MetaInfo

Mandatory Update Required: Yes
Target Audience: all BSC Testnet users
Procedure: before upgrading, review the deprecated flags and config fields listed above and confirm their removal has no impact on your node; once confirmed, binary replacement is sufficient:

  • --journalfile: no longer has any effect, safe to remove
  • --miner.txgaslimit: per-transaction gas limit is now enforced by EIP-7825; confirm EIP-7825 behaviour meets your requirements before removing
  • --enablebal: no longer has any effect, safe to remove
  • --multidatabase: single-database mode is now the only option; confirm your data directory is compatible
  • --txpool.overflowpoolslots: overflow pool is removed; review your txpool capacity settings if you relied on it
  • [Eth] EnableBAL in config.toml: must be removed before upgrading — will cause a startup error if left in
  • [TxPool] OverflowPoolSlots in config.toml: silently ignored, but recommend removing to keep config clean
    Schedule(Timeline): TBD
