 - All segwit keys in the wallet get an implicit redeemscript added, without it being written to the file. This means recovery of an old backup will work, as long as you use new software.
 - All keypool keys that are seen used in transactions explicitly get their redeemscripts added to the wallet files. This means that downgrading after recovering from a backup that includes a segwit address will work
 
-Note that some RPCs do not yet support segwit addresses. Notably, `signmessage`/`verifymessage` doesn't support segwit addresses, nor does `importmulti` at this time. `dumpwallet`/`importwallet` work, but will (in comments) list the corresponding P2PKH addresses for all keys, even those only used in segwit addresses.

 - Using addresses with the `createmultisig` RPC is now deprecated, and will be removed in a later version. Public keys should be used instead.

+- Segwit is now always active in regtest mode by default. Thus, if you upgrade a regtest node you will need to either -reindex or use the old rules by adding `vbparams=segwit:0:999999999999` to your regtest bitcoin.conf. Failure to do this will result in a CheckBlockIndex() assertion failure that will look like: Assertion `(pindexFirstNeverProcessed != nullptr) == (pindex->nChainTx == 0)' failed.
