kaikozlov/localsend.koplugin v1.3.0 on GitHub

KOReader Plugin

Send files from your e-reader: New "Send file..." and "Send current book" options let you send files directly from KOReader to any LocalSend device on your network
Device discovery: Automatically scans for LocalSend devices on LAN and via WebRTC signaling
PIN prompt when sending: When sending to a PIN-protected device, you'll be prompted to enter the PIN instead of getting a generic error

"Scan again" option: If no devices are found, you can retry the scan without starting over
Better error messages: Send errors now show specific messages (device not running, connection refused, etc.)

Folder transfers stay together: When receiving folders with extension routing enabled, files now stay in their original folder structure instead of being scattered to different directories by type
Send file picker respects home folder lock: The file picker for sending now starts above the locked home folder, matching the behavior of the destination picker

Trusted devices (PAIR): Pair devices to skip PIN verification on future transfers. Use --config-dir to enable persistent device pairing
Custom STUN servers: Configure custom STUN servers for WebRTC with --stun-servers for corporate networks or privacy

Persistent rate limiting for WebRTC connections (survives reconnection attempts)
Enhanced path traversal protection
Constant-time PIN comparison to prevent timing attacks
