v1.3.0 — UI Overhaul, Bug Fixes & Accessibility

What's New in v1.3.0

Bug Fixes

Backend

• IP reassignment on subnet creation was broken for root-level subnets — the old code only walked the parent chain. Rewritten to use ipaddress.subnet_of() across all existing subnets, so IPs are correctly migrated regardless of nesting depth.
• N+1 query patterns eliminated in get_ips, import_ips, and export_ips by loading subnet data once and building a lookup dict.
• Numeric IP sort — IPs are now sorted by their integer value in get_ips and export_ips, not lexicographically.
• CIDR normalization — host bits are silently normalised on subnet creation (strict=False).
• Hardcoded debug=True removed; debug mode now reads the FLASK_DEBUG environment variable.
• Security: removed print() statements that leaked password hashes to stdout on login.
• API error messages translated from German to English.

Frontend

• Subnet tree was limited to 2 levels deep. Replaced with a recursive buildTree(parentId) — unlimited nesting depth now works correctly.
• Stale closure in context menu useEffect caused the event listener to re-register on every open/close. Fixed with functional setState and empty [] dependency array.

New Features

• Toast notification system — all alert() calls replaced with a professional bottom-right toast (auto-dismiss after 4 s, success/error/info variants with icons, aria-live for screen readers).
• Accessibility — aria-label added to every icon-only button (theme toggle, logout, settings, import/export, edit/add/delete in subnet tree).
• Form loading states — subnet and IP modal submit buttons are disabled and show a spinner during API calls.
• Escape key closes all modals (subnet, IP, delete confirmation, settings).

UI Redesign

• Dashboard: dark sidebar (slate-900, always), resizable pane, breadcrumb navigation, compact IP table with semantic colour-coded architecture badges (VM, Kubernetes, Firewall, IoT Device, etc.), sticky table header, professional modals with rounded-xl shadow-2xl.
• Login page: split layout (dark branding panel + form), password show/hide toggle, loading state on submit, styled error message.
• SettingsModal: section headers, scrollable content, coloured feedback messages.

Performance

• subnetById Map (useMemo) replaces Array.find() for O(1) subnet lookups.
• filteredIps and subnetPath wrapped in useMemo.
• Lazy state initialisation in ThemeContext and SettingsModal.

Docs & Tooling

• Added CLAUDE.md for AI coding assistant context.
• Rewrote README.md, DEVELOPMENT.md, CICD.md, k8s/README.md, frontend/README.md — all now in English, updated for v1.3.0.
• Full CHANGELOG.md added.
• UI/UX design skills added at .agents/skills/.
