Releases: bnb-chain/bsc
v1.1.10
This is a hardfork release that will enable BEP127 and BEP131 on the Chapel testnet. This upgrade is named after Leonhard Euler in honor of his key contributions to mathematics and mechanics. The current block generation speed forecasts this to occur around May 11th at 03:18:00 AM (UTC). The validators and full node operators on testnet should switch their software version to this release by May 11th.
Upcoming Changes
BEP-127 Temporary Maintenance Mode for Validators
Due to the design of Parlia consensus, the absence of the validator, even if it is due to scheduled maintenance, will cause instability and capacity loss of BSC due to the extra waiting time and chain reorganization for other validators. Introducing Temporary Maintenance mode will stabilize the blocking rotation and maintain the capacity of BSC.
A validator can claim itself to enter temporary maintenance mode by sending a transaction to interact with ValidatorSet smart contract. Temporary maintenance is supposed to last one or a few hours. The validator seat will be temporarily dropped from the block producing rotation during the maintenance. Since long-time offline maintenance is not encouraged, the validator will still be slashed if the maintenance lasts too long. To lower the impact from poorly-operating validators who forget to claim its maintenance, they will be forced to enter temporary maintenance mode too.
Check BEP-127 for more details.
BEP-131 Introduce candidate validators onto BNB Smart Chain
This BEP introduces candidate validators onto BSC testnet to improve the liveness and robustness of the network.
BSC testnet will introduce more validators, e.g. another 10 inactive validators, into the validator set as backups, which will be called "Candidates". Candidates will produce blocks and charge gas fees on BNB Smart Chain mainnet, but with a much less chance than the active validator set of 11 elected. A decent motivation is expected to be maintained so that the candidate validators are willing to ensure the quality and help secure BNB Smart Chain.
The number of Candidate Validators is subjected to the BSC testnet governance. The BSC Chapel Testnet will keep the same number of Active Validators and 0 Candidate Validators right after Euler upgrade, and the later governance action will enlarge the Candidate Validator Set to allow new Candidate Validator to be set up.
Check BEP-131 for more details.

v1.1.8
Description
Release v1.1.8 is a performance release. Verification && Commit Pipeline, Go Native Tracer and Block Prune are introduced in this release.
Change log
FEATURES
- #668 implement State Verification && Snapshot Commit pipeline
- #581 implement geth native trace
- #543 implement offline block prune tools
IMPROVEMENT
- #704 prefetch state by applying the transactions within one block
- #713 add ARM binaries for release pipeline
BUGFIX

Changes
State Verification && Commit Pipeline
State verification and storage commit pipeline is introduced in #668. It is an experimental feature that is expected to improve the performance, enable it by appending --pipecommit to the process command.
Ancient Data Prune
A new tool is introduced to prune ancient undesired block data, it will discard block, receipt, header in the ancient db to save space.
Example: ./geth snapshot prune-block --datadir ./node --datadir.ancient ./chaindata/ancient --block-amount-reserved 1024.
Note: 1. Stop the client before pruing; 2. datadir.ancient is based on datadir, ./chaindata/ancient means ${datadir}/geth/chaindata/ancient actually
Go Native Tracer
The default tracer is now based Golang implementation rather than Js implementation.

v1.1.7
This is a hot fix release for a syncing issue during diffsync, check #628 for more details. All clients are suggested to upgrade.
If you come across with Bad Block error with a log message like: expected tx hash xx, get xx, nonce xx, to xx, value xx, gas xx, gasPrice xx, data xx. Following is the guide to recover the node:
- Stop The node.
- Upgrade the binary to the latest release.
- Start the node with
--snapshot=false - Wait for a few minutes(it depends on how fast the node is), until the block height is 128 higher than where it stopped.
- Restart the node with
--snapshot=true - The node will continue to sync and repair the corrupt data.
Changelog
BUGFIX
- #628 fix state inconsistent when doing diffsync

v1.1.5
v1.1.5 is a hard fork release.
v1.1.5 brings Bruno hard fork which introduces a real-time burning mechanism into the economic model of BSC. Please refer to BEP95 for more details. The Bruno hard fork is expected to happen at block height 13082000. The current block generation speed forecasts this to occur around November 30th at 08:00 AM (UTC). All clients are recommended to upgrade by November 30th.
We improved the diffsync protocol in this release and rolled it out as a stable feature. Diff sync improves the syncing speed by 60%～70% approximately according to the test. All full nodes are suggested to enable it by adding --diffsync in the starting command. Refer to BEP93 for more details.
Changelog
BUGFIX
- #509 fix graceful shutdown bug
IMPROVEMENT
- #536 get diff accounts by replaying block when diff layer not found
- #527 improve diffsync protocol in many aspects
- #493 implement fast getDiffAccountsWithScope API

v1.1.1
This release is a bug fix release.
All clients are recommended to upgrade.
CHANGELOG
IMPROVEMENT
- #355 miner should propose block on a proper fork
BUGFIX
- #350 flag: fix TriesInmemory specified but not work
- #358 miner: fix null pending block
- #360 pruner: fix state bloom sync permission in Windows
- #366 fix double close channel of subfetcher
Reducing Storage Occupation
If the storage occupation of the bsc client increasing dramatically, you may consider increasing the TrieTimeout setting in config.toml.
What does TrieTimeout means?
The bsc client will keep MPT(Merkle Patricia Tree) in memory. Once the block processing time exceeds the TrieTimeout, the client will persis MPT into disk. If the client crash, it can recover from recent persisted MPT. Increasing the TrieTimeout setting will reduce storage occupation, in exchange, it will need more time to recover from a crash.
The default setting before release v1.1.1 is 100000000000, it will persist MPT about every 35 minutes.
We change the default setting to 2000000000000 in this release, it will persist MPT about every 12 hours.
