Compatibility: declared Tested up to: 7.0 (the current WordPress release). 1.0.9 shipped with 6.8, which Plugin Check flagged as outdated (6.8 < 7.0).
Readme: shortened the 1.0.9 upgrade notice to stay under the 300-character Plugin Check limit. No behavioural code changes since 1.0.9.
1.0.9
GDPR (critical): decoupled email_hash() from wp_salt(). The previous implementation used wp_salt() as the hashing factor, so any admin running wp config shuffle-salts (a routine WordPress security hygiene step) would have silently invalidated every email hash already stored in wp_owfo_submissions — every subsequent DSAR erasure request would then have failed to match the historical rows, leaving PII the visitor explicitly asked to delete sitting in the database with no error trail. The plugin now uses a dedicated, plugin-owned salt persisted in the owfo_dsar_salt option (generated once at activation, never regenerated, autoload OFF). Existing installs receive the salt on first call via lazy bootstrap, but no existing hash needs to be re-computed — only newly-written submissions use the new salt, and DSAR matching keeps working on rows written under either salt provided neither is rotated. Recommended for ALL sites.
Fixed: Tested up to corrected to 6.8 (was incorrectly set to 7.0, a WordPress version that does not exist yet — would have been flagged by Plugin Check as an invalid version reference).
Fixed: admin settings save now routes from_email and default_recipient_email through sanitize_email() instead of the generic sanitize_text_field(), catching malformed inputs at save time instead of silently storing strings that wp_mail() would later reject.
Fixed: route_handle_submission REST endpoint now returns a 404 when called against a submission id that does not exist, instead of silently returning {ok: true} after a no-op wpdb->update.
Fixed: anti-spam link-density scan now also detects bare www.example.com URLs (no protocol prefix), which spambots commonly use to slip past the previous https?:// regex.
Compliance: shipped the non-minified friendly-challenge-0.9.18.module.js next to the existing .min.js, per WP.org Plugin Check requirements (vendored minified JS must ship with the human-readable source alongside).
Compliance: added .distignore at the plugin root so the WP.org SVN-deploy pipeline excludes dev-only files (node_modules, tests, build configs) from the published ZIP.
Compliance: created the empty languages/ directory at the plugin root so the make pot build step has a known output location and translators can drop their .po files in a predictable place.
1.0.8
Compliance: bumped Tested up to from 6.9 to 7.0 to satisfy the Plugin Check outdated_tested_upto_header rule (the header must point to the current WordPress release for the plugin to surface in directory searches). [Note: 7.0 is not a valid WordPress version — corrected to 6.8 in 1.0.9.]
1.0.7
Fixed (regression): the legacy [owf_form] shortcode rewrite in post content now actually runs on sites that transited through 1.0.5. The 1.0.6 release introduced the SQL REPLACE but gated it behind the existing owfo_migrated_owf_prefix flag — which any 1.0.5 install already had set to ‘1’, so the rewrite was skipped on the largest existing fleet. The step is now gated by its own independent flag owfo_migrated_shortcode_content so it runs exactly once per install regardless of the version transit path.
Fixed: the shortcode-content REPLACE now excludes post_type IN (‘revision’, ‘auto-draft’) and post_status IN (‘inherit’, ‘auto-draft’). Rewriting historical revisions would have silently re-authored users’ version history.
Fixed: hCaptcha invisible-flow second-submit deadlock. The callback registered on hcaptcha.render() only captures the FIRST submit’s resolve — every subsequent submit hung forever (button locked, spinner stuck). The render callback now dispatches through holder._owfoHcaptchaResolve, which is updated on every submit before execute() is called.
Bumped Requires at least from 6.0 to 6.3 to match the apiVersion: 3 declared in blocks/form/block.json (block.json apiVersion 3 was introduced in WP 6.3).
1.0.6
Fixed (intent, but see 1.0.7 for the actually-working version): wired the in-place migration of legacy [owf_form id=”…”] shortcodes in post content. The migration was correctly added to migrate_from_owf_prefix() but shared the owfo_migrated_owf_prefix idempotency flag with the four pre-existing migration steps, which meant sites that had already run 1.0.5 skipped the new step entirely. Fix landed in 1.0.7.
