Release 2430 distribution

[jpraynaud]

Why

In order to deploy new features, improvements and bug fixes, we need to release a new distribution.

What

Create and release a new distribution 2430

Important

• Activate Cardano transactions certification in release-preprod and pre-release-preview
• Upgrade to Cardano node 9.1
• Upgrade release-mainnet disk

How

Phase 1: Prepare distribution

• Upgrade repository dependencies
• Check that all minor versions of all crates have been bumped for breaking change (if needed)
• Check if versions of repository linked crates are correct for publication to crates.io(mithril-common, mithril-client)
• Check if Cardano minimum supported versions in networks.json must be updated following the runbook
• Merge a PR for rotating the CHANGELOG.md (set the distribution version)
• Create a draft PR for rotating the documentation
• Merge a PR that upgrades release-mainnet VM data disk to pd-balanced

Phase 2: Rollout pre-release distribution

• Activate the certification of Cardano transaction in pre-release-preview
• Tag and deploy a 2430.0-pre pre-release distribution on the pre-release-preview network
• Fill 'Highlights' and release notes section in the pre-release page on GitHub
• Make sure pre-release-preview is working as expected
• Make sure libraries version next have been published on npm registry
• Run an all green client multi-platform test in the CI
• Run an all green aggregator stress test in the CI
• Run a Cardano transaction prover benchmark:
  • Store results in the issue
  • Make sure that there is no performance drop since last release
• Announce the pre-release on discord channel
• Announce any breaking change in #cardano-scaling slack channel for pre-release
• Announce any breaking change in #mithril-lace slack channel for pre-release
• Wait for at least 3 signers running the new version (could be more if era change is tested) over at least 2 epochs

Phase 3: Rollout release distribution

• Announce upcoming downtime of 30 minutes on the release-mainnet aggregator for maintenance in discord channel
• Tag and deploy a 2430.0 release distribution on the pre-release-preview network

• Make sure pre-release-preview is working as expected
• Update networks compatibility table in release notes
• Activate the certification of Cardano transaction in release-preprod

• Make sure release-mainnet is working as expected
• Make sure release-preprod is working as expected
