0.11.2 Release notes
|
|
====================
|
|
|
|
Dash Core version 0.11.2 is now available from:
|
|
|
|
https://dashpay.io/downloads
|
|
|
|
Please report bugs using the issue tracker at github:

|
Masternode enhancements
|
|
-----------------------
|
|
|
|
When restarting the client the masternodes will be stored in the datadir in
|
|
*mncache.dat* file (make sure you don't have any wallet with such name or this
|
|
functionality will not be available for you)
|
|
|
|
|
|
Mining and relay policy enhancements
|
|
------------------------------------
|
|
|
|
Dash Core's block templates are now for version 3 blocks only, and any
|
|
mining software relying on its `getblocktemplate` must be updated in parallel
|
|
to use libblkmaker either version 0.4.2 or any version from 0.5.1 onward. If you
|
|
are solo mining, this will affect you the moment you upgrade Dash Core,
|
|
which must be done prior to BIP66 achieving its 951/1001 status. If you are
|
|
mining with the stratum mining protocol: this does not affect you. If you are
|
|
mining with the getblocktemplate protocol to a pool: this will affect you at the
|
|
pool operator's discretion, which must be no later than BIP66 achieving its
|
|
951/1001 status.

|
|
BIP 66: strict DER encoding for signatures
|
|
------------------------------------------
|
|
|
|
Dash Core 0.11.2 implements BIP 66, which introduces block version 3, and a
|
|
new consensus rule, which prohibits non-DER signatures. Such transactions have
|
|
been non-standard since Dash 0.8, but were technically still permitted
|
|
inside blocks.
|
|
|
|
This change breaks the dependency on OpenSSL's signature parsing, and is
|
|
required if implementations would want to remove all of OpenSSL from the
|
|
consensus code.
|
|
|
|
The same miner-voting mechanism as in BIP 34 is used: when 751 out of a
|
|
sequence of 1001 blocks have version number 3 or higher, the new consensus
|
|
rule becomes active for those blocks. When 951 out of a sequence of 1001
|
|
blocks have version number 3 or higher, it becomes mandatory for all blocks.
|
|
|
|
Backward compatibility with current mining software is NOT provided, thus
|
|
miners should read the first paragraph of "Mining and relay policy
|
|
enhancements" above.
|
|
|

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).
