 | `CVE-2026-34986` | `68e0ba997` | Upgrades `go-jose` to `v4.1.4`. |
 | `CVE-2026-39883` | `1869bd30b`, `e4fa06394` | Updates OpenTelemetry dependencies. |
 | Upstream Go security fixes | [Go 1.26.5](https://go.dev/doc/devel/release#go1.26.5) | Bumps the required toolchain to Go 1.26.5, which includes security fixes to `crypto/tls` and `os`. |
-| Toolchain and dependency refresh | [Go 1.27.0](https://go.dev/doc/devel/release#go1.27) via [`43f4bb7ed`](https://github.com/pgsty/silo/commit/43f4bb7ed), [`edc8be6ed`](https://github.com/pgsty/silo/commit/edc8be6ed), [`4d6e1ea8e`](https://github.com/pgsty/silo/commit/4d6e1ea8e) | Moves the toolchain to Go 1.27.0 and refreshes the dependency stack (etcd client v3.7.1, `jwx` v3.0.13, `klauspost/compress` v1.19.2). The pre-release cleanup then returns to upstream `minio-go` (v7.3.1 pre-release) and retires the `silo-go` fork; `govulncheck` reports no reachable vulnerability on the release candidate. |
