# Bitcoin Core dev meeting: October 8, 2026 **Review #35641 (kernel tracer) and #36476 (pruned IBD).** (22 participants, IRC #bitcoin-core-dev) ## Discussed - Kernel WG: sedited merged #34374 for struct-based logging; requested review for #35641 (script evaluation tracer) used in BIP440 integration. - Benchmarking WG: l0rinc proposed #36476, an opt-in pruned assumevalid mode to reduce Pi 4 IBD from ~22 days to under a week. - QML GUI WG: johnny9dev reported good testing feedback, focusing on UX finalization, off-GUI thread functions, regression tests, and feature set for upstreaming. - QA WG: brunoerg launched mutanthub.space's dedicated page for requesting mutation analysis runs for pull requests. - Fuzzing WG: marcofleon confirmed high-quality fuzzing is actively occurring, ensuring code robustness. ## Decided - The regular engineering sync will be skipped next week. ## Next steps - Developers are requested to review #35641 (kernel: Add script evaluation tracer) by sedited. - Developers are encouraged to request mutation analysis for their pull requests via the new dedicated page on mutanthub.space. - johnny9dev's team will focus on finalizing QML GUI UX, migrating functions off the GUI thread with regression tests, and finalizing the feature set for upstreaming. ## Debate No significant technical debate occurred. The most notable proposal was l0rinc's #36476 for faster pruned IBD on low-end devices. PRs mentioned: #34374, #35641, #36476 Full notes:

⚡ Bitcoin Core Dev Meeting Briefing (October 01, 2026) 👥 24 contributors on IRC The Bitcoin Core engineering sync addressed the status of milestone #84 for Bitcoin Core 32.0, with dzxzg requesting developer assistance to clear remaining items. No specific backport issues were detailed, but the call for hands-on review indicates a focus on finalizing the release. This effort is critical for maintaining the release cadence and integrating pending changes. Tooling and architectural updates included significant progress on the QML GUI, where pseudoramdom completed a comprehensive UX overhaul, with the work available in the qt6 branch and pre-built binaries expected on bitcoincore.app. In QA, brunoerg launched mutanthub.space, a new collaborative platform for mutation testing, centralizing mutant submission and evaluation, and replacing previous dedicated sites. For fuzzing, eugenesiegel proposed a bot to automate fuzzamoto builds on PRs, particularly for P2P code. Key decisions included andrewtoth_ stepping down as a lead for the Benchmarking WG, though he will continue contributing to speedup PRs. A notable debate centered on willcl-ark's proposal for a limited trial of automated AI reviews using a 'ralph' bot on PRs. andrewtoth_ and abubakarsadiq raised concerns about the potential for LLM-generated reviews to introduce noise and the necessity for experienced contributors to distill such output, highlighting a focus on review quality over automation volume.
