+## 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).
