Client Release: 0.7.20 "An Explosive Resurrection"

[Nka19]

Some things that don't seem to have been mentioned:

To toggle barricade health, press the "i" key.
There is now a "Replace Items" button that can be accessed by pressing "Esc" and clicking on "Character Screen." This button is useable during the prep time following a respawn wave, and it makes it so that you no longer need to enter spectator and rejoin the team if you want to bring in more items.

You should mention that they shouldn't go spec in preperation time at all, or else they wont spawn. When all bots are killed preperation time starts and everyone who are dead respawns, and those who wants to replace items that waren't dead yet, can do so using the Replace Items button, all who goes spec in that time wont respawn. That's something many got confused about.

Edit: also about character screen, there's even a shorter button "C" .
