PostgreSQL replication logging, QEMU multi-target, Samba OpenSSL

PostgreSQL hackers iterated on conflict logging for logical replication while QEMU maintainers advanced multi-target linking and architecture fixes. Samba developers separately discussed adopting OpenSSL as a build dependency.

Conflict log history for PostgreSQL logical replication

PostgreSQL hackers are actively reviewing and iterating on patches to add a conflict log history table for logical replication. The work defines how replication conflicts would be recorded and retained over time. Operators and extension authors who rely on logical replication have a direct stake in the design of this history mechanism.

QEMU multi-target helper prefixing

QEMU contributors posted patch series and a pull that introduce TARGET_ARCH_PREFIX and generic HELPER prefixing so TCG helpers link cleanly across multiple targets without ad-hoc renames. Pierrick Bouvier's twenty-patch pull also adds riscv64-softmmu as part of the same multi-target effort. The change reduces brittle rename workarounds for anyone building static multi-architecture QEMU binaries.

Samba considers OpenSSL as a dependency

Samba developers discussed adding OpenSSL as a build dependency for GKDI and future Heimdal integration. The thread cites resolved license issues and a desire to drop hcrypto. The decision would alter Samba's crypto stack and packaging requirements going forward.

HVF ARM fixes ahead of QEMU 11.2

A six-patch series addresses HVF on ARM, covering Windows guest stability, PSCI CPU_ON, and SME/GIC handling. Maintainer review is under way. The fixes aim to stabilize the Hypervisor.framework backend for the 11.2 cycle.

Hexagon H2 firmware support in QEMU

A v2 patch series adds H2 hypervisor firmware binaries and build integration for Hexagon CDSP targets. The work expands firmware coverage for those DSP machine models.

Hexagon subsystem pull for QEMU

A forty-patch pull request delivers Hexagon v85 and DSP machines, MTTCG fixes, UBSan and Coverity cleanups, and related tests. It packages recent Hexagon subsystem work for upstream inclusion.
