The Global Synchronizer software follows a release cadence that includes periodic patch releases addressing bug fixes, performance improvements, and security updates. These releases use semantic versioning within the current 0.5.x series.

​
Release process

Patch releases (e.g., 0.5.8 → 0.5.9) are published as needed when bug fixes or security improvements warrant an update. Each patch release includes:
  • A release bundle published to the Splice releases page on GitHub
  • Updated Docker images for all components (SV app, validator app, scan, wallet, sequencer, mediator, CometBFT)
  • Updated Helm charts for Kubernetes deployments
  • A corresponding Canton release (e.g., Canton 3.4.7 ships alongside Splice 0.5.9)

​
How to stay informed

Release notifications are communicated through:
  • The #validator-operations Slack channel for operational updates
  • The #validator-operations-onboarding Slack channel for new validators
  • Release notes published on the Splice documentation site

​
Applying patch releases

Patch releases within the same minor version (0.5.x) are designed to be applied without synchronizer migration. The general upgrade process:
  1. Review the release notes for any breaking changes or prerequisites.
  2. Update your Helm chart version or Docker image tags.
  3. Roll the deployment — components can typically be upgraded one at a time.
  4. Verify health through the node’s health endpoint and monitoring dashboards.
Some patch releases include important caveats. For example, 0.5.7 introduced a performance regression and should be skipped in favor of 0.5.8. Always read the release notes before upgrading.
For the full upgrade procedure, see Validator Upgrades or SV Upgrades.

​
Version skipping

You can skip intermediate patch versions when upgrading. For example, upgrading from 0.5.3 directly to 0.5.9 is supported. However, review the release notes for all intermediate versions to identify any required Daml package upgrades or configuration changes that may apply.

​
Relationship to Canton releases

Each Splice release is built against a specific Canton version. The Canton release notes document fixes and improvements at the protocol and infrastructure level, while Splice release notes cover application-level changes (Scan, Wallet, Validator, SV app, Daml packages).