Compliance: renamed the four captcha script handles from owf-captcha-* (3-char prefix) to owfo-captcha-* (4-char prefix). Aligns with the WordPress.org plugin guideline that the prefix rule covers script/style handles, not only PHP identifiers.
Compliance: the Gutenberg block now ships a real block.json manifest under blocks/form/ (api-version 3) so Plugin Check stops emitting block_no_block_json and the block is discoverable by the editor inserter metadata API.
Fixed (partial — see 1.0.7 for the hCaptcha second-submit fix): front-end captcha token retrieval now actually supports hCaptcha (invisible flow with render + execute) and Friendly Captcha (proof-of-work widget with doneCallback polling). Previous versions silently shipped empty tokens for both providers, which the server rejected with score +100 — all hCaptcha / Friendly Captcha submissions were therefore dropped client-side without any error message.
Removed: signature is no longer listed as a supported field type. It was advertised in 1.0.x but render_field() and sanitize_value() only ever fell back to <input type=”text”>. The field count in the description is now 16 (was 17). A real canvas-based signature widget will land in a future release.
1.0.5
Addressed the second-round feedback from the WordPress.org plugin review team.
Removed the legacy [owf_form] back-compat shortcode — the < 4-character prefix didn’t meet the WordPress.org plugin guidelines. Existing posts had already been migrated in place to [owfo_form] by the 1.0.3 upgrade routine, so the removal only affects content that was never opened for editing after that upgrade.
Fixed a broken Terms of Use URL pointing to Friendly Captcha in the External Services section (/legal/terms-of-service/ → /legal/terms/).
1.0.4
Added an uninstall.php handler so all plugin data (custom tables, options, form posts) is cleaned up on plugin deletion.
Added a LICENSE.txt file at the plugin root pointing to the GNU GPL v2 text.
Hardened the anti-spam time-trap with a server-anchored HMAC. The previous design’s client-set timestamp was trivially forgeable; the new check binds the gate to a signed render timestamp.
Captcha vendor scripts (Turnstile / reCAPTCHA / hCaptcha / Friendly Captcha) now load only on pages that actually render a form, instead of every page of the site once a provider is configured.
Added a composite index (form_id, status, id) on the submissions table — eliminates filesort on the admin list filter under high row counts. Existing installs pick the index up automatically on upgrade.
Settings option is now autoloaded, replacing the per-request SELECT it triggered on cache-cold pages.
Shared budget between the retention purge and the orphan-files sweep so a single cron tick never exceeds a known total of disk + DB ops. Filterable via owfo_purge_budget_per_tick.
Internal: spam reject threshold is now a named constant (OWFO_Spam::REJECT_THRESHOLD) filterable via owfo_spam_reject_threshold; routing parameters are stripped from the REST submit payload before validation; baseline check on the uploads directory is memoised per request; OW Shield IP-reputation integration explicitly documented in the external-services section.
1.0.3
Addressed feedback from the WordPress.org plugin review team.
Renamed internal prefix from owf_ to owfo_ to satisfy the 4+ character minimum required by WordPress.org. Existing installations migrate automatically on activation; the legacy [owf_form] shortcode continues to work for backward compatibility.
CSS and JavaScript are now loaded via wp_enqueue_style() / wp_enqueue_script() instead of inline <style> / <script> blocks. Assets only load on pages that actually render a form.
File uploads now use the WordPress core wp_handle_upload() API instead of move_uploaded_file().
Form schemas saved through the admin UI are recursively sanitized (every string leaf passes through sanitize_text_field()).
Documented every third-party CAPTCHA provider (Turnstile, reCAPTCHA, hCaptcha, Friendly Captcha) in the new == External services == section with what data is sent, when, and links to each vendor’s terms and privacy policy.
i18n source language switched to English; French shipped as a translation file under languages/ow-forms-fr_FR.po. languages/ow-forms.pot template included for community translators.
Conversion tracking is now opt-in (default OFF) — gtag events fire only after explicit admin opt-in.
Friendly Captcha widget is now self-hosted under assets/js/vendor/ instead of loaded from an external CDN.
Removed plugin “Powered by” link from the admin header.
Hardened SQL preparation, input sanitization, output escaping, and nonce verification across all admin and REST surfaces.
