Unreleased

Russian UI translation. On first launch the application asks which language to use (1) English, 2) Русский) and writes the answer to a fresh config.ini next to dhcpsrv.exe. To change the language later, edit language = en / language = ru in that file — the comment at the top of the file explains how, in both languages.
config.ini becomes the future home for other settable defaults (pool, lease, server IP) — currently only [General] language is consumed.
Bilingual README.ru.md linked from the main README.md.

Update check no longer interrupts startup with an interactive prompt. If a newer release is available, the header line now shows a quiet update available (vX.Y.Z) hint right-aligned in dim grey — no key press required.

Bumped __version__ from 1.1.1 to 1.1.3 after the v1.1.2 release packaged a binary that still self-reported as v1.1.1 (the source constant was not bumped before tagging). The source is now once again the single source of truth.

Dropped the made by engelgardt line from the startup banner too — author credit lives in the README only.

Embedded application icon in the exe (via PyInstaller --icon assets/icon.ico).

The persistent header panel no longer prints the made by engelgardt line. Author credit moves to the one-off startup banner and the README only — the always-on UI stays tighter.

Auto-update check on startup. Polls GitHub /releases/latest with a 3-second timeout. If a newer version is available, prints a yellow notice and offers to open the download page in your browser. Silent on offline / API errors.

First public release on GitHub.
Single portable .exe (~12 MB) — no Python required on target machines.
Full-screen TUI built on rich: header with server config + live counters (Leases / Pkts / DISCOVER / REQUEST / RELEASE), clients table (#, IP, Hostname, MAC, Last seen, Ping), scrolling events panel.
Hardcoded sensible defaults: server 10.10.10.1/24, pool 10.10.10.2..10.10.10.51 (50 addresses), lease 7200 s, TFTP option (66/150) = server IP.
Only one prompt at startup: NIC selection.
Adapter filter — only physical wired NICs appear in the picker (no Wi-Fi, VPN, virtual, Hyper-V, VMware, VirtualBox, TAP/TUN, WireGuard, OpenVPN, Tailscale, ZeroTier, Bluetooth, Loopback, WAN Miniport).
Reliable ping check via the TTL= substring in ping output — a real BMC reboot is reflected as red --.
Pure event-driven UI refresh — no flicker on resize or while idle.
Auto-fit clients table to terminal height ((+N more — enlarge the window) marker on overflow).
Scrollback cleared on startup so mouse-wheel doesn't expose pre-launch text.
