Mar 1, 2026March 2026 monthly summary for Panfactum/stack focused on enabling scalable, secure production infrastructure, stabilizing deployments, and improving developer productivity. Key outcomes include production-grade GitHub Actions runners with dynamic provisioning using kube-karpenter via the kube_gha Terragrunt module (production us-east-2) enabling automatic scaling and redundancy. Bitnami image and Helm chart transitions were completed by migrating remaining images to the bitnamilegacy registry and updating references (including kube_nats and kube_monitoring) and removing the node image cache to improve pull reliability and stability. Quota safeguards were implemented to avoid apply failures from over-quota requests, and deployments were restored by aligning VPC, OpenSearch, and NATS configurations. Cluster and tooling upgrades were executed to support newer features and security: EKS default version moved to 1.33, Terraform AWS provider upgraded (6.x), and OpenTofu updated to 1.9; associated provider pins and documentation were refreshed. Website apex-domain handling was fixed and Authentik Helm chart upgraded to 2024.10.5 to incorporate upstream fixes. Changelog tooling was modernized with a structured YAML schema, validation tooling, and release-script improvements, moving to directory-based entries for better traceability. Build tooling and developer experience were enhanced with BuildKit upgrade, non-CI devshell behavior fix, and batch-formatting hooks. Repository structure was refactored to hoist reference infrastructure to the repo root for clarity and deployment simplicity. Grist deployment to production was introduced but currently reports an errored status; configuration work is ongoing.

May 1, 2025Month: 2025-05 — Panfactum/stack delivered a concise set of features, stability fixes, and developer experience improvements that enhance security, performance, and operability for production deployments. Key features include Terragrunt hooks for standardized infrastructure orchestration, OpenSearch dashboards with remote storage integration (v3), and CLI enhancements (resumability for env add). Deployment workflows were accelerated by intelligently skipping unnecessary init steps, reducing toil and deployment times. Extensive bug fixes across CLI, AWS integrations, Direnv, and Kubernetes-related flows improved reliability and security (e.g., unloading credentials on devshell boot, DNSSEC KMS policy fix, and multiple nginx instances per host). Documentation and site architecture were modernized to boost developer onboarding and product clarity. Business value: faster, more predictable deployments; improved security posture; easier onboarding and maintenance; stronger observability and compliance with updated docs and guidelines.

Mar 1, 2025March 2025 — Panfactum/stack: Delivered a broad set of platform improvements across marketing, security, pricing, cloud, and deployment workflows, delivering measurable business value and stronger operational resilience. Highlights include GA-enabled Marketing Website Refresh, hardened email deliverability with DNS security (SPF/DKIM/DMARC) and domain redirects, a pricing and savings calculator overhaul with support for new tiers, and robust Kubernetes infra with on-demand clusters and reliability improvements. Deployment pipelines were accelerated via parallel builds, intelligent skip logic, and multi-arch Docker support, while cloud providers were kept up-to-date (AWS/Terraform) and data reliability improved through remote S3 restore for kube_pg_cluster and public S3 presigned URLs for service accounts. Minor documentation improvements completed to improve usability and changelog accuracy. A nix installer version parsing fix prevented false detections.
