## Change logs
* v0.1.11 - Support 16 bits per pixel
* v0.1.10 - Allow to sync clipboard between local and remote machine, CTRL+SHIF+V to paste text from local to remote machine
* v0.1.9 - improve stability
* v0.1.7-8 - remove package dependencies, use web assembly for jpeg decoding, improve rendering performance and connection stability
