Ubuntu contributor Bryan Quigley is considering a proposal to make Ubuntu 16.04 LTS the last release of Ubuntu with 32-bit installation images.

Come April 2016, Intel 32-bit users might be on their last, overdue leg for upgrading their distribution. Quigley is considering a proposal to kill off the 32-bit install (ISO) images after that point while support for 32-bit applications on 64-bit Ubuntu would still be supported. The proposal would only involve Intel/AMD x86 with 32-bit ARM being unaffected given that 32-bit ARM is still very common to devices.
