• Enhanced invitation capabilities, allowing more users to be invited directly from the invitations pane.

• Improved post-submission redirects to optionally pass submitted data as URL query parameters.

🧹 Code Cleanup & Maintenance

• Removed unused and legacy code to reduce technical debt and improve maintainability.

🐛 Bug Fixes

• Fixed issue where embedded forms wouldn’t open the first time in the preview shown during configuration.

• Resolved issues related to filtering submissions based on custom date field responses.

• Addressed issues with bulk deletion of submissions that occasionally caused timeout errors.
