v0.71.0

Version 0.71.0 ends the year 2019 of neo-go development with a solid release
that adds support for pprof, implements all missing interoperability
functions, improves performance and as usual fixes some bugs. This is also the
first release with a test coverage of more than 60% which is a significant
milestone in our trend to improve code quality and testing. Back in August
2019 when NSPCC had started neo-go developement the project only had a
coverage of 45% and even though a lot of code has been added since we're
improving this metrics with every release.

New features:

  • pprof support (disabled by default, #536)
  • compiler now supports assignments to an element of slice using variable
    index (#564)
  • hashed 4-byte IDs support for SYSCALL instruction (#565)
  • remainder ('%') operator support in compiler (#563)
  • Neo.Witness.GetVerificationScript and Neo.InvocationTransaction.GetScript
    interop functions (#421)
  • Neo.Iterator., Neo.Enumerator. and Neo.Storage.Find interops (#422)
  • tuple return support in compiler (#562)
  • getblocks P2P command implementation (#577)

Behaviour changes:

  • db dump command now also writes the block number zero by default to
    comply with ImportBlocks format (#582)
  • skip parameter was renamed to start in the db dump command (#582)
  • db restore now skips the genesis block in the dump if starting to import
    into the new DB and if this block matches the one generated on blockchain
    init (#582)

Improvements:

  • VM optimizations (#558, #559, #565, #572)
  • top block caching in core to improve dApps performance (#572)
  • transaction's TXType can now be JSON-unmarshalled (#575)
  • crypto package no longer exports AES functions (#579)
  • merkle tree functions and structures were moved into the hash package
    (#579)
  • base58 functionality was moved into its own package from crypto (#579)
  • Uint160DecodeAddress and AddressFromUint160 functions were moved out of
    crypto into their own package (#579)
  • address package now can be configured to use different prefixes (#579)

Bugs fixed:

  • wrong INVERT instruction behaviour for converted values (#561)
  • wrong DUP behaviour when the next instruction doesn't convert the value
    (#561)
  • OVER and PICK implementations didn't properly duplicate stack items (#561)
  • PICKITEM instruction failed to duplicate picked items (#561)
  • getblock RPC call was not answering with full hex-encoded block (#575)
  • base58.CheckDecode was decoding values with leading zeroes in a wrong way
    (#579)
  • decoding wrong public key could succeed (#579)
  • consensus payload verification was inconsistent with other verification
    code (#555)
  • DB dump was using wrong format in release 0.70.1 (#582)
  • DB restorer was not properly counting skipped blocks which could lead to
    bogus error being reported (#582)
  • the DB was not closed properly on error during DB restore (#582)
  • NPE in consensus (#583)
