 WTForms Changelog
+Version 1.0.1
+Released February 29, 2012
-Version 0.6.4dev
-Not yet released
+- Fixed issues related to building for python 3 and python pre-releases.
+- Add object_data to fields to get at the originally passed data.
+Version 1.0
+Released February 28, 2012
 - Output HTML5 compact syntax by default.
 - Add localization support for WTForms built-in messages
+- Python 3 support (via 2to3)
 - Minor changes/fixes:
   * An empty label string can be specified on fields if desired
   * Option widget can now take kwargs customization
 # All configuration values have a default value; values that are commented out
 # serve to show the default value.

 # There are two options for replacing |today|: either, you set today to some
 for your file input, even if the form is prefixed.
+Why does blank input not go back to the default value?
+A key design decision of WTForms was that form data -always- takes precedence
+when there's a form submission. That is, if a field exists on a form, and a
+form was posted, but that field's value was missing, it will not revert to a
+default, but instead store an empty value (and in some cases cause a validation
+This is for a number of reasons:
+1. Security. If a form reverted to defaults on missing data, then an evil user
+   could potentially cause problems by submitting a hand-coded form with key
+   missing fields.
+2. Bug-finding. If you omitted a field in your template, it might fall through
+   to the default and you'd possibly miss it.
+3. Consistency.
+See the following mailing list posts for more discussion on the topic:

 How do I... [convoluted combination of libraries]
         If form data is processed, is the valuelist given from the formdata
         wrapper. Otherwise, `raw_data` will be `None`.
+    .. attribute:: object_data
+        This is the data passed from an object or from kwargs to the field,
+        stored unmodified. This can be used by templates, widgets, validators
+        as needed (for comparison, for example)
     To render a field, simply call it, providing any values the widget expects


 Built-in validators
+.. autoclass:: wtforms.validators.DataRequired
+   This also sets the ``required`` :attr:`flag <wtforms.fields.Field.flags>` on
+   fields it is used on.
 .. autoclass:: wtforms.validators.Email
 .. autoclass:: wtforms.validators.EqualTo
     passwords specified at all. Because Required stops the validation chain,
     EqualTo is not run in the case the password field is left empty.

+   fields it is used on.
