To give users time to prepare, Adobe has announced this week that when Lightroom 6 is released (no date yet), it will require Mac OS X 10.8 or above (Mountain Lion, Mavericks, Yosemite), or a 64 bit version of Windows 7, 8 or 8.1. According to Adobe, “Focusing our work on more modern operating systems and architectures allows us to spend more time adding functionality requested by users, including additional advanced imaging features and improving general application performance.”
