  • Currently testing and merging the last PR likely to be included in mainnet release https://github.com/rchain/rchain/pull/2875 https://rchain.atlassian.net/browse/RCHAIN-3989 Modify RevVault to use TreeHashMap instead of a synchronous map.

  • Merged - Deposit Slashed Funds into coop wallet

  •  Hardening

    • Will be tackled in a future release - Replay errors - https://rchain.atlassian.net/browse/RCHAIN-3917  and https://rchain.atlassian.net/browse/RCHAIN-3943

    • Merged - Recently introduced CloseBlock System deploy seems to cause indeterminate errors

    • Merged - Slashing for invalid blocks sometimes causes issues. We are looking into the proper policy and code changes to resolve this.

  • Casper and block storage

    • Merged - https://github.com/rchain/rchain/pull/2854  Make Casper replay on top of least-effort block - Helps improve long proposal times

  • dApp developer tools and documentation. 

    • Merged - Exploratory Deployments feature  - Initial version completed, to allow developers to run deployments and rollback. Exploratory deploy allows clients to get data from the blockchain. Exploratory deploy is executed on top of the last finalized block. Future versions will support custom block hash and other nice features.Method can be executed only on read-only RNode.

    • This is API3 described in Obtaining Data  https://rchain.atlassian.net/browse/RCHAIN-3979 https://rchain.atlassian.net/browse/RCHAIN-3981  and among other things, allows to check for balance without paying REV  https://rchain.atlassian.net/browse/RCHAIN-4002
