Desde el blog de desarrollo de WordPress, nos llega el aviso del lanzamiento de una nueva versión. Esta entrega del CMS (3.4.2) está catalogada como de mantenimiento / seguridad y viene a solventar 20 bugs, tal y como informan en el área de la administración una vez que se instala.
Debido al alcance de los problemas resueltos y las mejoras que aporta, es más que importante aplicar la actualización lo antes posible.
Lista de cambios:
- Fixes some issues in the admin area where some older browsers (IE7, in particular) may slow down, lag, or freeze.
- Fixes an issue where a theme may not preview correctly, or its screenshot may not be displayed.
- Fixes the use of multiple trackback URLs in a post.
- Prevents improperly sized images from being uploaded as headers from the customizer.
- Ensures proper error messages can be shown to PHP4 installs. (WordPress requires PHP 5.2.4 or later.)
- Fixes handling of oEmbed providers that only return XML responses.
- Addresses pagination problems with some category permalink structures.
- Adds more fields to be returned from the XML-RPC wp.getPost method.
- Avoids errors when updating automatically from very old versions of WordPress (pre-3.0).
- Fixes problems with the visual editor when working with captions.
Version 3.4.2 fixes a few security issues and contains some security hardening. These issues were discovered and addressed by the WordPress security team:
- Fix unfiltered HTML capabilities in multisite.
- Fix possible privilege escalation in the Atom Publishing Protocol endpoint.
- Allow operations on network plugins only through the network admin.
- Hardening: Simplify error messages when uploads fail.
- Hardening: Validate a parameter passed to wp_get_object_terms().
