mainnet-2026-jun-14

What's Changed

• Fix a piece-read regression from the Proof-of-Space performance backport (#3754) that could cause "Invalid scalar" read failures when serving pieces to peers; no replot needed (#3867).

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.

What's Changed

• Fix a piece-read regression from the Proof-of-Space performance backport that could cause "Invalid scalar" read failures when serving pieces to peers; no replot needed (#3867).
• Farmer hardening: disconnect peers on ban, and a cross-platform fix for escaped color codes in logs (#3862).
• Minor CI and dependency updates.

mainnet-2026-jun-08

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
