1.2.9

• Fix: resolve undeclared variable issue in fieldset conditions (change $fieldtype to $field_type).
• Fix: resolve issue with radio fields incorrectly being marked as required – each item in the radio field was being marked as required (using aria-required=true) when only the fieldset should have been. Reference: http://stackoverflow.com/questions/8509481/aria-required-in-a-radio-group= 1.2.8
• Fix: resolve issue with radio field ‘other’ option not including a label. Added screen-reader only labels for radio and input field assigned to ‘other’ option.

• Feature: add condition to exclude links with a class of ‘target-self’ from opening in a new window.

1.2.7

• Fix: fixed error in code for date field – resulting in on screen PHP error messages or the field not appearing.

1.2.6

• Feature: field description now included in a fields ‘aria-describedby’ attribute – giving screen reader users easy access to the fields description when jumping through fields and skipping page content.
• Feature: wrap single file upload field in a field set – providing screen reader users with the label of the upload field – instead of hearing ‘browse’ they will hear the title of the field followed by ‘file upload’
• Feature: add ‘accept’ attribute to single file upload field, providing screen reader users a list of accepted file types when they select the file upload fields
• Feature: add screen reader only text below single file upload fields, providing screen readers users a human understandable description of the file type and file size restrictions placed on the field (if specified for the field)
• Maintenance: removed HTML ‘required’ attribute that was being applied by plugin – this was causing issues. Will be restored once this has been resolved. aria-required still applied to required fields, which is widely supported by assistive technologies.

1.2.5

• ** REMOVED ** Feature: change ‘Save and continue’ link to a button. This provides better accessibility by providing ‘Save and continue’ as a form field – making it listed along side with the ‘Previous’, ‘Next’ and ‘Submit’ buttons when a screen reader user lists all form fields. e.g. JAWS + F5.

1.2.4

• Fix: required checkbox and radio fields missing ‘required’ asterisk since version 1.2.2.

1.2.3

• Feature: links in form body, such as field descriptions or HTML fields, will be made to open in a new window. A title is added or appended to any existing title for screen reader users which reads ‘this link will open in a new window’.

1.2.1

• Fix: changed validation alert so that HTML ‘new line’
  is replaced with JavaScript ‘new line’ /n
• Fix: added condition to column and field changing functions so that they only function on the front end – not in the Gravity Forms forms builder
• Maintenance: improved how date format instructions are built.
• Feature: ‘list’ field image buttons (add new row, delete row) are not keyboard accessible. Added to to replace with actual buttons they are keyboard accessible.
• Feature: add aria-describedby for website field – ‘enter a valid website URL for example http://www.google.com’
• Fix: un-did ‘required’ attribute for checkbox field – it unduly made ALL checkboxes required, rather than just one.
• Maintenance: moved CSS to its own file.

1.1.0

• Feature: added aria-describedby for date fields – providing screen reader users with the instructions on how to type into the field, for example ‘must be dd/mm/yyyy format’
• Feature: added screen reader only words for required fields – providing screen reader users with the word ‘required’ in addition to the default star
• Feature: added aria-describedby for fields that have failed validation – making it easier for screen reader users to determine why a field has failed validation
• Feature: improved validation message. Message now reads ‘There were 2 errors found in the information you submitted.’ and is followed by a list of each field that did not pass validation. Each item in the list is a clickable link, taking the user directly to the field.
• Feature: added browser alert if form did not pass validation. If the form did not pass validation, the first thing the user should see or hear is ”There were 2 errors found in the information you submitted.’ followed by the list of errors. When the user clicks past the alert the browsers focus is taken to the on screen validation message and links to errors.
