Adobe has announced the end of support for Adobe Acrobat and Reader 2015.
On April 7, 2020, support will finish for these versions of the PDF reader and creation software, keeping in line with the tech giant’s position to withdraw support after a maximum of five years of general availability.
Once April passes, Adobe will “no longer provides technical support, including product and/or security updates, for all derivatives of a product or product version (e.g., localized versions, minor upgrades, operating systems, dot and double-dot releases, and connector products),” the company says.
