The developers of the Palemoon browser plan to increase the CPU requirements in ready-made builds. The reason given is the desire to use AVX processor instructions to significantly speed up the browser. The change is planned for summer 2024.
To use the new builds, you will need a processor that supports the second version of the x86-64 microarchitecture (x86_64-v2), which has been used by processors since approximately 2009, starting with AMD FX and the first generation Intel Core i7 (Nehalem). The x86_64-v2 microarchitecture is distinguished by the presence of extensions such as SSE3, SSE4_2, SSSE3, POPCNT, LAHF-SAHF and CMPXCHG16B. For owners of older processors, it is proposed to use a 32-bit assembly for Windows, use packages from the Linux distribution, or build it yourself.
It is also worth noting that over the past week, users of the Palemoon browser have been experiencing failures when passing Cloudflare's DDoS attack protection. At some point the problem was resolved, but at the end of the week it reappeared.
