Mainnet September 2019#

This release contains the patch necessary to correctly activate protocol Babylon.

During the testing phase of protocol 005_PsBABY5H, a bug was identified (more details in the Bug affecting Bigmaps in 005_PsBABY5H). The tezos-node in this release contains a corrected version of Babylon, protocol 005_PsBabyM1, that will be activated in place of 005_PsBABY5H if the promotion vote is successful.

Any node running the May release, in case of a successful promotion vote, will activate protocol 005_PsBABY5H, which contains a bug affecting bigmaps in smart contracts.

We advise users to update to this release so that the corrected protocol 005_PsBabyM1 will be activated.

In case of a negative promotion vote, any release of the tezos-node will simply proceed to a new proposal phase.

Changes introduced by Babylon (including RPC calls) can be found in the protocol documentation.
