Upgrades within the same major version number (for example from 7.0 to 
7.0.5 or 7.1) can usually be done with ``Check for Updates`` in Wing's
``Help`` menu.  Once you have upgraded, your previous preferences and
settings should remain in place.  After restarting Wing, you should 
immediately be able to start using the new version.  

The current version number can be found in Wing's `About box 
<script:about-application>`__.  A list of retained updates is also available
here, allowing reverting back to a recent versions.

If you are upgrading across major releases (for example from 6.x to 7.x), 
and in cases where the upgrade manager itself has changed, then 
you will need to download and install Wing as described in `Installing
<ref:install/installing>`__.  This will install the new version 
along side your older version of Wing.

New major releases of Wing will read and convert any existing Wing preferences,
settings, and projects.  Projects should be saved to a new name for use with
the new major release since they cannot be read by earlier versions.
