• #2571: Request the approval for database migrations (@yangby-cryptape)

• #2604: Allow miner http basic authorization (@driftluo)

• #2569: Add rpc generate_block_with_template to IntegrationTest rpc module (@quake)

  This PR adds generate_block_with_template rpc, so that dApps can get block template from get_block_template rpc, and then add or remove tx / proposal / uncle data in block template, and finally submit it via this rpc to control the newly generated block data.

Bug Fixes

• #2556: Resolve peer store dump issue (@quake)

Improvements

• #2525: Manually trigger compaction after freeze (@zhangsoledad)

  • Drawbacks: Even we use DeleteRange apply to delete the range of keys, seems Rocksdb still hasn't implemented the feature of using seek() to skip until the end of range delete end yet.
    Rocksdb iter seek slows down dramatically when there are many deletes.
  • Workaround: Manually call CompactRange() for the range to delete, this approach can solve the problem.

• #2595: Set prepare_for_bulk_load option for migration (@zhangsoledad)

• #2611: Smaller block status map during IBD (@yangby-cryptape)
