Tmux: unknown option: c0-change-interval

Question

I have compiled tmux 1.9a and added the following to my tmux.conf file:

setw -g c0-change-interval 50                                                      
setw -g c0-change-trigger 75                                                       

However, this doesn't seem to work (I get some messages at startup that say they're unknown options). When I type setw -g c0-change-trigger 75 into tmux directly, I get:

unknown option: c0-change-interval

when I run tmux -V I get tmux 1.9a. My thinking is that the alias for the tmux PATH is set after I load tmux, and I'm actually running tmux 1.6, but I'm not aware of any way of checking what version of tmux is actually running.

When I run ps -u under COMMAND it just says tmux -2 new. Here is the relevant contents of my .bashrc file:

# this is where the compiled version of tmux 1.9a is:
export PATH="/home/quant/bin:$PATH"

# tmux                                                                          
# If not running interactively, do not do anything
[[ $- != *i* ]] && return
[[ -z "$TMUX" ]] && exec tmux

What is going on? As far as I know the c0-change-interval command is supported by tmux 1.9a, and this is what I seem to be running.

This isn't the original poster's problem but if anyone is coming up on this now the problem is actually that c0-change-interval and c0-change-trigger have been removed completely.

From: https://raw.githubusercontent.com/tmux/tmux/master/CHANGES

"The c0-* options for rate-limiting have been removed. Instead, a backoff approach is used."

So you should remove them from your configuration.
