That's exactly what it fixes. I've had no issues on my server for the last few weeks, players are happy that all new grenades are now available to auto-buy, in addition to all of the previous fixes.
For future updates Richard can incorporate them into the code-base, you can recompile yourself using the provided source-files, or when I update it myself I'll update this thread.
Edit: Updated the first zip file, I accidentally re-added the old translation file when I fixed the weapons.txt. If you've already added it to your server, reupload weapons.txt and the zombiereloaded.phrases.txt for the v2 zip and all will be good again
