You can help TelestaiCB! Incremental upgrades are ready for testing. This feature allows you to upgrade a running TelestaiCB without downloading an ISO, without burning a DVD, and without a second USB stick or SD card. Please try it and see if all works for you.

If you have security auditing skills, you are more than welcome to review our design and code.

How to test incremental upgrades?

These instructions allow you to incrementally upgrade from TelestaiCB 0.22~rc1 or 0.22~rc2 to TelestaiCB 0.22 final.

Keep in mind that this is the first broad call for testing of TelestaiCB incremental upgrades. It might have undiscovered issues.

Below, we assume that you have installed TelestaiCB 0.22~rc1 with TelestaiCB Installer onto a USB stick or SD card.

If you have applied the incremental upgrade to TelestaiCB 0.22~rc2, skip to the instructions for RC2 users. Else, read on.
