new version of hivedrop / alt-p2p (OSS) released today

alt-p2p allows P2P (peer-to-peer) data transfers between 2 computers on the Internet . Fast UDP-based packet transfer, works across common routers/switches/firewalls, performs NAT traversal without port forwarding, UPNP, etc.

alt-p2p-ui is the Desktop GUI for alt-p2p (Mac, Windows)

What's new in v0.3.0:
* NEW - New Settings tab for advanced users (set timeouts, intervals, retries)
* NEW - Ability to enable fallback to TCP or UDP relay (via coordination server). Useful when UDP hole punching fails.
* Improved - Bump alt-p2p dependency to v0.3.0 (for TCP & UDP relay support)

Key Features of alt-p2p:
- Transfer data directly between 2 computers (Win or Mac, Linux soon)
- No third party clouds. No file / file size limits.
- Faster transfers (2-4X faster than cloud-based solutions)
- Secure, private transfers using E2EE (end-to-end encryption)
- Open source for maximum transparency , security, and audits

alt-p2p OSS repo is now available on github!

alt-p2p enables encrypted peer-to-peer file transfer over UDP with NAT traversal. Built for alt-core, a decentralized virtual filesystem.

Peers connect through a lightweight coordination server, punch through NATs, establish a DTLS-encrypted channel, and transfer files with reliable delivery, congestion control, and integrity verification.

Features
- NAT traversal - UDP hole punching with symmetric NAT support
- End-to-end encryption - DTLS 1.2 with pre-shared key authentication
- Reliable delivery - SACK-based selective acknowledgment with retransmission
- Congestion control - AIMD with slow start, fast retransmit, and adaptive receiver window
- Integrity verification - SHA-256 hash checked by receiver after transfer
- Resume support - Interrupted transfers resume from last checkpoint via .p2p-partial sidecar files
- Progress display - Real-time progress bar with speed and ETA
