WP BrowserUpdate v6.0.1

This patch release corrects the plugin's original source strings to en-US so WordPress.org translations can provide locale-specific variants such as en-GB. It does not change settings, browser detection, frontend behavior, or bundled runtime behavior.

WP BrowserUpdate v6.0.0

This is a major release focused on stronger compatibility, clearer configuration, and a more self-contained browser-update.org integration.

Breaking changes

• Requires WordPress 6.0 or newer.
• Replaces the legacy settings storage with a structured settings model.
• Removes developer callback settings from the admin UI and saved settings model.
• Existing WP BrowserUpdate 5.x settings are migrated automatically.

What changed

• Ships the browser-update.org runtime with the plugin, so visitor-facing notifications no longer need to load scripts, styles, or default notification links from browser-update.org.
• Improves compatibility with strict Content Security Policies and tracker blockers by loading same-origin plugin assets.
• Adds broader admin coverage for the browser-update.org customisation options used by WP BrowserUpdate.
• Adds separate thresholds for Microsoft Edge and Internet Explorer.
• Preserves exact dotted browser versions such as 137.0.3912.63 instead of reducing them to major versions.
• Keeps browser-version checks on the WordPress admin side using the WordPress HTTP API and a host allowlist.
• Hardens settings validation, custom CSS handling, frontend script loading, and external admin links.

WP BrowserUpdate v5.1.1

Current stable release focused on security hardening, cleaner admin UX, and better browser-version handling.

Highlights

• Added free-text browser version input (replacing dropdown selection).
• Added browser version checks with caching.
• Added wpbu_browser_version_cache_hours filter (default: 6 hours).
• Updated admin settings structure to better match WordPress admin standards.
• Improved sanitisation and nonce handling across settings fields.
• Reduced unnecessary remote lookups on the settings page.
• Fixed frontend uncaught error for invalid/unexpected browser version strings.

Compatibility

Requires PHP 7.4 or newer.

WP BrowserUpdate v4.8.1

Legacy maintenance release for sites that still need the 4.x line.

Highlights

• Optimised code.
• Bug fix.
• Updated outdated browser versions.

Compatibility note

This is the final 4.x release.
If your environment cannot move to PHP 7.4+, this is the recommended legacy branch from the project history.
We recommend updating to the current release line as soon as your environment supports it.
