v3.0rc1

• New: Use CSS grids for better layouts. If you would like your column layouts to show in Internet Explorer, you'll need to turn on the old styling in the Formidable -> Global settings. The grids use a 12-column layout with classes that range from frm1 (1 column of 12) to frm12 (span all 12 columns).
• Enhancement: Run install on an API route instead of the admin ajax route and make sure there won't be multiple instances of the install running at once.
• Enhancement: Add frm_rtl class to forms with styles set to RTL for easier styling.
• Enhancement: Use the options instead of transients for checking for updates. Some types of caching store transients indefinitely.
• New: Add frm_before_get_form hook
• Tweak: Remove the placeholder fallback javascript for old versions of IE. No need to give everyone extra scripts to load.
• Tweak: Only show the user login for a user id field when the display name is empty. Don't show it as a fallback for other user values.
• 3.0 Fix: Correctly add classes to the admin body and prevent other plugins from overriding it for the new styling
