I'm keen to instal this newest release from elementary OS. Unfortunately, I don't get an option to choose between 32 or 64 bit upon download. Does this mean that 32-bit support is dropped altogether? I cannot find the answer on the official pages from elementary.
No, there is no 32-bit iso. Only 64bit.
There is no official 32 bit elementary ISO but you can get quite close to the official experience by doing the following:
Install Ubuntu 16.04.
Add the elementary PPAs:
sudo add-apt-repository ppa:elementary-os/stable sudo add-apt-repository ppa:elementary-os/os-patches sudo apt-get update
Install the elementary desktop:
sudo apt-get upgrade sudo apt-get install elementary-desktop
Reboot and select the
Pantheon session at the login screen.
I found an older 32 bit version @ http://linux.softpedia.com/get/System/Operating-Systems/Linux-Distributions/Elementary-OS-67717.shtml
