Dash Core version 0.15
======================

Release is now available from:

  <https://www.dash.org/downloads/#wallets>

This is a new major version release, bringing new features, various bugfixes and other improvements.

Please report bugs using the issue tracker at github:

  <https://github.com/dashpay/dash/issues>


Upgrading and downgrading
=========================

How to Upgrade
--------------

If you are running an older version, shut it down. Wait until it has completely
shut down (which might take a few minutes for older versions), then run the
installer (on Windows) or just copy over /Applications/Dash-Qt (on Mac) or
dashd/dash-qt (on Linux). If you upgrade after DIP0003 activation and you were
using version < 0.13 you will have to reindex (start with -reindex-chainstate
or -reindex) to make sure your wallet has all the new data synced. Upgrading from
version 0.13 should not require any additional actions.

When upgrading from a version prior to 0.14.0.3, the
first startup of Dash Core will run a migration process which can take a few minutes
to finish. After the migration, a downgrade to an older version is only possible with
a reindex (or reindex-chainstate).

Downgrade warning
-----------------

### Downgrade to a version < 0.14.0.3

Downgrading to a version smaller than 0.14.0.3 is not supported anymore due to changes
in the "evodb" database format. If you need to use an older version, you have to perform
a reindex or re-sync the whole chain.

Notable changes
===============

Removal of the p2p alert system
-------------------------------
The p2p alert system was designed to send messages to all nodes supporting it by someone who holds
so called alert keys to notify such nodes in case of severe network issues. This version removes
the `alert` p2p message and `--alert` option. Internal alerts, partition detection warnings and the
`--alertnotify` option features remain.

Removal of the legacy InstantSend system
----------------------------------------
Version 0.14 introduced the new LLMQ-based InstantSend system which is designed to be much more scalable
than the legacy one without sacrificing security. The new system also allows all transactions to be treated as
InstantSend transactions. The legacy system was disabled together with the successful deployment of ChainLocks,
but we had to keep supporting the legacy system for a while to ensure a smooth transition period. This version finally drops
the legacy system completely.

Read more about ChainLocks: https://github.com/dashpay/dips/blob/master/dip-0008.md
Read more about LLMQ-based InstantSend: https://github.com/dashpay/dips/blob/master/dip-0010.md

Sporks
------
The security level of ChainLocks and LLMQ-based InstantSend made sporks `SPORK_5_INSTANTSEND_MAX_VALUE` and
`SPORK_12_RECONSIDER_BLOCKS` obsolete, so they are removed now. Sporks `SPORK_15_DETERMINISTIC_MNS_ENABLED`,
`SPORK_16_INSTANTSEND_AUTOLOCKS` and `SPORK_20_INSTANTSEND_LLMQ_BASED` have no code logic behind them anymore
because they were used as part of the DIP0003, DIP0008 and DIP0010 activation process which is finished now.
They are still kept and relayed only to ensure smooth operation of v0.14 clients and will be removed in some
future version.

Mempool sync improvements
-------------------------
Nodes joining the network will now always try to sync their mempool from other peers via the `mempool` p2p message.
This behaviour can be disabled via the new `--syncmempool` option. Nodes serving such requests will now also push
`inv` p2p messages for InstandSend locks which are held for transactions in their mempool. These two changes
should help new nodes to quickly catchup on start and detect any potential double-spend as soon as possible.
This should also help wallets to slightly improve UX by showing the correct status of unconfirmed transactions
locked via InstandSend, if they were sent while the receiving wallet was offline. Note that bloom-filters
still apply to such `inv` messages, just like they do for transactions and locks that are relayed on a
regular basis.

PrivateSend improvements
------------------------
This version decouples the so called "Lite Mode" and client-side PrivateSend mixing, which allows client-side mixing
on pruned nodes running with `--litemode` option. Such nodes will have to also specify the newly redefined
`--enableprivatesend` option. Non-prunned nodes do not have to do this but they can use `--enableprivatesend`
option to disable mixing completely instead. Please note that specifying this option does not start mixing
automatically anymore (which was the case in previous versions). To automatically start mixing, use the new
`--privatesendautostart` option in addition to `--enableprivatesend`. Additionally, PrivateSend can always be
controlled with the `privatesend` RPC.

Thanks to LLMQ-based InstantSend and its ability to lock chains of unconfirmed transactions (and not only a single
one like in the legacy system), PrivateSend mixing speed has improved significantly. In such an environment
Liquidity Provider Mode, which was introduced a long time ago to support mixing volume, is no longer needed and
is removed now. As such the `--liquidityprovider` option is not available anymore.

Some other improvements were also introduced to speed up mixing, e.g. by joining more queues or dropping potential
malicious mixing participants faster by checking some rules earlier etc. Lots of related code was refactored to
further improve its readability, which should make it easier for someone to re-implement PrivateSend
correctly in other wallets if there is a desire to do so.

Wallet changes
--------------
Wallet internals were optimized to significantly improve performance which should be especially notable for huge
wallets with tens of thousands of transactions or more. The GUI for such wallets should be much more responsive too now.

Running Masternodes from local wallets was deprecated a long time ago and starting from this version we disable
wallet functionality on Masternodes completely.

