In the blog post, Lefebvre said he believes most people are happy with the decision to drop 32-bit versions and that it makes sense in 2020. Computers with a 64-bit processor have been on the market since 2003, and most of the computers that have shipped in this decade are 64-bit ready (except several infernal netbooks).Users still running Mint on 32-bit hardware can use Linux Mint 19, 19.1, 19.2, or 19.3 until their end-of-life date in 2023.
