v4.5.15.17 release

v4.5.15.17 had one bug fix.

Significant defect addressed

• Corrected an issue preventing images from exiting the draft state after uploading those images into a gallery enhancement in the rich-text editor and then publishing the parent asset. For example, an editor starts a new article and adds a gallery enhancement in the rich-text editor. The editor then bulk uploads images into the gallery and publishes the asset. The bulk-uploaded images never appeared as published.
