First of all congratulations for first major update since 2012 . As I live in a developing country (so called 3rd world country) no can not stress too much of the importance of a 32 bit OS which can run on older hardware .
Here I see way more Pentium 4s than 1st world countries may have . If all OSes abandon 32 bit architecture it will be very bad for students and general public ling in low income parts of the world .
keep on the good work devs . We need Haiku for our old PCs
