## 0.94.0 "Tsessebe" (19 Mar 2021)
|
||||
|
||||
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).
