====
- Added entity-prefix attribute to the include directive.

0.17.0
======
- Added include function. Includes can be used to include the content of a
  another configuration file in a form configuration.
- Added inheritance function. Inhertance can be used to inherit from a base
  form and onyl modify small parts of the form.

0.16.1
======
Bugfixrelease

- Fixed broken JS code to enable and disable fields because of conditionals.
  This also fixed broken saving of checkboxes.

0.16.0
======
- New option "reset-value" for conditionals.
- Improved conditionals. For conditionals with "reset-value" attribute set to
  "true" the following bahaviour has been improved:
  If the conditional becomes False and fields within the conditionalcondit
  become readonly or invisible, the value of all fields will be deleted to an
  empyt value. If the conditional becomes True again before the form has been
  submitted the initial values of the fields within the forms will be
  restored.
- Make readonly checkboxes and radio buttons not clickable.

0.15.2
======
Bugfix release:

- Fix handling of empty string values and make them unicode too.
- In case of InfoRender try to get the value from the item even if the entity
  is not included in the form. This is needed to be able to work with the
  value attribute.
- Set datatype attribute of hidden fields to fix data conversion on client
  side.

0.15.1
======
Bugfix release:

- Improved rule evaluation. Only try to get values for rules evaluation if the
  field is in the form. Reduces number of warnings in logfile.
- Fixed rendering of Radiofields. Removed support for fields which can have
  mulitple values as a Radiofield can only handle one value.
- Fixed client side data conversion of date fields for rule evaluation.


0.15.0
======
- Added new renderer "Textoption". A textoption field is basically a selection
  field which can be used to set multible values. In a textoption field the
  values can be entered in a textfield. The textfield has support for
  autocompletion which offers the available options.
- Added support for form wide errors and warnings using external validators.
  Form wide errors and warnings are shown at the top of every page of the
  form.

0.14.1
======

  styling of the field element(s).
- Added configuration attribute to the label to configure the position of the
  numbering in the label.
- Added configuration attribute to set a background for the label.
- Changed margins and font sizes of headings in the form to make the form more
  compact and improve the visual difference of the headings. Margins are
  reduced and differences between headings are larger now.

0.13
====
- Added attribute to configure how to display the help on the field. Show help
  on fields as tooltip per default. On behaviour can be reestablished by
  setting the display attribute of the help to "text".
- Remove default "Reset" form button. Asking people using forms shows
  that almost nobody is using a reset button in the forms. If you want
  to have a reset button than you need to define a custom button bar now
  in the form.
- Hide submit buttons on pages of forms with no input elements.

0.12
====
- Extract text form button for internationalisation.
- Fixed affix of outline sidebar on forms.
- Implement remove_filtered for dropdown elements too.

0.11
====

  is used together with the entity, and layout sections to generate a
  specification of the forms.
- Added formspec.py command to generate the speficication. 

0.10
====
- Modified "onchange" event for textfield. Detect if user stopped typing in
  a textfield and trigger evaluation of rules after 750ms automatically.


0.9.13
======
- Fixed type detection for VARCHAR fields.

0.9.12
======
- Raise deserialisation error when time format ist wrong.

0.9.11
======
- Performance Improvement: Do not evaluate all conditionals when a values
  changes in the form. Only evalute the conditionals which are affacted by the
  change.

0.9.10
======
- Enabled translation of the error messages while type conversion to python.
- Limit integer data type to 4byte (which is the value for integer datatype in
  a postgres database.)

  the current date.)
- Moved converters for serialisation and deserialisation into its own module
  (converters.py)
- Started to improve client side rule evaluation. In case the input element
  has the data type attribute set then try to convert the value of the field
  into the right representation for rule evaluation.
- Started to improve performance on form initialisation. First store the
  fields in a dictionary per page to make the access to fields on a specific
  page faster.

  form configuration. E.g generate the SQLAlchemy model.
- Added optional request param for form initialisation. The current request
  from a wenframeform can no be provided to the form. This might be usefull
  while rendering with external renderers.

0.4.0

  the next form rendering.

Form-Rendering:
- Splitted up rendering of forms. The Fieldrenderer now renders label, field,
  help and errors seperately for each field.
