[Unreleased]

Added

• Startup warning on Linux when net.ipv4.tcp_slow_start_after_idle is enabled (which resets TCP congestion windows between block requests and significantly reduces single-peer block-propagation throughput on long-haul links), with a "Linux TCP tuning for block propagation" troubleshooting section (#10513)

Zebra 4.4.1 - 2026-05-04

This release fixes one critical security issue. We recommend node operators update to 4.4.1.

Security

• Reject V5 transparent inputs signed with SIGHASH_SINGLE (or SIGHASH_SINGLE|ANYONECANPAY) when the input has no transparent output at the same index (GHSA-pvmv-cwg8-v6c8). Follow-up to GHSA-cwfq-rfcr-8hmp.

Thanks to @​sangsoo-osec, @​zmanian, and @​fivelittleducks for reporting the issue.

Zebra 4.4.0 - 2026-05-01

This release includes several security and bug fixes. We recommend node operators update to 4.4.0.

Security

• Fix sigops counting (GHSA-jv4h-j224-23cc).
• Consensus-divergence defense-in-depth follow-up to GHSA-8m29-fpq5-89jj: the V5 sighash callback now substitutes a per-call CSPRNG-derived sighash when rejecting undefined ZIP 244 hash-type bytes, so any peer-supplied signature fails to verify and the block is rejected in agreement with zcashd (GHSA-gq4h-3grw-2rhv, #10524).
• Allocation amplification in inbound network deserializers: validate coinbase Sapling spend count, coinbase data size, and Equihash solution size before allocating, and enforce the 160-entry cap in read_headers (GHSA-438q-jx8f-cccv, #10525, #10526, #10527, #10528).
