There was a problem hiding this comment.
After the new version of tendermint is released, replace the branch by version.

This change mainly fixes the memory leakage issue if c_level_db is enabled. For go_level_db, it doesn't have this issue. |
There is an issue for using rocksdb in tendermint. tendermint/tendermint#3736 |

nodes from cache on deletion * small changes in teh mutable tree * correct storage version key * auto set fast version in SaveVersion * avoid exporting new methods of the immutable tree * go fmt * Fix
