+## 0.97.2 "Dissipation" (18 Aug 2021)
+
+We're rolling out an update for NeoGo nodes that mostly concentrates on
+performance. We've tweaked and tuned a lot of code while staying compatible
+with N3 mainnet and testnet. At the same time we're gradually introducing
+changes required for our P2P state exchange extension and this affected DB
+format, so you'll need to resynchronize on update. At the same time, this
+update is not mandatory, 0.97.1 is still perfectly valid for N3 networks.
+
+Note also that we're discussing removal of Badger and Redis databases support
+in future releases, so if you're interested in them take a look at #2130.
+
+Behavior changes:
+ * address blocking in Policy contract now also blocks calls to contracts with
+   blocked addresses (#2132)
+
+Improvements:
+ * numerous memory and CPU optimizations across whole codebase (#2108, #2112,
+   #2117, #2118, #2122, #2123, #2128, #2114, #2133)
+ * preliminary work for P2P state exchange extension (#2119)
+ * `util convert` command now also detects public keys and converts them to
+   script hash/address (#2125)
+
+Bugs fixed:
+ * key decoding functions could accept some additional data even though only
+   key is expected to be present (#2125)
+
 ## 0.97.1 "Gasification" (06 Aug 2021)
 
 We're updating NeoGo to make it compatible with the latest protocol changes
