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).
|
|
|
|
Downgrade warning
|
|
-----------------
|
|
|
|
### Downgrade to a version < 0.12.2.2
|
|
|
|
Because release 0.12.2.2 included the [per-UTXO fix](release-notes/dash/release-notes-0.12.2.2.md#per-utxo-fix)
|
|
which changed the structure of the internal database, you will have to reindex
|
|
the database if you decide to use any pre-0.12.2.2 version.
|
|
|
|
Wallet forward or backward compatibility was not affected.
|
|
|
|
### Downgrade to 0.12.2.2
|
|
|
|
Downgrading to 0.12.2.2 does not require any additional actions, should be
|
|
fully compatible.
|
|
|
|
Notable changes
|
|
===============
|
|
|
|
InstantSend fixes
|
|
-----------------
|
|
|
|
Coin selection could work slightly incorrect in some edge cases which could
|
|
lead to a creation of an InstantSend transaction which only the local wallet
|
|
would consider to be a good candidate for a lock. Such txes was not locked by
|
|
the network but they were creating a confusion on the user side giving an
|
|
impression of a slightly higher InstantSend failure rate.
|
|
|
|
Another issue fixed in this release is that masternodes could vote for a tx
|
|
that is not going to be accepted to the mempool sometimes. This could lead to
|
|
a situation when user funds would be locked even though InstantSend transaction
|
|
would not show up on the receiving side.
|
|
|
|
Fix -liquidityprovider option
|
|
-----------------------------
|
|
|
|
Turned out that liquidityprovider mixing mode practically stopped working after
|
|
recent improvements in the PrivateSend mixing algorithm due to a suboptimal
|
|
looping which occurs only in this mode (due to a huge number of rounds). To fix
|
|
the issue a small part of the mixing algorithm was reverted to a pre-0.12.2 one
|
|
for this mode only. Regular users were not affected by the issue in any way and
|
|
will continue to use the improved one just like before.
|
|
|
|
Other improvements and bug fixes
|
|
--------------------------------
|
|
|
|
This release also fixes a few crashes and compatibility issues.
