 ### Notes on Updates
 
-#### Location of tmp / data dir
-From version 0.70 on the tmp dir is renamed to 'data-bot-bash' to reflect the fact that not only temporary files are stored. an existing 'tmp-bot-bash' will be automatically renamed after update.
+#### removal of TMUX
+From version 0.80 on TMUX is no longer needed and the bachsbot command 'attach' is deleted. Old function 'inproc'
+is replaced by 'send_interactive'. send_interactive does checks if an interactive job is running internaly.
+Pls check if you make use of inproc and remove it including the old checks, e.g.
+```bash
+if tmux ls | grep -v send | grep -q "$copname"; then inproc; fi
+# or
+[ checkprog ] && inproc
+```
+must be replaced by ```send_interactive "${CHATD[ID]}" "${MESSAGE}"```
 
+### Do not edit commands.sh
 From version 0.60 on your commands must be placed in 'mycommands.sh'. If you update from a version with your commands
 in 'commands.sh' move all your commands and functions to 'mycommands.sh'.
 
+#### Location of var / tmp / data dirs
+From version 0.70 on the tmp dir is renamed to 'data-bot-bash' to reflect the fact that not only temporary files are stored. an existing 'tmp-bot-bash' will be automatically renamed after update.
+
 From version 0.50 on the temporary files are no more placed in '/tmp'. instead a dedicated tmp dir is used.
