Compatibility
|
||
|
|
==============
|
||
|
|
|
||
|
|
Dogecoin Core is extensively tested on Ubuntu Server LTS, Mac OS X and Windows 10.
|
||
|
|
|
||
|
|
Dogecoin Core should also work on most other Unix-like systems but is not
|
||
|
|
frequently tested on them.
|
||
|
|
|
||
|
|
Notable changes
|
||
|
|
===============

|
|
Enabling Future Fee Reductions
|
||
|
|
-------------------------------
|
||
|
|
|
||
|
|
This release preparing the network for a reduction of the recommended fees by
|
||
|
|
reducing the default fee requirement 1000x for transaction relay and 100x for
|
||
|
|
mining. At the same time it increases freedom for miner, wallet and node
|
||
|
|
operators to agree on fees regardless of defaults coded into the Dogecoin Core
|
||
|
|
software by solidifying fine-grained controls for operators to deviate from
|
||
|
|
built-in defaults.
|
||
|
|
|
||
|
|
This realizes the first part of a two-stage update to lower the fee
|
||
|
|
recommendation.
|
||
|
|
|
||
|
|
The main highlights for these enhancements are:
|
||
|
|
|
||
|
|
* Transaction sizes are no longer rounded up to the nearest kilobyte when
|
||
|
|
deciding if a transaction can be accepted from another node and in applying
|
||
|
|
fee-filter requests from peers, when relaying transactions.
|
||
|
|
* The default setting shipped with dogecoin core for relay fee has been reduced
|
||
|
|
to 0.001 DOGE (was: 1 DOGE). This can be changed by operators using the
|
||
|
|
`-mintxrelayfee=<amount>` option.
|
||
|
|
* Spam management has been delegated to miners, where currently a default fee
|
||
|
|
of 0.01 DOGE has been set as a recommended default, to prevent spam on the
|
||
|
|
blockchain. Miners can change this setting to their liking using the
|
||
|
|
`-blockmintxfee` option.
|
||
|
|
* The relay dust limit has been reduced 100x to 0.01 DOGE and is now
|
||
|
|
configurable via the `-dustlimit` option.
|
||
|
|
|
||
|
|
For this release, the recommended fees and dust limits, as implemented in the
|
||
|
|
wallet, remain at 1 DOGE per kilobyte, inclusive of the rounding up to the
|
||
|
|
nearest kilobyte, as miners and the relay network will upgrade gradually,
|
||
|
|
requiring time for transactions with lower fees to be able to be relayed and
|
||
|
|
mined. Not doing this would result in all transactions being rejected by old
|
||
|
|
nodes. A subsequent release will finalize the second stage and lower the
|
||
|
|
recommended fees implemented in the wallet by default. Wallet operators can
|
||
|
|
however, at their own judgement and convenience, change the fees paid from
|
||
|
|
their wallets with the `-paytxfee=<amount per kb>` option.
|
||
|
|
|
||
|
|
Synchronization Improvements
|
||
|
|
----------------------------
|
||
|
|
|
||
|
|
This release removes a bug in the network layer where a 1.14 node would open
|
||
|
|
many parallel requests for headers to its peers, increasing the total data
|
||
|
|
transferred during initial block download up to 50 times the required data, per
|
||
|
|
peer, unnecessarily. As a result, synchronization has time has been reduced by
|
||
|
|
around 2.5 times.
|
||
|
|
|
||
|
|
Additionally, when a node is in initial synchronization and a peer takes too
|
||
|
|
long to respond to a new header request, it is now aggressively disconnected,
|
||
|
|
to free connection slots for faster peers and not add more stress to already
|
||
|
|
overloaded peers.
|
||
|
|
|
||
|
|
Security enhancements
|
||
|
|
---------------------
|
||
|
|
|
||
|
|
* Proactively disconnect peers sending block headers which would build on an
|
||
|
|
invalid chain.
|
||
|
|
* Improve handling and logging of invalid blocks and their descendants
|
||
|
|
* Fix a bug that was preventing nodes to load a fixed peer list in case DNS
|
||
|
|
services are unreachable.
|
||
|
|
|
||
|
|
GUI Improvements
|
||
|
|
----------------
|
||
|
|
|
||
|
|
* Add menu option to import a private key, "Import Private Key" from the "File"
|
||
|
|
menu.
|
||
|
|
* Improve displayed result when commands in the debug console return null.
|
||
|
|
* Fix text overflow on printed keys and address fields in the paper wallet
|
||
|
|
generator.
|
||
|
|
* Add column to peers table showing bytes sent/received, accessible via
|
||
|
|
"Debug Window" from the "Help" menu.
|
||
|
|
* Add GUI for adding peers manually, accessible from the peers table of the
|
||
|
|
Debug Window.
|
||
|
|
|
||
|
|
RPC Improvements
|
||
|
|
----------------
|
||
|
|
|
||
|
|
`getpeerinfo` now includes `feefilter` value for each peer, to be able to diagnose transaction relay issues.
|
||
|
|
|
||
|
|
