Fix - Multisite network mode now performs periodic checks only on the main site and syncs shared network status metadata.
Fix - Entry/export column registration now uses canonical pb_ref_* keys only, preventing duplicate "Referral Tracker" columns after upgrading from legacy versions.
Fix - Added one-time export migration to convert saved legacy numeric entry-grid columns to canonical pb_ref_* keys and remove duplicates.
Fix - Added one-time historical backfill for wp_gf_entry_meta so missing/empty pb_ref_* rows are populated from legacy numeric tracking field values.

New - "Protect Scripts from Minification" option under Advanced settings adds data attributes to exclude tracking scripts from caching/optimization plugins (WP Rocket, LiteSpeed Cache, SG Optimizer, Autoptimize, Cloudflare Rocket Loader).
New - Admin UI now displays the tracking JS file paths so users can manually exclude them in caching plugins.
Enhancement - "Enable by Default" setting is now a checkbox with clearer guidance on all-forms behavior and per-form overrides.

New - "Remove Data on Uninstall" option under Data & Privacy settings. Unchecked by default — plugin data is preserved unless the user explicitly opts in before deleting.

Fix - One-time migration automatically removes any orphaned tracking fields that were accidentally saved into form metadata by earlier plugin versions.

Enhancement - Centralized built-in source lists into the Constants class, removing duplicate arrays across files.

Fix - Editing an entry in the admin no longer wipes tracking values or other form fields. Tracking fields are excluded from the entry edit screen so GF never overwrites real field values with empty POST data.
Fix - A gform_after_update_entry safety-net restores any tracking values that are still cleared during an entry edit.
Enhancement - Tracking fields now use GF_Field_Hidden instead of CSS-hidden text fields, reducing interference with third-party plugins.

Fix - Front-end field population restricted to plugin-owned inputs in the 218523x namespace to prevent values from being injected into unrelated fields.
Fix - Google Ads Tracker migration now suspends gform_form_post_get_meta so dynamically-injected fields are never saved into permanent form records.
Fix - Entry list tracking columns now reject IDs outside the plugin namespace, preventing tracking data from replacing real field values in the Entries table.

New - Click ID field and {pb_ref_clid} merge tag captures the first detected click ID (gclid, fbclid, msclkid, etc.) for direct CRM mapping.
Fix - Paid ad clicks now always force a full attribution update, even when a first-touch cookie already exists.
Fix - UTM fields not present in a new paid visit are now cleared so stale values from a previous session cannot bleed through.

New - Custom Sources with label, match field, match type, match value, and priority ordering.
New - Append Organic/Ads Labels setting for custom source labels.
New - Tracking fields can be added as selectable columns in the Gravity Forms entry list.
