# ezQuake Manual: Upgrading to new version

This page will tell you how to comfortably upgrade from older to new versions of ezQuake. To know how to upgrade from FuhQuake, visit the Installation manual page.

## Upgrading from 1517 and older to 1727 and 1732

- Independent physics feature is now enabled by default. Follow the link for more info. If you want to disable them, use this command-line option when running ezQuake:
  `-noindphys`
- Head Up Display defaults has been changes. If you notice different frags and teamfrags placement, try this:
  `frags extra_spec_info 0
  teamfrags extra_spec_info 0`
  To make sure your HUD configuration is exactly the same as in previous version of ezQuake, use the Keeping exact old settings guide from below.
- For MultiView Demos (MVD) we do automatically load custom Head Up Display (HUD) configuration from now on. To disable this behavior, use:
  `mvd_autohud 0`
- Behavior of mp3_volume has been changed. If you had custom scripts for increasing and decreasing your media player volume, those won't work anymore. To increase or decrease your media player volume from within the client, use following commands:
  `mp3_volume +0.1
  mp3_volume -0.1`
  This has been changed to avoid media player volume problems when loading your config.
- You can make your commandline more friendly by changing following option:
  `+set vid_displayfrequency X` into `-freq X`
  Also you can throw away "+set cl_independentphysics 1" because it's on by default now.
- cl_nolerp default value has been changed to 0

For full description of what has been changed see the changelog

## Upgrading to 1517

- You might get fullbright textures on walls in this build. That's because we have fixed r_fullbright behavior and you have set variable to 1 in belief it has something to do with fullbright skins. To get rid of this behavior, just use:
  `r_fullbright 0`

## Keeping exact old settings

You are expected to install (or extract) the client package as if it was your first ezQuake installation. But note that as we are modernizing default settings to meet current gaming standards, these changes might appear in your new ezQuake version and might disturb users who like to have everything pixel perfect as in their previous version.
To make sure nothing is changed since your previous installation of ezQuake, save your full config also with default values. To do this, before you use the cfg_save command, type this into the console:
`cfg_save_unchanged 1`
After this just save your config with
`cfg_save yourname`

Now you can install new version of ezQuake and load your full config in it using the `cfg_load yourname` command.
