What's Changed

• Proof-of-Space performance improvements - backports the bucketed-array PoS table construction from Abundance (replacing sorted Vecs with fixed-size bucketed arrays) for better cache locality and lower allocation overhead (#3754):

Benchmark	Before	After	Improvement
Table generation	1.578s	1.012s	36% faster
Proof lookup	290ns	204ns	30% faster
Verification	15.5µs	9.3µs	40% faster

• Upgrade polkadot-sdk and frontier from stable2503 to stable2512 (#3766)
• Farmer hardening: disconnect peers on ban, and a cross-platform fix for escaped color codes in logs (#3862)
• Bump Rust nightly to nightly-2026-04-11 (#3782)
• Security-related dependency updates

Build variants

There are two versions of x86-64 builds for Ubuntu and Windows:

• skylake: for Intel Skylake/AMD Ryzen processors and newer
• x86-64-v2: for older processors since ~2009 and some old VMs
• older processors/VMs are no longer supported by official releases, but can still be compiled manually if desired
• x86-64 container images are built for Skylake/AMD Ryzen processors and newer only

Farmer builds with -rocm suffix are for plotting with AMD GPUs.
