v2.0.0-rc1

The rc1 release candidate for replicated security v2.0.0.

Date: June 1st, 2023

Unlike prior releases, the ICS v2.0.0 release will be based on the main branch. v2.0.0 will contain all the accumulated feat PRs from previous releases, along with other PRs that were merged to main, but not released to production. After v2.0.0, we plan to revamp release practices, and how we modularize the repo for consumer/provider.

Upgrading a provider from v1.1.0-multiden to v2.0.0 will require state migrations. See migration.go. See the provider module's ConsensusVersion in module

Upgrading a consumer from v1.2.0-multiden to v2.0.0 will NOT require state migrations. See the consumer module's ConsensusVersion in module
