • SaveVersion takes no args (auto increments)
  • tree.Get -> tree.Get64
  • nodeDB.SaveBranch does not take a callback
  • orphaningTree.SaveVersion -> SaveAs
  • proofInnerNode includes Version
  • ReadKeyXxxProof consolidated into ReadKeyProof
  • KeyAbsentProof doesn't include Version
  • KeyRangeProof.Version -> Versions

FEATURES

  • Implement chunking algorithm to serialize entire tree

0.5.0 (October 27, 2017)

First versioned release! (Originally accidentally released as v0.2.0)
