Darkkle v2.3.0

Darkkle 2.3.0

Darkkle 2.3.0 establishes the new Darkkle identity and converts the project into a community-oriented open-source repository.

Highlights

• The extension name shown by the browser is now simply Darkkle.
• Row and column header labels receive improved protection from being obscured by highlight redraws.
• Scrolling and multi-cell selections receive more robust retained-canvas cleanup.
• Existing settings backups from prior builds remain importable.
• The repository now includes issue forms, feature wish-list channels, Discussions templates, contribution rules, governance, security guidance, automated validation, and release tooling.

Install

Download Darkkle-v2.3.0.zip, extract it, enable Developer mode in the browser's extension-management page, and choose Load unpacked on the extracted folder.

Reload the extension and refresh existing spreadsheet tabs when upgrading an unpacked installation.

Important limitation

The spreadsheet grid uses private canvas behaviour that can change without notice. This release significantly improves header-highlight handling, but future interface changes may require additional community fixes.

Community status

Darkkle is maintained by volunteers. The repository owner may not respond or publish releases regularly. Users and developers are invited to reproduce bugs, test proposed changes, improve documentation, and become trusted triagers or maintainers.

Testing status

The browser test checklist in TEST_CHECKLIST.md has not been completed and recorded for this release. This release is published as a pre-release for that reason.

Completed: repository validation (npm run check), covering Manifest V3 structure, referenced files, JavaScript syntax, secret scanning, permission and host scope, visible branding, and release-package contents. The published archive was independently downloaded and verified against its SHA-256 checksum, with manifest.json confirmed at the archive root.

Not completed: the browser checklist, including the header-highlight regression scenarios, frozen panes, hidden rows and columns, zoom levels, multi-range selection, keyboard-shortcut behaviour, theme controls, and per-spreadsheet profile and backup persistence. No browser or operating-system versions have been recorded.

Treat this build as untested in a live spreadsheet. Community testing results are welcome in the release-testing issue. Please state the browser version, the operating system, and exactly which scenarios were and were not covered. Partial, honest results are useful.
