WordPress 2.6 SVN has a new feature called Speed Up! It will use Google Gears to to locally cache images, scripts and stylesheets to speed up load times. I hope by final it will support using the admin fully offline since using a plugin just to cache some images and scripts doesn’t really seem worth it.
Microsoft, Google, Verisign and IBM have joined OpenID. I think this will finally make OpenID a reality. All the site I run support OpenID through plugins and I think you will soon see CMS’s supporting OpenID natively.