GUI changes
-----------
The Qt GUI went through a refresh to follow branding color guides and to make it feel lighter. All old themes besides
the Traditional one (the one with a minimal styling) were removed and instead a new Dark theme was added.

In this version we made a lot of optimizations to remove various lags and lockups, the GUI in general should feel
much more smoother now, especially for huge wallets or when navigating through the masternode list. The latter has
a few new columns (collateral, owner and voting addresses) which give more options to filter and/or sort the list.
All issues with hi-dpi monitors should also be fixed now.

The "Send" popup dialog was slightly tweaked to improve the language and provide a bit more information about inputs
included in the transaction, its size and the actual resulting fee rate. It will also show the number of inputs
a PrivateSend transaction is going to consume and display a warning regarding sender privacy if this number is 10
or higher.

Changes in regtest and devnet p2p/rpc ports
-------------------------------------------
Default p2p and rpc ports for devnets and regtest were changed to ensure their consistency and to avoid
any potential interference with bitcoin's regtests. New default p2p/rpc ports for devnet are 19799/19798,
for regtest - 19899/19898 respectively.

ZMQ changes
-----------
Added two new messages `rawchainlocksig` and `rawtxlocksig` which return the raw data of the block/transaction
concatenated with the corresponding `clsig`/`islock` message respectively.

Crash reports and stack traces
------------------------------
Binaries built with Gitian (including all official releases) will from now on always have crash reports and
crash hooks enabled. This means, that all binaries will print some information about the stack trace at the
time of a crash. If no debug information is present at crash time (which is usually the case), the binaries
will print a line that looks like this:
```
2020-01-06 14:41:08 Windows Exception: EXCEPTION_ACCESS_VIOLATION
No debug information available for stacktrace. You should add debug information and then run:
dashd.exe -printcrashinfo=bvcgc43iinzgc43ijfxgm3yba....
```
If you encounter such a crash, include these lines when you report the crash and we will be able to debug it
further. Anyone interested in running the specified `-printcrashinfo` command can do so after copying the debug info
file from the Gitian build to the same place where the binary is located. This will then print a detailed stack
trace.

RPC changes
-----------
There are a few changes in existing RPC interfaces in this release:
- no more `instantsend` field in various RPC commands
- `use-IS`, `use_is` and `instantsend` options are deprecated in various RPC commands and have no effect anymore
- added new `merkleRootQuorums` field in `getblock` RPC results
- individual Dash-specific fields which were used to display soft-fork progress in `getblockchaininfo` are replaced
 with the backported `statistics` object
- `privatesend_balance` field is shown in all related RPC results regardless of the Lite Mode or PrivateSend state

There are also new RPC commands:
- `getbestchainlock`
- `getmerkleblocks`
- `getprivatesendinfo`

`getpoolinfo` was deprecated in favor of `getprivatesendinfo` and no longer returns any data.

There are also new RPC commands backported from Bitcoin Core 0.15:
- `abortrescan`
- `combinerawtransaction`
- `getblockstats`
- `getchaintxstats`
- `listwallets`
- `logging`
- `uptime`

Make sure to check Bitcoin Core 0.15 release notes in a [section](#backports-from-bitcoin-core-015) below
for more RPC changes.

See `help command` in rpc for more info.

Command-line options
--------------------
Changes in existing cmd-line options:
- `--enableprivatesend` option has a new meaning now, see [PrivateSend](#privatesend) section for more info

New cmd-line options:
- `--printcrashinfo`
- `--syncmempool`
- `--privatesendautostart`

Few cmd-line options are no longer supported:
- `--alerts`
- `--masternode`, deprecated, specifying `--masternodeblsprivkey` option alone is enough to enable masternode mode now
- `--liquidityprovider`
- `--enableinstantsend`, dropped due to removal of the Legacy InstantSend

Make sure to check Bitcoin Core 0.15 release notes in a [section](#backports-from-bitcoin-core-015) below
for more changes in command-line options.

See `Help -> Command-line options` in Qt wallet or `dashd --help` for more info.

Build system
------------
This version always includes stacktraces in binaries now, `--enable-stacktraces` option is no longer available.
Instead you can choose if you want to hook crash reporting into various types of crashes by using `--enable-crash-hooks`
option (default is `no`). When using this option on macOS make sure to build binaries with `make -C src osx_debug`.

Backports from Bitcoin Core 0.15
--------------------------------

Most of the changes between Bitcoin Core 0.14 and Bitcoin Core 0.15 have been backported into Dash Core 0.15.
We only excluded backports which do not align with Dash, like SegWit or RBF related changes.

You can read about changes brought by backporting from Bitcoin Core 0.15 in following docs:
- https://github.com/bitcoin/bitcoin/blob/master/doc/release-notes/release-notes-0.15.0.md
- https://github.com/bitcoin/bitcoin/blob/master/doc/release-notes/release-notes-0.15.1.md

Some other individual PRs were backported from versions 0.16+, you can find the full list of backported PRs
and additional fixes in https://github.com/dashpay/dash/blob/master/doc/release-notes/dash/release-notes-0.15-backports.md

Miscellaneous
-------------
A lot of refactoring, backports, code cleanups and other small fixes were done in this release. Dash-specific
modules were reorganized in separate folders to make navigation through code a bit easier.
