I merged into Neubot code for MacOSX that allows to automatically download updates from the development channel instead of from the stable channel. Basically, following this development channel you will be able to run release candidate versions and you will help me to test the code before the release.

This code will be released with 0.4.8 and this feature will be, of course, disabled by default. To enable it, you need to create the configuration file /etc/neubot/updater:

sudo install -d /etc/neubot
sudo install -m644 /dev/null /etc/neubot/updater

Inside this file write the following text:

channel testing

Then stop and restart Neubot:

sudo launchctl stop org.neubot
sudo launchctl start org.neubot

Many thanks to Alessio Palmero Aprosio and Francesco Corazza, who helped me to test this new feature!
