Geth v1.9.9 is yet another hard fork release! Don't worry, it's not a hotfix for Istanbul. v1.9.9 ships and enables the next hard fork, Muir Glacier, scheduled for block #9200000, expected around the 6th of January, 2020 (and block #7117117 on Ropsten, expected more or less around the same time).

Apart from Muir Glacier, the release:

  • Simplifies and cleans up the internals of the miner package (#20335, #19396).
  • Fixes a regression in restoring a deleted chain from the freezer (#20403).
  • Fixes a data race in the new iterator based discovery code (#20421).
  • Fixes a pointer reference issue in ABI big.Int decoding (#20412).
  • Fixes the help message of certain geth subcommands (#20203).

For a full rundown of the changes please consult the Geth 1.9.9 release milestone.
