We’ve just installed Jetpack on blogs.middlebury.edu. This plugin replaces the WordPress.com stats plugin that many use to keep track of how many people are viewing their sites.
If you own or are an administrator on a site that used the WordPress.com stats plugin, we encourage you to update to JetPack. For more information, see:
Plugins > Jetpack
Update: We have had reports that updating from WordPress.com Stats plugin to Jetpack may prevent access to historical site statistics. If such statistics are important to you, we recommend not updating to Jetpack until these issues are resolved.
JetPack also has a number of other features including a Twitter widget, support for LaTex markup and a spelling, grammar and style checker. For more information, see:
