eBook Platform Transition from Adobe to Harman
Starting July 2025, Harman will manage Adobe eBook components, updates, and support.
A Ongoing platform support and feature development for Adobe eBook Platform Components (Adobe Content Server, Reader Mobile SDK, and Adobe Digital Editions) is now being handled by Harman Connected Services, Inc., a wholly‑owned subsidiary of Samsung Electronics Co., Ltd. As of July 2025, Adobe transitioned these responsibilities to Harman, including future releases and technical maintenance. Harman now manages and distributes any new updates, enhancements, bug fixes, and support requests directly.
To access the latest versions of Adobe eBook Platform Components (Adobe Content Server, Reader Mobile SDK, and Adobe Digital Editions), report issues, request new features, or receive technical assistance, visit Harman's Digital Editions support channels.
