5 Commits • 1 Features
Feb 1, 2026February 2026 focus was on enhancing usage analytics, simplifying UI, and stabilizing deployment pipelines to deliver clear business insights and reliable release processes. Key enhancements to the Usage Dashboard introduced two new metrics (COUNT_CONTENT and COUNT_OF_CONTENT_TYPES) with minimal-profile testing, i18n support, and a straightforward SQL-backed metric type, improving accuracy and visibility for content administration. UX refinements removed the misleading refresh control, replaced the dynamic Last Updated timestamp with a static cache notice, and standardized terminology from "Languages" to "Locales" for consistency. In parallel, CI/CD reliability was boosted by upgrading the macOS runner to macos-latest in the Publish Starter workflow, reducing cancellation issues and improving reproducibility of builds. These efforts collectively increase data quality, user trust, and engineering velocity for faster business decisions and smoother deployments.

Nov 1, 2025November 2025: dotCMS/core focused on CI/CD infrastructure modernization to improve build compatibility and maintainability. Delivered a macOS runner migration to macos-15-intel, introduced flexible, variable-based runner version configuration, and added repository-level variables to control Intel and Silicon macOS runners. This aligns with GitHub recommendations, reduces build flakiness across Intel Macs, and simplifies future updates. The work is tracked under issue #33802 and PR #33804 with no new risks introduced to main pipelines.

Jun 1, 2025June 2025 monthly summary for dotCMS/core focused on stabilizing CI/CD workflow for manual publishing. Delivered a targeted fix to ensure repository checkout prior to downstream steps by introducing a conditional 'Checkout repository' step when the workflow is triggered with inputs ('empty' type) and dry-run is false. This change resolves a missing checkout in the manual publishing flow and prevents starter workflow execution failures, improving reliability of the publish process in the core repository.
