v0.94.0
a727ba7

N3 RC1-compatible release is here. We've implemented all Neo protocol changes (including state validation service and NeoFS support for oracles) and are ready for testnet launch now, so that you could play with new native contracts, VM instructions and other goodies RC1 brings with it. Some usability improvements and documentation updates also went into this release as well as a number of fixes stabilizing Notary subsystem (which is NeoGo-specific protocol extension).

Please note that this release is incompatible with 0.93.0. We do plan to make an update soon (with more examples and documentation), but there won't be long-term support provided, Neo N3 is still on its way to mainnet (although RC1 and testnet are major milestones on this route).

  • wallet multisign sign command was renamed to wallet sign, it now works not just for multisignature contract signing, but also for multiple regular signers as well as contract verification signing
  • conversion interops were moved to StdLib native contract (#1824)

Improvements:

  • verification script are now allowed to make contract calls (#1751)
