Dogecoin Core version 1.14.7 is now available from:

https://github.com/dogecoin/dogecoin/releases/tag/v1.14.7/

This is a new minor version release, including enchancements to several RPC methods and important security updates for Dogecoin-Qt. Dogecoin-Qt users on any platform are strongly recommended to upgrade.

Please report bugs using the issue tracker at GitHub:

https://github.com/dogecoin/dogecoin/issues

To receive notifications about updates, subscribe to the release mailing list:

Compatibility

Dogecoin Core is extensively tested on Ubuntu Server LTS, macOS and Windows. Minimum OS compatibility can be found in the INSTALL guide.

Notable changes

Important Security Updates

This release contains fixes for Dogecoin Qt across all platforms that increase security for end users.

Disable BIP-70 payment server by default

To mitigate future potential risk inside Dogecoin Qt, support for BIP-70 payment requests and related BIP-71 and BIP-72 payment URIs and MIME types have been disabled by default, because this functionality interacts with remote websites in an automated manner and could be used to amplify any future vulnerabilities inside Dogecoin Qt. By default, incoming BIP-70 payment requests and files or URLs that use the functionality are rejected and an explanation is shown to the user.

BIP-21 payment requests remain fully supported.

The functionality can be re-enabled by using enable-bip70=1 either in your dogecoin.conf or as an argument to Dogecoin-Qt if absolutely needed. Please use extreme caution when exercising this option.

This is step 1 in full deprecation of BIP-70, BIP-71 and BIP-72 inside Dogecoin Core. Future releases may completely remove this feature.

Implemented with #3412

Other security-related fixes

  • Reduce the build scope of the Qt dependency to only include those features we use, to not package potential vulnerabilities. Also stop using libX11 features outside of libxcb (#3358)
  • Backport patches for all Qt versions until 5.15.12 + community patches to the pinned Qt 5.7.1, because we cannot update that due to backward compatibility guarantees (#3415)
  • Added security guidance to INSTALL.md and build guides, to remind those that self-compile to update their system libraries. (#3384)
  • Updated the rpcuser.py script to improve the password and salt generation methods it uses (#3388). If you've used this script in the past, replacing current authentication in dogecoin.conf with new credentials generated with the new version of this script is recommended.

Maintain RPC fee estimation facilities

Fee estimation was explicitly not ported or supported on Dogecoin Core since 1.14.0, but as the non-functional data from estimatefee and estimatesmartfee were anyway used in the field, services using these RPC methods were unable to provide fee estimates to their users. Therefore this feature has now been ported to support Dogecoin parametrization.

The RPC methods estimatefee and estimatesmartfee are now under active maintenance and will be further enhanced in the future.

NOTE: Because the minimum and maximum tracked fees and spacing of fee buckets has changed, the fee_estimates.dat file from earlier versions will be discarded after restarting this version of the software. This means that after the first restart, the estimates will reset, but become usable again after the node has processed a few blocks, and will improve in precision over up to 12 hours after the first restart. Any subsequent restarts will use the estimates from the file as usual.

If you have in the past ran a custom compiled version of 1.14.7 or created your own higher version, you must manually delete the fee_estimates.dat file from your datadir for the new parametrization to take full effect.

Implemented with #3389 and #3433

Add fully verbose transaction decoding to getblock

Updates the getblock RPC to use verbosity levels 0-2 besides the existing boolean. This allows operators to decode a full block in one go when using level 2, instead of having to query getrawtransaction for each individual txid returned with the boolean true.

Mapping between boolean and integer parameter functionality:

Verbosity boolean level (int)
Hex encoded block false 0
Block with txids true 1
Block with decoded transactions - 2

For more information see:

dogecoin-cli help getblock

Implemented with #3299, #3306 and #3307

Features

Add the getblockstats RPC method

The new getblockstats RPC method computes statistics for a given block hash if the block is available on the node (pruned nodes can only run statistics over blocks that aren't pruned.)

The user can select which stats are returned to save processing time for stats that aren't wanted. For more information, use:

dogecoin-cli help getblockstats

Implemented with #3297

Add a height parameter to -walletnotify

Adds %i in the command to include the height of the block containing the transaction. If the transaction is not in any block, the height is 0.

Implemented with #3257 and #3382

Translation Updates

Updates have been provided to the following languages:

  • Chinese (#3103, #3419)
  • Dutch (#3435)
  • French (#3148, #3195)
  • French-Canadian (#3441)
  • Italian (#3428)
  • Korean (#3395, #3430)
  • Polish (#3431)

RPC API Changes

  • Added getblockstats (#3297)
  • Allowed verbosity to be expressed as an integer to getblock and add full verbosity under level 2 that serializes all transactions as JSON in the reply (#3299, #3306, #3307)
  • Added a height parameter to importpubkey (#3102) and importaddress (#3235) which allows the user to specify from which chain height to rescan for wallet transactions.
  • Added getmocktime (regtest-only) (#3322)
  • Added documentation for RPC method maturity in rpc-maturity.md (#3443)

Dependency Updates

  • Updated the depends, CI and build system to Ubuntu Focal (#3143, #3144, #3145, #3222)
  • Updated expat to version 2.5.0 (#3271)
  • Updated the secp256k1 subtree to 44c2452 (#3082, #3142)
  • Updated zlib to version 1.3 (#3345)
  • Updated protobuf to version 3.6.1 (#3357)
  • Updated fontconfig to version 2.12.6 (#3364)
  • Updated the experimental intel-ipsec-mb dependency to version 1.2, adds AVX2 support for Windows x86_64 (#3071, #3146, #3214)

NOTE: on systems that cannot use pinned dependencies from depends/, please be aware that due to a bug in boost-1.83, building may lead to failure. More information about the bug can be found at the boostorg/signals GitHub repository at boostorg/signals2#68.

Bug Fixes

  • Fixed a bug where -maxtxfee was not being respected outside of the wallet, which caused problems with the sendrawtransaction RPC call. (#3088)
  • Fixed the example dogecoind.service file (#3066)
  • Fixed a bug where misnamed signal handlers were causing excessive warnings in Dogecoin Qt logs (#3063)
  • Fixed a bug where extremely long wallet labels could cause Qt popups to flow over screen limits, causing the user to have no means of accepting or rejecting the transaction (#3224)
  • Fixed an interaction error where running Qt tests interacted with the mainnet datadir (#3286)
  • Fixed a bug that caused qt4 compilation to fail (#3427)

Minor Changes

  • Enforced explicit enabling of experimental features by introducing a build flag (--enable-experimental) and enforce these at compile time (#3136). See experiments.md for more information about which experiments are available to self-compile.
  • Re-enabled Scrypt SSE2 routines and encapsulated it as an experimental feature to help speeding up PoW verification on x86_64 architecture. (#2773)
  • Packaged the Noto Sans font to make sure all languages can be rendered (#2676)
  • Updated assumevalid to help new nodes save CPU time by setting it to block e7d4577405223918491477db725a393bcfc349d8ee63b0a4fde23cbfbfd81dea, at height 5,050,000 on mainnet (#3416)
  • Enhanced the paper wallet print function to default to the User's paper format instead of A4 (#3239)

  • Added a translation in Vietnamese (#3060), and fixed missing information in the Chinese README translations (#3070)
  • Updated the python ltc-scrypt module to a maintained fork (#3080), which can be found at https://github.com/dogecoin/ltc-scrypt
  • Backported a pure Python implementation of RIPEMD160 from Bitcoin Core (#3081)
  • Removed historical OpenSSL comparison tests to increase compatibility with OpenSSL 3+ (#3079)
