Add notes for 10.2022 update

 Update coincided with persistent state serialization event which lead to block production speed deterioration (issue substantially mitigated in update itself). This phenomena was aggravated by the fact that after update some validators lost ability to participate in block creation. The last was caused by threshold based hardcoded protocol version bump, where threshold was set in such manner (based on block height with value higher than 9m), that it eluded detection in private net tests. The update was temporarily paused and resumed after persistent state serialization ended and issues with block creation were resolved.
 
 Besides the work of the core team, this update is based on the efforts of @awesome-doge (help with abseil-cpp upgrade), @rec00rsiff (noted issues for exotic endianess and implemented network stats) and third-party security auditors.

+## 10.2022 Update
+* Added extended block creation and general perfomance stats gathering
+* Forbidden report data on blocks not committed to the master chain for LS
+* Improved debug in TVM
+* FunC 0.3.0: multi-line asms, bitwise operations for constants, duplication of identical definition for constants and asms now allowed
+* New tonlib methods: sendMessageReturnHash, getTransactionsV2, getMasterchainBlockSignatures, getShardBlockProof, getLibraries.
+* Fixed bugs related to invalid TVM output (c4, c5, libaries) and non-validated network data; avoided too deep recursion in libraries loading
+* Fixed multiple undefined behavior issues
+* Added build of FunC and Fift to WASM
