Mar 1, 2026March 2026 monthly summary for sapcc/helm-charts focused on reliability, security, and observability improvements driven by credential handling and alerting enhancements. Key fixes include securing NSXT password handling by escaping properly and splitting secrets for the NSXT agent and exporter to align with Vault rotation and INI escaping requirements, preventing agent crashes. Additionally, Slack alert routing for Neutron has been added via Kubernetes pod labels to improve monitoring and incident response.

Jun 1, 2025June 2025 focused on Neutron Helm chart improvements to support Caracal release, stability enhancements for migration policies and testing, and expanded tag policy capabilities. Key outcomes include placement service integration, backward-compatible policy behavior during migration, exemption of Tempest tests from rate limiting to stabilize tests, and addition of tag update/delete/get permissions across ports, subnets, and networks. The work positions the sapcc/helm-charts for Caracal readiness with version 0.2.7 and application version 'caracal', while delivering measurable business value through reduced risk during migrations, increased test reliability, and richer resource tagging capabilities.
