This issue continues fixing problems introduced in the 3.4 version (after the security update). This version of course also includes the security update and all previous versions.
This version mostly corrects new functionality and restores some of the APIs that were changed in 3.4. This should provide better support for contrib modules that build on FileField. There are some minor CSS and markup changes in this release that may affect sites using the "Generic file" formatter. These changes allow for better display of file names and icons in views and layouts that float content.
