 # Changelog
 
+## 0.26.7
+
+### Backend client lifecycle and cache diagnostics
+
+- Preserve compiled upstream clients when an active-snapshot rebuild leaves the backend origin, address policy, keepalive policy and connect timeout unchanged. This retains Hyper connection pools together with generation age, per-generation request counters and cumulative rotation totals instead of resetting those diagnostics on unrelated configuration rebuilds.
+- Keep incompatible backend changes isolated: changing the origin or any client-construction input still creates a fresh upstream client and fresh generation state.
+- Add a pool regression proving compatible snapshot rebuilds reuse the existing backend/client object; existing upstream-client tests continue to cover age-triggered recycling.
+- Extend `/cache` with explicit HOT and COLD occupancy meters for both configured object limits and byte/disk budgets. Percentages are clamped for progress rendering while the raw counters remain visible.
+
+### Container certificate tooling
+
+- Build the OCI runtime image with a dedicated Certbot virtual environment containing the Cloudflare, OVH and RFC2136 DNS plugins supported by RustProxy, all pinned with the same Certbot release.
+- Refresh container documentation so it no longer tells operators that those provider plugins must be added separately.
