v0.3.3

Changes

Fix: DNS resolver fallback for Android/Termux (#168)

• New kestrel-core/src/dns.rs — custom DnsResolver implementing reqwest::dns::Resolve
• Tries system config first (/etc/resolv.conf), falls back to Google DNS (8.8.8.8, 8.8.4.4)
• Injected into all reqwest client builders: providers, Telegram, Discord
• Fixes provider (ZAI/bigmodel) direct HTTPS connections on Android Termux

Fix: TLS certificate bundle (#167)

• Switched from rustls-tls-native-roots → rustls-tls-webpki-roots
• Mozilla CA bundle embedded in binary, no system certificate path dependency

Complete Android Termux fix chain

v0.3.2

Changes

Fix: Android/Termux TLS compatibility (#167)

• Switched from rustls-tls-native-roots → rustls-tls-webpki-roots
• Mozilla CA certificate bundle now embedded in binary
• Fixes all HTTPS requests failing on Android Termux (no system cert paths)

v0.3.1

What's Changed

🐛 Bug Fix

• Fix DNS resolution on Android Termux (#163, #164, #166): Added hickory-dns feature to reqwest to use pure Rust DNS resolver instead of system getaddrinfo, which fails on musl static binaries due to missing /etc/resolv.conf on Android.

🔧 Internal

• Bumped workspace version to 0.3.1
• Updated Cargo.lock with hickory-proto/resolver packages
