Sep 1, 2025September 2025 monthly performance summary for aiida-core: delivered stability improvements, startup performance enhancements, and developer-experience improvements. Key outcomes include fixing a PostgreSQL OperationalError during bulk insert with a regression test, refactoring SqliteZipBackend initialization to pre-check migration necessity and centralize version validation for faster startup, and introducing a .git-blame-ignore-revs file to reduce noise in git blame. These changes reduce runtime errors in bulk operations, shorten startup times, and improve history clarity for maintainers and users, delivering clear business value via more reliable operations and faster deployment readiness.

Jan 1, 2025January 2025 (aiida-core, aiidateam/aiida-core) focused on stabilizing storage accounting for RemoteData by correcting disk-size reporting across du variants. Implemented a robust disk size calculation by switching from du -s --bytes to du -s --block-size=1 and disabling apparent-size usage, with corresponding test updates. This reduces cross-OS discrepancies (notably across Ubuntu variants) and improves reliability of storage metrics used in workflows and quotas. No new user-facing features; primary value is correctness, maintainability, and cross-environment consistency.
