The new Windows Phone Dev Center is giving Microsoft some problems. After several apps have been reported to not install on older phones a bug in the Dev Center was discovered. This bug has been messing with the digital signatures on newly published apps, and making them incompatible with older versions of WP.
Microsoft already has a fix in the works, but in the meantime they are playing it safe and halting all app publishing. Until the fix is in place developers will have to patiently wait for their app to be published, including our very own WinSource app.
