Gloo Gateway vs Inspektor Gadget: at a glance
What is Gloo Gateway?
Gloo Gateway 1.20.29 stops a failed restart from wiping every Envoy's config
Gloo Gateway keeps maintaining 1.19, 1.20 and 1.21 in parallel. The 1.20.29 release fixes a failure where, after a gloo restart, a failed first reconcile sent every connected Envoy an empty config; it also keeps the in-memory Proxy store across setup re-runs and delays setup restarts until the first xDS sync. The 21 October batch had fixed proxies stuck on stale endpoints.
What is Inspektor Gadget?
Inspektor Gadget v0.58 adds SELinux and rename tracing and fixes stale OTel series
Inspektor Gadget v0.58.0 adds trace_selinux for SELinux AVC decisions and trace_rename for file renames, an opt-in OpenTelemetry snapshot mode that drops series for processes that no longer exist, and IPv6 support in trace_sni. The profiler fork was rebased onto upstream, and trace_fsslower's output format changed in a breaking way. v0.57.0 had already let gadgets run rootless with narrow capabilities.

Gloo Gateway 1.20.29 stops a failed restart from wiping every Envoy's config
◆ Current state
Gloo Gateway keeps maintaining 1.19, 1.20 and 1.21 in parallel. The 1.20.29 release fixes a failure where, after a gloo restart, a failed first reconcile sent every connected Envoy an empty config; it also keeps the in-memory Proxy store across setup re-runs and delays setup restarts until the first xDS sync. The 21 October batch had fixed proxies stuck on stale endpoints.
◆ Where it's heading
Recent work concentrates on control-plane failure modes: what Envoy receives when gloo restarts, reconciles badly or sends mismatched endpoint data. Each fix is backported across the supported lines alongside routine Go and dependency bumps.
◆ Prediction
The 1.21 and 1.19 backports of the empty-snapshot fix are the likely next entries, following the same-day batch pattern.

Inspektor Gadget v0.58 adds SELinux and rename tracing and fixes stale OTel series
◆ Current state
Inspektor Gadget v0.58.0 adds trace_selinux for SELinux AVC decisions and trace_rename for file renames, an opt-in OpenTelemetry snapshot mode that drops series for processes that no longer exist, and IPv6 support in trace_sni. The profiler fork was rebased onto upstream, and trace_fsslower's output format changed in a breaking way. v0.57.0 had already let gadgets run rootless with narrow capabilities.
◆ Where it's heading
The project is pairing two tracks: reducing the privileges and trust an eBPF tool needs (rootless runs, multi-tenancy, hardened parsing) and making its output fit standard observability pipelines (OTel metrics and profiles). New gadgets keep widening security-relevant coverage.
◆ Prediction
Expect further OpenTelemetry alignment and more security-focused gadgets; the experimental multi-tenancy from v0.56 has not yet shown a path to stable in the entries.
