1.0.0

Added before the first release:

🚀 DNS servers can now be a hostname or URL No longer limited to IP addresses (1.1.1.1) — you can enter a domain name or URL such as dns.adguard-dns.com. The address is automatically resolved to an IP before the VPN is enabled.

🛡 AdGuard preset One-tap button with dns.adguard-dns.com — blocks ads and trackers in two taps. Presets are now arranged in a neat 2×2 grid: Google DNS, Cloudflare, OpenDNS, AdGuard.

⚙️ Secondary DNS field is now optional You can use just a single DNS server. The field label now reads "Secondary DNS (optional)".

✨ Empty fields with hints On a fresh install the DNS fields are empty — only hints are shown (1.1.1.1 or dns.example.com). If you leave a field empty, it falls back to 1.1.1.1 automatically.

📱 Widget shows the DNS actually in use The widget now displays the real address being used (instead of an empty value) when DNS is ON.

🏷 Renamed The app is now called DNS Changer Widget.

🔐 Signed release APK The release build is signed with a persistent keystore via GitHub Secrets (KEYSTORE_BASE64 / KEYSTORE_PASSWORD) — a stable key, not a new one on every build.

Instead of making several separate releases for each feature, I decided to finish these changes before the first release and include everything at once.
