Sem-Cache already delivered great results in website performance when compared to WP Super Cache and W3 Total Cache. With version 2.11 of Sem-Cache, performance is improved and a few hidden bugs squashed. Simply upgrade the plugin. I would recommend turning caching off then back on to get the cached rebuilt immediately.
Version 2.5 of the Pinnacle theme has been released. The primary focus of this release is allowing for additional, and more complex, Header and Footer areas. Semiologic Reloaded introduced a Header and Footer Boxes Bar to which widgets can be added. This bar was then added into the Header/Footer. This provided for columnar type content in those areas. This functionality was kept in Pinnacle to allow for migration from Reloaded to Pinnacle.
When Semiologic and Semiologic Pro was first created by Denis, WordPress was still in its infancy. Now that it’s 2015, WordPress has greatly matured and Jetpack has brought wordpress.com functionality to those that self-host their blogs and websites. Some technology, like RSS, has been supplanted by Facebook and Twitter news feeds. Given all of this, some of the Semiologic plugins and third party plugin forks just aren’t practical to maintain. With Wordpress being released every 3-4 months, having to test and release plugins just to say they are version compatible, is simply just a pain.
Not sure why it took us so long but Semiologic now has a Github account. You can simply find it under Semiologic. I know, novel.
Currently some of the old, forked plugin that were part of the original Semiologic Pro are there. This account also serves as the home for the master Semiologic Pinnacle and Featured Child themes. These are now public for the world to see, fork and contribute.
