Key features include a new VmInitScript model, database migration for vm_init_script, and inclusion of vm_init_script in Vm#params_json. Added SYNC=1 to unbuffer stdout/stderr for clearer CLI output. Implemented performance improvements to reduce N+1 queries via eager loading and association-level changes, and upgraded core dependencies to stable releases. Strengthened security with a Rack CVE patch and a Ruby 3.4.7 runtime upgrade. Expanded Kubernetes/networking capabilities and firewall management, including private-subnet cross-project VM access, and comprehensive firewall rule support across API/SDK/CLI/Web UI.

Jan 1, 2025January 2025 — ubicloud/ubicloud: Delivered a focused set of UI polish, reliability, and data-model improvements that drive product clarity, security, and scalability. Key UI/UX work includes breadcrumbs on the Create Project page and broader UI/component coverage. Security and auth reliability were hardened through improvements to tag/access control flows, flash message handling, and error paths; upgraded core dependencies (Sequel 5.88.0, Tilt/Roda/RodAuth), and introduced robust per-project data scoping. Performance gains were achieved by fixing N+1 queries on VM show pages, improving DNS delete behavior, and tightening internal request handling. Infrastructure and tooling were modernized with CLI foundations, improved screenshot tooling, and infra cleanup (AlmaLinux 8 removal) to reduce operational debt. This combination reduces risk while enabling scalable multi-tenant usage and faster iteration.

Dec 1, 2024December 2024 highlights for ubicloud/ubicloud: delivered substantial UX, reliability, and security enhancements that improve business value and system stability. Implemented actionable error guidance for dependency load failures and invalid project names, modularized the user page (split into user, token, and policy editor) with 204 responses for deletes and clear feedback on token actions, and completed extensive cleanup to remove deprecated authorization resources. Advanced performance, caching, and data integrity through plugin-based improvements (NAME_MAP, static_cache), API request path optimizations, transactional token deletions, and a Sequel 5.87 upgrade. Strengthened access control and tagging with a new Authorization system using AccessControlEntry and Subject/Action/Object tags, including migrations and route-level permissions hardening. Expanded UBID and tagging capabilities (nested tag inclusion, resolve_map, vanity UBIDs) and pushed toward full test coverage with targeted specs, debug utilities, and development workflow improvements.
