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.
Its is time for some of the original Semiologic Pro plugins to be retired. They have served us well these many years. Some plugins are part of the WordPress core product (admin menus and favicons in WP 4.3), some have low usage or need (Feed Widgets), or technology has changed (RSS feeds vs. FB and Twitter feeds).
The following plugins are no longer going to be worked on nor maintained:
- Admin Menu (Free plugin)
- Article Uploader (Premium plugin)
- Fancy Excerpt (Free plugin)
- Favicon Head (forked version)
- Feed Widgets (Premium plugin)
- Frame Buster (Free plugin)
- Mediacaster (Premium plugin)
- Newsletter Manager (Premium plugin)
- Opt-in Front Page (Free plugin)
- PC Robots.txt (forked version)
- Search Reloaded (Premium plugin)
- Semiologic Affiliate (Premium plugin)
- Semiologic Cloner (Premium plugin)
- Subscribe Me (Free plugin)
- Subscribe to Comments Reloaded (forked version)
- WP DB Backup (forked version)
These join the prior plugins that were retired last few years:
- Autolink URI (Free plugin rolled into External Links plugin)
- Autotag (Premium plugin)
- Core Control Reloaded (forked version)
- Countdown Events Widget Reloaded (forked version)
- Custom Query String Reloaded (forked version)
- Deal.com Widgets (Free plugin)
- Democracy Poll Widget Reloaded (forked version)
- Do Follow (Free plugin)
- Feedburner Reloaded (forked version)
- Hitslink (Free plugin)
- Star Rating Reloaded (forked version)
- Unfancy Quote (Free plugin)
- Uploads Folder (forked version)
This means Semiologic and developments efforts will be more streamlined and focused. The Pinnacle theme continues to evolve with new functionality. You’ll also be seeing a change around how Semiologic Pro is packaged and released that will allow for frequent updates. For those that have current, valid subscriptions you’ll be grandfathered into the system. More details to follow in the next few months.
