October 2025: Release readiness and Go toolchain stabilization across two HashiCorp repos. Delivered RC and preparation work for Consul Dataplane 1.10.0 RC1, upgraded Go toolchain to 1.25.3 with RC2 notes, and upgraded Consul across modules to Go 1.25.3 with DNS SAN compatibility adjustments. Added changelog entries and RC release notes, updating main modules and tests. No major regressions detected; addressed Go 1.25.3 behavior changes to empty DNS SANs. Result: faster release cycles, improved compatibility, and clearer release documentation.

September 2025: Key security, reliability, and Envoy upgrades across Consul and Consul DataPlane. Delivered three major fixes in Consul (path sanitization for proxied URLs, CI workflow hardening to prevent shell injection, Envoy TLS reliability upgrade to 1.35.3) and introduced a new Envoy upgrade with bootstrap validation in Consul DataPlane to require agent_ca_pem when agent_tls is enabled, supported by new tests. These changes reduce security risk, improve TLS/XDS reliability, and make CI processes more predictable.
