Version 12.0~rc2

Version 12.0 contains a new version (V4) of the protocol environment, which is the set of functions that protocols can call. This new version is used by protocol Ithaca, which is a proposal for the successor of Hangzhou. This release candidate also contains Ithaca itself as well as its daemons (baker and accuser — there is no endorser for Ithaca) and the ithacanet built-in network alias for the Ithacanet test network.

The second release candidate (12.0~rc2) replaces protocol Ithaca (PsiThaCa) with Ithaca2 (Psithaca2) and updates the ithacanet built-in network alias to the new version of Ithacanet, which uses protocol Ithaca2 instead of Ithaca. This second release candidate also includes a number of bug fixes and improvements related to Ithaca and to the storage backend.
