automatic upgrade code from before version 0.8 to version 0.15.0 or higher. Upgrading

However, as usual, old wallet versions are still supported.

- 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. Support for segwit in those RPCs will continue to be added in future versions.

P2WPKH change outputs are now used by default if any destination in the transaction is a P2WPKH or P2WSH output. This is done to ensure the change output is as indistinguishable from the other outputs as possible in either case.

- Using addresses with the `createmultisig` RPC is now deprecated, and will be removed in a later version. Public keys should be used instead.
- Blockchain rescans now no longer lock the wallet for the entire rescan process, so other RPCs can now be used at the same time (although results of balances / transactions may be incorrect or incomplete until the rescan is complete).
- The `logging` RPC has now been made public rather than hidden.
- An `initialblockdownload` boolean has been added to the `getblockchaininfo` RPC to indicate whether the node is currently in IDB or not.

Testing changes
----------------
- The default regtest JSON-RPC port has been changed to 18443 to avoid conflict with testnet's default of 18332.
- Segwit is now always active in regtest mode by default.
Known Issues
------------
- Occasionally shutting down the Bitcoin Core GUI during the startup and loading phase will cause an assertion error.
- 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.
