Changelog

0.14.2

---

Released 2017-01-10

• Fix bug where FlaskForm assumed meta argument was not None if it
  was passed. (278_)

.. _278: pallets-eco/flask-wtf#278

0.14.1

---

Released 2017-01-10

• Fix bug where the file validators would incorrectly identify an empty file as
  valid data. (276, 277)

• FileField is no longer deprecated. The data is checked during
  processing and only set if it's a valid file.
• has_file is deprecated; it's now equivalent to bool(field.data).
• FileRequired and FileAllowed work with both the Flask-WTF and
  WTForms FileField classes.
• The Optional validator now works with FileField.

Released 2017-01-06

• Use itsdangerous to sign CSRF tokens and check expiration instead of doing it
  ourselves. (264_)

• All tokens are URL safe, removing the url_safe parameter from
  generate_csrf. (206_)
• All tokens store a timestamp, which is checked in validate_csrf. The
  time_limit parameter of generate_csrf is removed.

• Remove the app attribute from CsrfProtect, use current_app.
  (264_)
• CsrfProtect protects the DELETE method by default. (264_)
• The same CSRF token is generated for the lifetime of a request. It is exposed
  as request.csrf_token for use during testing. (227, 264)
• CsrfProtect.error_handler is deprecated. (264_)

• Handlers that return a response work in addition to those that raise an
  error. The behavior was not clear in previous docs.
• (200, 209, 243, 252)

• Use Form.Meta instead of deprecated SecureForm for CSRF (and
  everything else). (216, 271)

• csrf_enabled parameter is still recognized but deprecated. All other
  attributes and methods from SecureForm are removed. (271_)

• Provide WTF_CSRF_FIELD_NAME to configure the name of the CSRF token.
  (271_)
• validate_csrf raises wtforms.ValidationError with specific messages
  instead of returning True or False. This breaks anything that was
  calling the method directly. (239, 271)

• CSRF errors are logged as well as raised. (239_)

• CsrfProtect is renamed to CSRFProtect. A deprecation warning is issued
  when using the old name. CsrfError is renamed to CSRFError without
  deprecation. (271_)
• FileField is deprecated because it no longer provides functionality over
  the provided validators. Use wtforms.FileField directly. (272_)

0.13.1

Released 2016/10/6

• Deprecation warning for Form is shown during __init__ instead of immediately when subclassing. (262_)
• Don't use pkg_resources to get version, for compatibility with GAE. (261_)

.. _261: pallets-eco/flask-wtf#261

Released 2016/09/29

• Form is renamed to FlaskForm in order to avoid name collision with WTForms's base class. Using Form will show a deprecation warning. (250_)
• hidden_tag no longer wraps the hidden inputs in a hidden div. This is valid HTML5 and any modern HTML parser will behave correctly. (217, 193)
• flask_wtf.html5 is deprecated. Import directly from wtforms.fields.html5. (251_)
• is_submitted is true for PATCH and DELETE in addition to POST and PUT. (187_)
• generate_csrf takes a token_key parameter to specify the key stored in the session. (206_)
• generate_csrf takes a url_safe parameter to allow the token to be used in URLs. (206_)
• form.data can be accessed multiple times without raising an exception. (248_)
• File extension with multiple parts (.tar.gz) can be used in the FileAllowed validator. (201_)
