Dec 1, 2025

December 2025 monthly summary for basecamp/fizzy: Delivered a focused set of business-value features, reliability improvements, and observability enhancements across Fizzy SaaS and the core app. Key outcomes include improved email governance and user experience (expiration notes on emails/magic links, dashboard visibility for signups), backend reliability (mailer retry logic, identity validation, and verified_at-based spam controls with a backfill), and stronger observability and testing infrastructure (GC tuning, console auditing, dev seeds). Stability fixes address critical regressions (Action Cable disconnect on deactivation, ill-formed remote images) while providing testing groundwork (staff seeds) and a revert of a restricted-column-change change for safer operations. These efforts reduce failed communications, improve compliance with anti-spam controls, and accelerate troubleshooting and onboarding.

2025-09 Monthly Summary for basecamp/activerecord-tenanted focused on stability, security, and scalability enhancements. This sprint delivered major dependency updates and semantic versioning, improving security posture and compatibility: v0.2.0, v0.3.0, v0.4.0, and v0.4.1. Architectural/config improvements were introduced, including renaming DatabaseConfigurations::RootConfig to BaseConfig, Railtie-driven config handler registration, a new LRU queue utility, support for max_connection_pools, adoption of cattr_accessors, and proactive connection pool reaping at max size. Documentation work began on the Guide with initial improvements. Key bug fixes improved user experience and reliability: consistent #inspect tenant formatting and TenantSelector middleware no longer renders a 404. Security and automation gains were achieved via CI hardening (read-only), pinned action versions, RuboCop security cops, and Dependabot scheduling.
