BitShares Core Release 2.0.181120

The BitShares community discovered a problem in the UI introduced by a change in bitshares-core in the 2.0.181105 release. The voting page of the UI was blank, caused by the removal of the budget_object in PR 1213.

This release reverts just that change, and allows the voting page to be displayed correctly.

No upgrade is required by any operator of a validation node. Yet operators of API nodes should upgrade to this release. Users of the BitShares UI will benefit when the node they connect to has been upgraded.

BitShares Core Release 2.0.181105

The BitShares Core software has been updated to the 201810 Feature Release. The Core software is used by validation nodes which perform consensus of all transactions on the BitShares blockchain. This release includes new features, optimizations, and bug fixes but does not include any changes to the consensus protocol.

No action is required if you do not operate a validation node or the command line interface (CLI) wallet.

Numerous performance improvements have been made to the software that will benefit all operators of validation nodes including block producers, seed nodes, and API nodes, especially those using the Elasticsearch plugin.

Documentation for BitShares developers may be now be found at the new BitShares Developer Portal (https://dev.bitshares.works).

Who Should Upgrade?

No upgrade is required by any operator of a validation node. Yet many operators will benefit by upgrading.

All operators will benefit from performance improvements (915, 1327, 1359) and fixes (1024, 1203, 1286, 1325).

Operators of block producing nodes will benefit from performance improvements (1251), safety measures (1252), and fixes (1266, 1332, 1364).

Operators of API nodes including Elasticsearch APIs will benefit from improvements to data availability (1351, 1352) and performance (1049, 1271, 1356).

Users of the command line interface (CLI) wallet will also benefit from improvements (1195, 1248).

Upgrade Process

Precautions

Precaution 1

Operators of API nodes that service client software that expect to receive updates about all data on the blockchain by default (such as BitShares Reference Wallet before 180401), as opposed to narrowly subscribed data, should ensure that their API nodes are configured with the enable-subscribe-to-all set to true due to Pull Request 1049.

How to Upgrade from Source Code

BitShares Core Release 2.0.180612

This is a protocol upgrade release. All nodes should upgrade before 2018-07-19 14:00:00 UTC.

Note: in the previous release (2.0.180425) we fixed a serious bug.

  • If you're upgrading from 2.0.180425 to 2.0.180612, you don't need to do anything special;
  • if you're upgrading from a release earlier than 2.0.180425 to 2.0.180612, please check release notes of 2.0.180425 to see if you need to perform additional steps.

Consensus changes

API changes

  • extensions field of call_order_update_operation changed from an array to an object, which affects all related API's E.G. get_block, get_account_history, get_relative_account_history and etc. Due to this, old version of cli_wallet won't be compatible with new API nodes when that operation would occur in result.
  • [Issue #862, PR #872] Improved pagination of list_assets node API
  • [Issue #863, PR #871] Node get_ticker API now returns time stamp of latest block instead of server time
  • [Issue #811, PR #861] Added get_full_account command/API to cli_wallet

BitShares Core Release 2.0.180425

This is a bugfix release.

In this release we fixed a bug in account history plugin, which may result in incorrect operation history IDs being stored under certain circumtances. Account history is mainly used by 3rd-party businesses for integration.

This bug doesn't affect consensus or chain security.

Who need to upgrade, and what to do

Businesses (E.G. exchanges, payment processors, gateways or merchants) who're running witness_node with track-account option, if rely on correctness of operation history object IDs (1.11.x) returned by witness_node to identify transactions, are likely affected.

Please:

  1. upgrade the node, and
  2. restart the node with --replay-blockchain parameter, and
  3. carefully check historical data which was retrieved from the old node and processed in the past, compare it to new data returned by upgraded node, deal with the differences if needed, and
  4. perhaps review business data process logic.

Please be aware that the 3rd step is important for businesses to avoid processing same transaction (E.G. a deposit) more than once. After restarted with --replay-blockchain, history object IDs may have changed. For example, before restart, get_relative_account_history [account_name] 0 1 0 may return an operation history ID 1.11.123456789 which indicates a deposit, but after restart, operation history ID of the same deposit may have changed to 1.11.123456700.

All earlier versions are affected.

Who are not affected

Here are some cases likely not affected by the bug. However, for your own safety, please make decision by your own.

  • The bug doesn't affect delayed_node, so data stored and returned by delayed_node is always correct. IDs stored in witness_node can be different than those stored in delayed_node. If a business only reads data from delayed_node, it's not affected.

    • However, if the business also reads data from witness_node, it can be affected.

  • Businesses that don't rely on correctness of 1.11.x IDs to identify transactions, for example those identify transactions by transaction IDs or signatures, are likely not affected, so don't need to upgrade.

  • Nodes that were not running with track-account option are not affected, so no need to upgrade.

    • Nodes running with default options are in this categary.
    • Public seed nodes, API nodes and witnesses should be in this categary.

  • Personal nodes that are not interested in history object IDs are probably affected, but usually don't need to upgrade.

More info about the bug

The bug was in account history plugin, if track-account option is used in a node, when forking occurs (E.G. due to network latency issues), the node may unintendedly skip some IDs. After that, incorrect IDs will be stored and then be returned when being queried. A restart with --replay-blockchain may correct IDs of existing/historical data, but doesn't prevent new incorrect IDs from being stored.

After upgraded and replayed, the node won't skip IDs, so will always store correct IDs.

Related issue and pull request: #585, #873.

BitShares Core Release 2.0.180328

This release contains several security fixes. All nodes please upgrade as soon as possible.

git fetch origin
git checkout 2.0.180328
git submodule update --init --recursive # this command will fail
git submodule sync --recursive
git submodule update --init --recursive

Security fixes

New features and improvements

  • Implemented grouped_order plugin with API, enabled by default in witness_node, so clients can get cleaner order book when there are lots of dust orders: #639, #662

BitShares Core Release 2.0.171212

After the hardfork release (2.0.171105a) and hardfork date (2017-12-08) passed, the BitShares Core dev team has enough updates for a new release. This release targets API nodes and we recommend them to upgrade. Block producers (witnesses) and seed nodes should keep in the hardfork release (2.0.171105a) until we can confirm the new release is stable enough.

The most notorious changes are in the addition and update of plugins and some general fixes. No consensus changes are present in this release and the upgrade is recommended to API nodes but optional.

Changes

  • New ElasticSearch plugin. Pull request: #444 - Allows to run full nodes with reduced RAM while it adds more robust querying into account history. Issues: #358 #503 #413 #373 #430 #487

    • libcurl-dev is now a dependency (sudo apt-get install libcurl4-openssl-dev).

  • Market History plugin changes. Several improvments were done in this release to the market history plugin. Related pull requests: #455 #478 #513 #466 Issues: #449 #472 #467 #454 #448 #505 #509 #185 #521 #465

  • Now supports boost 1.61, 1.62 and 1.63: #483 #486

UPDATE (2017-11-07): Please use 2.0.171105a. Consensus upgrade is scheduled at 2017-12-08 15:40:00 UTC.

UPDATE (2017-11-03): Don't upgrade to this release. It won't sync further than block #21462208. We've found the reason, will release a new version soon. Before the fix is out, block producing nodes (witnesses) and seed nodes please use 2.0.171019a, other nodes please use 2.0.170710 or 2.0.171019a.

This release merges all the work done in the last 3 months in the develop Bitshares branch into master.

All full nodes must upgrade before 2017-11-27 14:40:00 UTC!
