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

  • Disconnect peers which do not respond to requests for headers in a timely manner, to optimise synchronization rate.
  • Dogecoin Core will no longer request further headers from a peer it is already downloading headers from. This stops Dogecoin Core from requesting the same headers more than once, and reduces network bandwidth wasted.
  • Proactively reject block headers which would build on an invalid chain.

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 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.

Minor Changes

  • Corrections to French Canadian, Chinese, German, Indonesian, Korean, Polish and Portuguese translations.
  • Correct a bug that resulted in negative progress per hour being displayed during sync.
  • Regtest network can now generate AuxPoW blocks.
  • Add Snap packaging support.
  • Modify Scrypt code so it's compatible with Alpine Linux's musl library.
  • Update libevent to 2.1.11
  • Update ZMQ to 4.3.4
  • Correctly set fixed seeds on startup.
  • Add build instructions for NixOS.
  • Fix a rare crash bug on shutdown due to ActivateBestChain() being called when there is no best chain.
  • Fix port numbers in contrib/seeds/generate-seeds.py.
