• Fixed a bug of NonblockRenderer<T> and NonblockActionRenderer<T> where they had thrown ThreadStateException when any render events occured after disposed. [#1682]
• Log output compacted by removing duplicate exception messages. [#1632, #1677]

Libplanet 0.23.4

Released on December 24, 2021.

• Fixed a bug of NonblockRenderer<T> and NonblockActionRenderer<T> where they had thrown ThreadStateException when any render events occured after disposed. [#1682]

Libplanet 0.24.1

Released on December 16, 2021.

• Fixed a bug where Transaction<T>s were unstaged when they were not supposed to. [#1672]

Libplanet 0.24.0

Released on December 16, 2021.

Backward-incompatible API changes

• IStagePolicy<T>'s interface methods updated. Notably, all IStagePolicy<T> now accept BlockChain<T> as its parameter. [#1648]

• Fixed a bug where TxCompletion had broadcasted invalid transactions. [#1661]

Libplanet 0.23.3
