- [`BIP 155`](https://github.com/bitcoin/bips/blob/master/bip-0155.mediawiki): The 'addrv2' and 'sendaddrv2' messages which enable relay of Tor V3 addresses (and other networks).
- [`BIP 158`](https://github.com/bitcoin/bips/blob/master/bip-0158.mediawiki): Compact Block Filters for Light Clients.
KeePass support removed
-----------------------
Please make sure to move your coins to a wallet with a regular passphrase.
Wallet changes
--------------
We continued backporting wallet functionality updates. Most notable changes
are:
- Added support for empty, encrypted-on-creation and watch-only wallets.
- Wallets can now be created, opened and closed via a GUI menu.
- No more `salvagewallet` option in cmd-line and Repair tab in GUI. Check the
`salvage` command in the `dash-wallet` tool.
Indexes
-------
The transaction index is moved into `indexes/` folder. The migration of the old
data is done on the first run and does not require reindexing. Note that the data
in the old path is removed which means that this change is not backwards
compatible and you'll have to reindex the whole blockchain if you decide to
downgrade to a pre-v18.0.0 version.
Remote Procedure Call (RPC) Changes
-----------------------------------
Most changes here were introduced through Bitcoin backports mostly related to
the deprecation of wallet accounts in DashCore v0.17 and introduction of PSBT
format.
The new RPCs are:
-`combinepsbt`
-`converttopsbt`
-`createpsbt`
-`decodepsbt`
-`deriveaddresses`
-`finalizepsbt`
-`getblockfilter`
-`getdescriptorinfo`
-`getnodeaddresses`
-`getrpcinfo`
-`joinpsbts`
-`listwalletdir`
-`quorum rotationinfo`
-`scantxoutset`
-`submitheader`
-`testmempoolaccept`
-`utxoupdatepsbt`
-`walletcreatefundedpsbt`
-`walletprocesspsbt`
The removed RPCs are:
-`estimatefee`
-`getinfo`
-`getreceivedbyaccount`
-`keepass`
-`listaccounts`
-`listreceivedbyaccount`
-`move`
-`resendwallettransactions`
-`sendfrom`
-`signrawtransaction`
Changes in existing RPCs introduced through bitcoin backports:
- The `testnet` field in `dash-cli -getinfo` has been renamed to `chain` and
now returns the current network name as defined in BIP70 (main, test, regtest).
- Added `window_final_block_height` in `getchaintxstats`
- Added `feerate_percentiles` object with feerates at the 10th, 25th, 50th,
75th, and 90th percentile weight unit instead of `medianfeerate` in
`getblockstats`
- In `getmempoolancestors`, `getmempooldescendants`, `getmempoolentry` and
`getrawmempool` RPCs, to be consistent with the returned value and other RPCs
such as `getrawtransaction`, `vsize` has been added and `size` is now
deprecated. `size` will only be returned if `dashd` is started with
`-deprecatedrpc=size`.
- Added `loaded` in mempool related RPCs indicates whether the mempool is fully
loaded or not
- Added `localservicesnames` in `getnetworkinfo` list the services the node
offers to the network, in human-readable form (in addition to an already
existing `localservices` hex string)
- Added `hwm` in `getzmqnotifications`
-`createwallet` can create blank, encrypted or watch-only wallets now.
- Added `private_keys_enabled` in `getwalletinfo`
- Added `solvable`, `desc`, `ischange` and `hdmasterfingerprint` in `getaddressinfo`
- Added `desc` in `listunspent`
Dash-specific changes in existing RPCs:
- Added `quorumIndex` in `quorum getinfo` and `quorum memberof`
- In rpc `masternodelist` with parameters `full`, `info` and `json` the PoS penalty score of the MN will be returned. For `json` parameter, the field `pospenaltyscore` was added.
Please check `help <command>` for more detailed information on specific RPCs.
