Release notes

The feedback button now opens a single shared form on the tools index. You can pick the app from a dropdown, so all suggestions and bug reports arrive in one place.

The privacy tiers were clarified: green now explicitly covers tools that make stateless server calls (nothing is stored), and blue is reserved for tools that persistently store user data on the server - currently none do.

Unified the suite look: the app now shares the common design system with every other tool — the same colours, fonts and footer, plus a new top bar to switch between tools.

The footer now shows a privacy indicator for this tool: a green dot means it runs entirely in your browser, a yellow dot means it keeps data on your device, and a blue dot means it stores results on the server.

Version 1.0: all pages now have an up-to-date XML sitemap, so search engines can find everything. The previous release is now documented under its own version.

This release notes page now reads the current version and deployment time directly from the app, so the latest entry updates itself with every deployment.

The app is now available in five languages (English, German, French, Italian and Spanish) with a language selector. Added a page hit counter, a feedback form and a visit statistics page. All info pages are now multilingual.

Added this release notes page, a help page and a sitemap. All three pages are linked in the footer.

Added the subnet plan, which splits a network into smaller subnets and lists them with host range and broadcast address, plus the CIDR quick reference and a binary view for IPv4.

First release of SubnetCalc with IPv4 and IPv6 address calculation, prefix and subnet mask input, presets and the most important network key figures.
