Version 9.0 contains a new version (V2) of the protocol environment, which is the set of functions that protocols can call. This new version is used by Florence, which is the current protocol on Mainnet. The release also contains Florence itself as well as its daemons (baker, endorser and accuser).
This release also contains the necessary configuration to join the
Florencenet test network, which runs Florence. To join Florencenet,
simply configure your node with
tezos-node config init --network
Version 9.1 fixes a performance and memory usage regression issue
Version 9.2 adds Granada, a protocol proposal for Mainnet featuring, among others, the Emmy* consensus algorithm, Liquidity Baking, and reduced gas consumption. Version 9.2 also improves how the mempool chooses which operations to keep. This should result in fewer endorsements being missed.
Version 9.3 fixes some cases where
MDB_MAP_FULL errors could occur
and reintroduces more
/normalized RPCs which were still missing
from version 9.1.
Version 9.4 fixes an issue in the mempool that caused too many operations referring to unknown blocks to be kept, resulting in the node running out of memory.
Version 9.5 fixes a bug that could result in a corrupted storage and in assert failure errors.
Version 9.6 increases the delay after which the endorser gives up on endorsing to 1200 seconds (previously 110 seconds), to prevent an issue where blocks that arrived too late were not endorsed at all, causing the next block to also be produced late.
Version 9.7 improves how the node handles pending consensus operations to remove costly computations in cases where they are not needed.
