Version 2.2a is almost fully compatible with version 2.1. Below follows a list of
differences. 

LIBRARY APPLICATIONS
====================

- Freezing of forms and objects has changed. Unfreezing a form now only
  redraws the objects that where changed while the form was frozen. This
  is normally what you want and is a lot faster. If the application
  though assumes the entire form is redrawn, put a call to
  fl_redraw_form() just before unfreezing it. This new behaviour of
  freezing and unfreezing forms makes the freezing and unfreezingf of
  individual objects or groups obsolete. So don't use the calls
  fl_freeze_object() and fl_unfreeze_object() anymore. You will get a
  warning when you do. In the next release the routines will be removed.

- Buttons now behave slightly different. If you move the mouse out of
  them before releasing it, the buttons won't be fired. (This is more
  compatible with most other user interfaces.)

FORM DESIGNER

- No changes.

INTERNALS
