WordPress 3.4.2: Maintenance & Security

WordPress 3.4.2 has just been released and is now available for download. This update is a maintenance and security release for all previous versions.

After nearly 15 million downloads since 3.4 was released not three months ago, we’ve identified and fixed a number of nagging bugs, including:

â– Fix some issues with older browsers in the administration area.
â– Fix an issue where a theme may not preview correctly, or its screenshot may not be displayed.
â– Address pagination problems with some category permalink structures.
â– Improve plugin compatibility with the visual editor.
â– Prevent improperly sized header images from being uploaded.
â– Avoid errors with both oEmbed providers and trackbacks.

This version also fixes a few security issues and contains some security hardening. The vulnerabilities included potential privilege escalation and a bug that affects multisite installs with untrusted users. These issues were discovered and fixed by the WordPress security team.
