Release Notes

First stable release on the 4.x line.

Highlights

• Stylesheet bug fix. The Gutenberg block no longer auto-loads form-theme.css regardless of settings. The block now respects the global "Default form theme" toggle and the per-form override, matching the shortcode behavior. (Cause: style field in block.json was force-enqueueing the theme stylesheet on any page that used the block.)
• Block inspector overhaul. New panels in the block sidebar:
• Form — pick a form, jump to its admin editor.
• Header — toggle to show the form title as a heading, choose H1–H6.
• Layout — alignment toolbar (left/center/right), max-width (px/em/rem/%/ch), HTML anchor id, custom CSS class.
• Stylesheets — per-block overrides ("use form/global setting", "force load", "force disable") for both form-theme.css and forms.css.
• Stable version. Bumped from 4.0.0-b9 → 4.0.0 across the plugin header, block.json, package.json, and readme.txt.

Upgrade notes

• No schema or data migrations.
• If you previously relied on the block always loading form-theme.css, make sure your global "Default form theme" setting is enabled, or use the new per-block "Force load" override.
• The max-width block attribute is validated against a strict CSS-length regex (px, em, rem, %, ch, vw, vh); other values are ignored.
