Raw Blame History

Dogecoin Core version 1.14.5 is now available from:

https://github.com/dogecoin/dogecoin/releases/tag/v1.14.5/

This is a new minor version release, including various bugfixes and performance improvements. It is a recommended update for all users.

Please report bugs using the issue tracker at github:

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

Fee Reductions

This release reduces the recommended fees, following reduction of the required fees in 1.14.4. The main highlights for the revised fee schedule are:

  • The user interface for selecting fees when sending Dogecoins has been updated to give an idea of how much is being spent, rather than a block target. As Dogecoin blocks are not full, typically all transactions are mined in the next block, and therefore the target estimation does not makes sense for Dogecoin.
  • Transaction sizes are no longer rounded up to the nearest kilobyte before calculating fees, which significantly simplifies fee calculation logic. It is anticipated this will also simplify fee calculation by third party wallets which typically use Bitcoin-like fee calculation.
  • The default transaction fee is now 0.001 DOGE per kilobyte, although note you may see transactions take 2-3 blocks to be confirmed while using low fees, until miners update.
  • Tune defaults for replace by fee values, with default DEFAULT_INCREMENTAL_RELAY_FEE now 0.0001 DOGE/kb.
  • Derive minimum change from configurable parameters -discardthreshold and -mintxfee as a basis. Specifically: min change = discardThreshold + 2 * minTxFee(1000)
  • Introduce -harddustlimit, which is used for testing standard transactions. The existing dust limit (-dustlimit) is now enforcing the economic disincentive under which each output under the limit must add additional fee to be accepted to the mempool.
  • Introduce -discardthreshold, a wallet-specific, configurable dust limit that enables gradual implementation of the dust limit. Each transaction created with the wallet will adhere to this threshold rather than the dust limits used for relay, so that the wallet stays usable while the network changes (lowers) its dust limits.
  • Add dustlimit info to getnetworkinfo RPC command, as it is now configurable.

BDB Updated to 5.3

The Berkley DB version used by Dogecoin Core has been updated to 5.3 (from 5.1) as 5.3 is now standard on many Linux distributions. In testing 5.1 and 5.3 files appear readily interchangeable, although we would recommend not attempting to open wallets from Dogecoin Core 1.14.5 in previous versions of Dogecoin Core, as a precautionary measure.

Key Derivation

The BIP32 hierarchical deterministic key derivation path contained the wrong chain ID. Previously the chain ID 0 was used, it's now correctly set to 3 as per SLIP44.

This has a relatively minimal impact currently, however in future versions where expect more use of hierarchical deterministic keys, this is important to define consistently. In particular it is important that the key derivation paths used by Dogecoin Core and hardware wallets are consistent, so that extended keys from one can be used with the other. This will also simplify future compatibility with projects such as HWI, which could enable Dogecoin Core to use hardware wallets.

Version UI

Dogecoin version is now displayed in the bottom-left of the window, rather than in the Dogecoin logo in the wallet window. This means it is updated automatically, rather than requiring manual work editing the image.

createauxblock/submitauxblock

The createauxblock and submitauxblock commands have been introduced, mimicking the same commands from Namecoin 0.17+. These progress towards splitting the consensus layer from the wallet (getauxblock generates an address to mine to, while the new createauxblock command takes in an address to mine to, and therefore does not require the wallet). It also enables mining pools to use multiple wallet addresses if desired.

By default createauxblock provides difficulty target in a field called target, however this can be tweaked for Namecoin-like API ("_target") by setting the -rpcnamecoinapi startup argument.

Minor Changes

  • Fix compilation on FreeBSD, which was failing to compile the Scrypt code.
  • Refresh FreeBSD docs, see doc/build-freebsd.md.
  • Update to OpenSSL 1.0.2u.
  • Refresh translation files to simplify volunteer contributions to translations.
  • Remove export of glibc 2.17 secure_getenv to fix glibc minimum required.
  • Add xkbcommon 0.8.4 to fix keyboard compatibility issues.
  • Address compatibility issues with GCC-7 and glibc-2.27.
  • Remove legacy patches which are no longer needed due to test environments being updated to more recent Ubuntu releases.
  • Security harden systemd unit file contrib/init/dogecoind.local.service.
  • Make Freetype library version independent from build system libaries.
  • Update Univalue library to 1.0.4.
  • Correct block download timeout for regtest, where it was too low and causing issues with tests.
  • Experimental build for SHA algorithms with AVX2 support, to improve SHA performance.
