One day later: a new version 
from http://bani.anime.net/etpro/ :
Changes from 2.0.0:
change: syringe uses “etmain” corpse hitbox, while everything else uses “rtcw” corpse hitbox
bugfix: constructibles didn’t work after a server pause
bugfix: constructibles timed out during server pauses (etmain stock bug)
bugfix: server crash on twl/twl-sw/cal when server started with sv_maxclients < 20 (etmain stock bug)
bugfix: pause/timeout announcements didnt broadcast (etmain stock bug)
If you have already installed 2.0.0, you can install 2.0.1 over it without problems.
The client pk3 has not changed in 2.0.1 so clients do not need to download anything new.
Good work to solve these bugs so fast, but I hope we can hang on to this version for a while :drink:
